Weather Place Names

There is a lot of weather tied up in New Zealand place names. The screaming northwest gales of Canterbury are celebrated with names like Windwhistle, near the Rakaia Gorge, Mount Blowhard, near Oxford, and Nervous Knob, near Castle Hill, where gusts of 240 km per hour have been measured.

Fine weather gets a mention with Sunnynook and Sunnyvale, both near Auckland. We have a Misty Peak and a Cloudy Bay and rainbows are well represented, being used to name an island, a mountain, a lake and a pass. Rain itself is harder to come by but can sometimes be found in the story that gave rise to a name.

Fittingly, several of these occur in rainy Fiordland. Monkey Creek, for example, commemorates a downpour that flooded a creek and washed away a surveyor’s dog, called Monkey, who fortunately made it back to camp the next day. Also in Fiordland Stick-up Creek was named by Martin’s Bay settlers, who were held up by a flood, while Mount Soaker speaks for itself.

In May 1773 James Cook laconically named Wet Jacket Arm in Dusky Sound after a storm forced an exploring party to stay out overnight. In Lieutenant Pickersgill’s words “On the 7th I went with the Pinnance to explore a Sound, expecting to get back on the same Night but was disappointed for it came on a very violent storm of Snow Hail and Thunder with a meer Hurrican of wind which confined us in a little Cove, and what was worse we had nothing to eat but a few Mussels which we gathered from the Rocks and nothing to drink but spring water; in this situation we were kept for 36 hours, quite wet and the woods so wet we could not get a bit of fire to burn and being entirely exposed to the inclemency of the weather.”

The naturalist, Forster, was rattled by the ferocity of the storm “ it seemed as if all nature was hastening to a general catastrophe … our hearts sank with apprehension lest the ship might be destroyed by the tempest and its aetherial fires, and ourselves left to perish in an unfrequented part of the world.”

There is also a storm hidden behind Cook’s naming of Hawke’s Bay. First Lord of the Admiralty, Edward Hawke, rose to fame as the only naval commander in the age of sail to initiate a battle in a full gale.  In November 1759, Hawke ordered his fleet to pursue the French as they retreated into Quiberon Bay seeking a safe harbour. The English ships crammed on so much sail in the chase that some of them sustained damage. The seas were so large that water entered some ships through their gun-ports. One of the French ships capsized and sank in a squall when this happened while the English ships managed to right themselves and shed the water.

Caught off balance by the audacity of Hawke’s attack the French Admiral never regained the initiative. The result was a crushing victory, which ended all hope the French had of transporting their large army of invasion to England. Had the English not won the war, some historians speculate that the USA might be speaking French today and not English.

There are also a host of Maori weather stories in New Zealand place names, as a trawl through A.W. Reed’s excellent Place Names of New Zealand will show. Kaihau-o-Kupe near Wanganui remembers a time when Kupe was held up by persistent westerly gales and rough water and had to “eat the wind” as he had no food with him.

Tongaporutu near Waitara translates as “driving into the south wind at night” and was given by the explorer Whatonga when he was sailing down the west coast searching for his grandfather Toi.

Upokopoito near Wanganui translates as “calabash heads”. The story goes that a red-headed chief heard that fishermen had mockingly compared him to a red gurnard. A tohunga obliged the chief by calling up a gale that swamped the fishermen, whose heads bobbing in the water looked like calabashes.

The Maori name for Wellington’s Mount Victoria is Tangitekeo, literally “the sound of the peak” as this was where the taniwha Whaitaitai screamed, a sound like the howling of the wind.

As befits a country astride the roaring forties, many names reference the wind. The Maori name for Solander Island in Fovueax Strait is Hautere, or flying wind while elsewhere there is a Hauiti, or little breeze, a Haunui, big wind or frequent wind and a Haumoana or sea wind.

Quite a few names commemorate misfortune, such as the numerous coastal features named after ships wrecked in storms: Benvenue Cliffs near Timaru; Buffalo Beach in the Coromandel and Union Bay near Auckland.

Mount Paske is named after a surveyor who lost his life in a snowstorm while Canterbury’s Jason’s Creek remembers a man who got severe frostbite cutting firewood and had both legs amputated at the knees.

Graveyard Gulley near Alexandra is named for two travellers killed in a snowstorm while Deadmans Terrace, on the Shotover River, is where eleven gold prospectors were killed in a horrendous flood.

A touch of humour is evident in The Gluepot, which occurs in Otago and Westland for places where carts were regularly bogged down after rains turned to roads to quagmires.

Among the many names bestowed during the voyage of the survey ship HMS Acheron in the 1840s was Blanket Bay in Fiordland, after a blanket of fog encountered there. Acheron made its way into several place names and was originally the name of a river in the Greek Underworld. Interestingly, some scholars believe the syllable ach goes back thousands of years further and is an Indo-european root word associated with streams that gave rise to the latin word aqua.

Perhaps the most delightful discovery in Reed’s book concerns a place on Banks Peninsula called Snefellness by a Danish whaling captain in 1840. It means a promontory surrounded by a snowfield and is now mispronounced as Snufflenose.

Benjamin Franklin – Electrical Ambassador

(First published in new Zealand Geographic 96, March-April 2009)

We think of Benjamin Franklin as American, but for the first seventy odd years of his life he thought of himself as British. In turn, the British thought him one of theirs and embraced Franklin’s ideas and inventions as British discoveries.

For example, on his first voyage to New Zealand Captain Cook carried one of Franklin’s lightning conductors. Caught in a thunderstorm in Batavia (Jakarta), the Endeavour was struck by lightning but unharmed while a Dutch ship nearby had its mainmast shattered.

On 18 May 1773, during his second voyage to New Zealand, Cook was sailing the Resolution towards Stephen’s Island when he met with six waterspouts. As the sky darkened with cloud threatening strong winds, he ordered all sails “clewed up” to lessen the risk of damage. Four waterspouts rose and spent themselves between the ship and the land, a fifth was out to sea, but the sixth passed about 50 metres away from the stern of the Resolution.

Cook was familiar with Franklin’s theories about waterspouts, in particular, Franklin’s speculation that a large gun fired into one would disrupt it. Franklin, on horseback and armed with two pistols, had once chased a whirlwind down a country road in Virginia but it got away over a fence before he could shoot it. Cook endeavoured to try the experiment and ordered a cannon loaded and aimed but the waterspout had moved out of range by the time the gun was ready.

Franklin’s work on electricity won him international renown. The experiments he proposed, in a paper published by The Royal Society, proved that lightning was a form of electricity. This had long been the subject of speculation. Newton, for example, had described a spark jumping between the tip of a needle and a piece of amber rubbed with silk “The flame putteth me in mind of sheet lightning on a small – how very small – scale.”

Representation of waterspout accompanying "Water-spouts and Whirlwinds" by Benjamin Franklin. Figure III represents the semimagic square Benjamin Franklin constructed in 1750 having magic constant 260.

Franklin proposed building a sentry box on a tall tower with a 10 metre iron rod connected to an electrical stand. A person holding a grounded wire by insulated handles could draw sparks from the iron rod to the wire when an approaching thunderstorm charged the rod.

While Franklin waited for a tall tower to be built in Philadelphia he hit upon the idea of flying a kite into a storm and drawing sparks from a key attached to the kite string. By the time he successfully carried this out in June 1752 his original experiment had twice been successfully conducted in France, although news of this had not yet reached America.

Franklin was the first to use the terms positive and negative to describe electric charge. He also came up with the concepts of batteries and capacitors and the distinction between insulators and conductors.

Aside from explaining the nature of lightning, Franklin made other contributions to meteorology. He explained the paradox that an easterly storm could affect Philadelphia before it reached Boston, even though Boston lay further east. The answer was that the storm was a large whirling vortex of wind that moved eastwards across the land.

He correctly deduced from summertime hail that there must be a high layer in the atmosphere where temperatures were always as cold as winter. He astutely blamed volcanic eruptions in Iceland for “dry fog” experienced throughout the northern hemisphere in 1784 that brought an extremely cold winter.

Franklin had time to indulge in scientific speculations, as well as enter politics, because he had been so successful as a printer he was able to retire at forty-two. Among his popular productions was Poor Richard’s Almanack which contained information on tides, moon cycles, weather, sundry advice and pithy sayings such as “A countryman between two lawyers is like a fish between two cats.”

Borrowing a trick from Jonathon Swift, Franklin predicted the death of a rival. When the due date arrived, he pronounced the man dead. When his rival claimed to be still alive, Franklin dismissed the protests as a cruel hoax perpetrated by others trying to make money from the dead man’s name.

Franklin’s weather forecasts a year ahead were also tongue in cheek – “Ignorant men wonder how we astrologers fortell the weather so exactly…Alas! ‘tis easy as pissing abed. For instance: the stargazer peeps at the heavens through a long glass; he sees perhaps Taurus, or the great bull, in a mighty chase, stamping on the floor of his house, swinging his tail about …Distance being considered, and time allowed for all this to come down, there you have wind and thunder.”

Franklin’s scientific work made him the most famous American in Britain and Europe. He was the first person outside Britain to receive the Royal Society’s Coply medal. Hailed by the German philosopher Immanuel Kant as the “modern Prometheus”, Franklin was elected a foreign associate of the French Acadamy of Sciences and received honory degrees from numerous universities.

In politics he played a vital role in the decades before the American Revolution. Once war broke out, he helped write the Declaration of Independence then was given the crucial task of handling the French alliance. Hailed as the “electrical ambassador” in France, the French statesman Turgot said of Franklin “He snatched lightning from heaven and the sceptre from tyrants.” One portrait showed Franklin enthroned in the sky surrounded by winged deities with a lightning bolt behind him. Louis XVI, although helping the American cause, had a Sevres chamber pot made with Franklin’s portrait inside as a gift for one of Franklin’s admirers.

By the time Britain was defeated and a treaty negotiated, Franklin was eighty. Sailing home, he found time to measure the depth of the Gulf Stream using a corked bottle on a thirty-five fathom line. The pressure at depth forced the cork into the bottle followed by deep water. Pulled back to the surface, the water temperature was 12 F colder than the surface, proving that the Gulf Stream was a relatively shallow layer of warm water.

Back on land, Franklin returned to politics and helped revise the Constitution, before dying aged 83, one of the most remarkable statesmen-scientists the world has seen.

Rugby Weather: Fog

Rugby and fog do not go well together. Fortunately, in the days when rugby was played in the afternoon, they did not meet up much, except for the occasional test in Scotland when the All Blacks disappeared into the “gloom” as they scampered in a late try.

However, the introduction of night-time rugby gave fog a chance to get on the field for some game time. Especially in the United Kingdom, where evening games sometimes have to be cancelled when fog turns up.

In New Zealand, fog showed us what it could do when it rolled into Christchurch an hour before the kickoff of the Super 14 final between the Hurricanes and the Crusaders on 27 May 2006.

As a television spectacle the event was seriously compromised. The cameras down at ground level sometimes got a reasonable view but those high up were mostly obscured. Nicknamed “gorillas in the mist” the contest was won 19-12 by the Crusaders.

The Hurricanes, who do not have much fog of their own as it is usually too windy in Wellington, also got to suck up some Hamilton fog at the end of the Super 14 semi-final against the Chiefs in May 2009, which they also lost. Situated on a river, with swamps nearby, Hamilton is the most fog prone major city in New Zealand. After Hamilton, Christchurch is the next foggiest because it is close to the sea, so the air is often very humid.

Fog formation is helped when there are a lot of condensation nuclei in the air. Many of these come from tiny plants in the sea known as phytoplankton. When tiny animals, known as zooplankton, nibble phytoplankton the chemical dimethylsulfoniopropionate is released into the water. There it changes to dimethyl sulphide (DMS) which gets into the atmosphere when breaking waves throw small water droplets into the air, where they evaporate.

In the air, DMS changes to four different chemicals, three of which act as cloud condensation nuclei. DMS also helps make the characteristic smell of the air at the beach.

Smoke particles can also act as condensation nuclei. Indeed, the celebratory fireworks after the Crusaders victory resulted in a temporary thickening of the fog in Christchurch. During the Napoleonic wars so much smoke was produced by the massed cannon-fire that fog would sometimes envelope the battle field giving rise to the term “the fog of battle”.

Before the clean air laws were enacted, smoke from coal fires and industry used to cause the famous pea-soup fog in London. In December 1952, a notorious fog lasting for days was blamed for 4000 fatalities, mostly from bronchitis and pneumonia. Breathing this particular fog actually caused pain as a portion of the 1000 tons of dirt particles suspended in the London air was sulphur dioxide which combined with water droplets and oxygen to form sulphuric acid.

Some playing-fields in Scotland have underground heating to prevent the soil freezing when frost strikes but there is not much you can do to prevent fog. During the Second World War a lot of effort went into discovering a way of clearing fog from airfields.

The only method that worked, and then only temporarily, was burning petrol sprayed from long pipes either side of the runway so that planes landed between walls of flame. But at nearly 30,000 litres of petrol per landing, it was prohibitively expensive.

Fog is just cloud resting on the ground, and clouds are often found resting on the mountains. So even before night rugby came to New Zealand there was one place where fog frequently turned up before game time and that was the coal mining settlement of Denniston, situated on a plateau 600 metres above sea-level on the South Island’s West Coast.

Although good for fog, Denniston was not a particularly good place for soil and grass. The rugby ground had been bulldozed out of rock and was covered in new load of sand brought up from the beach at the beginning of each season.

Rugby in the fog had certain disadvantages. A ball kicked high in the air, for example, would disappear and players have to wait around for the telltale thump to discover where it came back down.

There was, however, some home advantage. Visiting teams found playing in the persistent fog somewhat confusing, and if the game was going badly for the home team an extra player could be slipped on in the backline to stiffen the defence.

Nor was this astute use of local conditions restricted to the rugby team. An excellent soccer team from Millerton was once unable to make headway against Denniston until the fog lifted, revealing that Denniston had four extra players on the pitch.

Rugby Weather: Scotland in the Rain

The All Blacks were due to play Scotland in Auckland on 14 June 1975 when a major storm hit New Zealand. Torrential rain fell over many parts of the country inundating farmland from Northland to Canterbury. Roads in Northland were cut by floodwaters metres deep and the Mangakahia River rose 10 metres above normal.

Tragically, a 12 year old boy drowned on Auckland’s North Shore when he slipped into a flooded stream and was washed into a culvert. Surface flooding occurred in parts of Auckland. A million dollars worth of stock was destroyed when water entered the basement of a Nestlé’s warehouse and an old lake reformed in Remuera which proved suitable for dingy sailors while it lasted.

A tornado struck near Huntly, in the Waikato, knocking over a line of power poles and destroying a hay barn, parts of which flew over the heads of children playing nearby. A service station at Waerenga was ripped apart and a number of houses damaged. Fallen trees cut roads and brought down power and phone lines in many other parts of the country.

Slips and floodwaters cut roads in the Coromandel and some small boats were washed away at Te Kaha when large waves ran up beyond the high tide mark.

Cook Strait ferry sailings were cancelled due to the high winds around Wellington. Waves washed away shingle undercutting the railway line to the Hutt Valley and roads were closed at the northern end of the harbour by seas washing driftwood and seaweed over them.

The railway line between New Plymouth and Wanganui was cut by a washout while a slip closed the main trunk line south of Kaikoura. Slips also blocked the roads through the Buller Gorge and the Kawerau Gorge. Snow fell over inland Canterbury with 18cm accumulating on the road at Porter’s Pass and 46cm at Burke’s Pass.

At Auckland’s Eden Park, around 75mm of rain had fallen by kickoff. The ground had sold out but 10,000 spectators stayed away. Some spectators had to walk through ankle deep water to get to their seats. Consideration was given to postponing the game but conditions were not expected to be a lot better the next day and the Scots were booked to fly home on the Monday.

So the game went ahead although the referee blew up the rucks very quickly to avoid anyone drowning under a crush of bodies. The All Blacks turned on some great wet weather rugby winning 24-0. The first try was the result of a running move but the other three came from the classic tactic of kick and chase exploiting mistakes in the defence’s handling of the wet ball.

The ground held up surprisingly well and did not turn into a quagmire. Although the ball was slippery, it did not become so heavy as to prevent Joe Karam converting all of the All Blacks tries.

In the early days of rugby, wet balls often became hard to kick over the cross-bar. In the famous mud-battle at Athletic Park between the All Blacks and the Anglo-Welsh in 1908 the game finished a 3-3 draw when the visitor’s goal-kicker failed to convert a try between the posts as he barely raised the sodden ball out of the mud.

Wet weather used to be regarded as the great equaliser, giving a lesser team a chance against a stronger team. However, the introduction of synthetic balls in the 1980s restored the advantage. As well as being waterproof these new balls had thousands of dimples on their surface to improve the players grip when the ball was wet.

A classic example of the standard of play now possible on a wet ground was seen in the first tri-nations test played between the All Blacks and the Wallabies at Athletic Park in a wet southerly on 6 July 1996. The All Blacks ran in 6 tries to none winning 43-6 and were denied a chance at 50 points when the referee ended the game 3 minutes early when they were hot on attack.

Rugby’s ability to live with the rain has also improved enormously with modern turf engineering which allows the top test venues to drain water away at a rate undreamt of by previous generations. Nevertheless, extreme rainfalls from a thunderstorm can exceed 100mm in an hour so if a thunderstorm parked itself in just the right place at just the wrong time it could still cause trouble. Except, of course, in Dunedin where they have gone for the ultimate solution and put a roof over the ground.

Rugby Weather: Snow and the Lions

The first test between the All Blacks and the Lions in 1930 was played at Dunedin’s Carisbrook Park just after a snowstorm. Rain started in the morning then turned to snow during the curtain raiser. It became almost impossible to make out the players and some of the crowd went home while others sheltered under blankets and umbrellas.

The snow eased to sleet as the test teams came onto the field then cleared soon after. However, the ground by this time was quite heavy and slippery making expansive back play difficult. The score was 3-3 going into the last minute. The All Blacks were hot on attack, when Great Britain’s Ivor Jones intercepted a pass and took off downfield. As he was tackled by George Nepia he passed to his winger who scored a spectacular try in the corner bringing the crowd to its feet and secured a 6-3 win for Great Britain.

The snow affected eastern areas of the South Island and was regarded as the heaviest in more than a decade. Southland and south Otago were worst hit with many roads closed, delaying spectators trying to return home after the test. Gore had 15 cm while some places as much as 23 cm. When the train carrying the Great Britain rugby team to Invercargill on the Sunday stopped at Gore, the players started a snowball fight amongst themselves before uniting and bombarding the crowd that had turned out to greet them.

The Great Britain team must have become well acclimatised to snow by the time of their game against Ranfurly Shield holders Southland on the Wednesday. There was a bitterly cold wind and further snow fell but Great Britain won 9-3.

The Southland rugby team were no strangers to snow and famously defeated Manawatu in a Shield defence in 1939 when the ground was covered in 10 cm of snow (see my previous blog).

A previous Great Britain team also had a close encounter with snow when it played Canterbury-South Canterbury-West Coast combined at Lancaster Park on 6 August 1904 in the opening game of its tour. Although the weather for the game was fine, snow had fallen earlier in the week and had to be cleared from the playing field.

Fortunately for the home team the snow had not been completely cleared from the in-goal area. Their only try was scored when a defender tried to kick the ball dead only for it to hit the snow and stop. Future All Black Bob Deans dived on it to score. However, the conversion failed and Great Britain won 5-3.

A year later, Deans scored the controversial try that was disallowed when the 1905 All Blacks suffered their only defeat, losing 0-3 to Wales.

While snow occasionally comes to the house of rugby, rugby sometimes goes to the house of snow. In Antarctica there is an annual rugby match between the scientists at Scott Base and those at McMurdo.  Played on a groomed snow surface on top of two metre thick sea ice the Ross Island Cup has been won by New Zealand for 27 years straight. The New Zealand supporters distribute “Rugby 101” leaflets to the US supporters to help them understand the rules.

Closer to home is the Glacier Country Cup disputed annually by seven aside teams the Cunning Foxes and the Franz Josef Eagles on a pitch 2340 metres above sea level. The players, crowd, goalposts, touch-lines and try-lines are all carried up by helicopters.

As winners of the latest match, The Cunning Foxes, hosted a Spanish women’s team, Unio Esportiva Santboiana from near Barcelona. The visitors carried the day with a running game the locals could not match. However, the Spanish women did not arrive in New Zealand entirely ignorant of our style of rugby as the sporting director of Unio Esportiva Santboiana is the former All Black hooker Bruce Hemera.

Rugby Weather: New Zealand v South Africa in the Rain

On Saturday 17 September 1921, the deciding test of the first Springbok Tour was played at Wellington’s Athletic Park. New Zealand had won the first test 13-5 at Carisbrook and South Africa the second test 9-5 at Eden Park.

Unfortunately, after a long dry spell, rain began on the Friday evening and continued throughout the weekend. Of the 131mm that fell in Wellington, 42mm had fallen by the end of the match. Although the rain, which fell over a large part of the North Island, was welcome to farmers, it caused a number of slips and flooded parts of the Miramar Peninsula and the Hutt Valley. The Hutt River stayed within its banks but delivered the carcase of a dead horse to Petone Beach.

The Athletic Park ground had been hard after the dry spell and the rain could not easily drain away, resulting in several respectable sized lakes on the playing field. The curtain raiser was cancelled and the crowd had to entertain themselves.

The slippery clay on the western bank helped, as it became a great spectacle to watch people negotiate their way over its treacherous surface. Particularly those under the influence of liquid refreshments, some of whom came slithering down on their hands and knees. Part of the bank gave way, to the distress of a group of young women who came down with it, but generally the crowd was in good spirits despite being soaked.

Food fights broke out, mostly orange peel and banana skins but one crayfish was seen flying through the air. It landed on an umbrella and was partially impaled on the stick while the remains broke through the umbrella fabric and ended up in the victims lap.

Vendors were selling umbrellas outside the ground for 15 shillings and 6 pence, as against a normal week-day price of 3 shillings and 6 pence. Military surplus oilcloths were also on sale and wooden cases to sit or stand on cost 1s and 6d, rising to 3s and 6d as supplies ran low close to kick-off.

Fortunately, the wind was only a light southerly, but the rain was not conducive to good rugby. The game was described as more like water polo with the ball like grease and the ground turning into a veritable quagmire. It became a mud slog between the forwards. There was a lot of kicking and chasing, with the ball coming to an abrupt halt when it hit the deeper puddles.

One penalty shot for goal barely left the ground. A Springbok forward got over the New Zealand line but was on his back and could not force the ball before it was ripped out of his hands. An All Black back was in the clear with the South African line open but lost his footing in a small lake.

A brief interruption occurred in the second half when the referee slipped over and was accidently kicked in the head by a Springbok forward. He was able to continue but collapsed after the end of the game. His absence from the after match function sparked a rumour that he had died when he was actually safe at home in bed.

The Springboks were considered to have had the best of the first half and the All Blacks the best of the second half, but the game ended in a scoreless draw.

In a speech after the match the South African Manager said that he could not think of a happier ending to the tour -

“As our hosts, I am sure you would have been very unhappy if you had beaten us; as your guests we would have been very unhappy if we had beaten you. I can reflect the opinion of every one of you when I say that the best team drew.”
