Earlier in the month many parts of New Zealand had frosts. Since we are now into the beginning of spring, it got me thinking about the impact that late season frosts can have on the delicate buds sprouting on trees and vines around the country.
After a week of sunny weather, it appears that rain will dampen Waikato Stadium before this weekend’s Tri Nation rugby game starts there at 7:35pm on Saturday.
This clash between the Springboks and the All Blacks is the first Tri Nations game to be held at Waikato Stadium (capacity 25,800).
Our weather in New Zealand is greatly modified by the shape of the land. There are many parts of the country where the air is channeled through gaps in the terrain, and I thought I would write a little about this. Especially since it relates to the thread of my earlier posts on wind.
On 21 August in 1861, Dr. Charles Knight was appointed the first Director of Meteorological Stations in New Zealand.
One of the pleasures of reading history is coming across stories about the weather. Thunderstorms often figure in these. One of the most dramatic examples was recorded in the sixth century AD, by Gregory, Bishop of Tours, in his Historia Francorum (The History of the Franks). In AD 536 there were three rulers of Frankish kingdoms: Childebert, the king of Paris; his brother Lothar, the king of Soissons; and the brother’s nephew Theudebert, the king of Metz.
In my blog post about winds aloft there is a loop of satellite images for a week in winter 2008. It shows that the big cloud features in the mid-latitudes typically travel from west to east. In other words, the features you see on weather maps affecting New Zealand have usually started out roughly in the area of southern Australia.
On the night of 17th July and early on the 18th, New Zealand was affected by a fast-moving and rapidly deepening depression originating in the north Tasman Sea. Sustained southwesterly winds of more than 60 knots were recorded in Colville Channel as the low passed by. Severe Weather Warnings were issued for wind in Coromandel/Great Barrier Island and rain in the eastern North Island.
Part of my job as a teacher of meteorology is to go to NZ universities looking for future meteorologists. It breaks my heart when, sometimes I meet a person with a genuine passion for the weather who would love to work for us as a meteorologist, but just can't cope with the required maths. Unfortunately for them, professional meteorologists need to have some university maths under their belts. And this requirement isn't just a local thing - it also comes from the World Meteorological Organisation of which we are a member nation.
When I was biking to work this morning I noticed prolific amounts of pine pollen in the puddles around Westhaven.
