Have you ever thought that for aeroplane pilots, every day at work is a blue-sky day? Soaring above the clouds you might think that the weather isn’t such a big deal. But this couldn’t be further from the truth. Pilots are dependent on weather information at every stage in their flights. In this blog post, we discuss one crucial aspect of aviation weather that affects both pilots and passengers – turbulence.
Tropical Cyclone Raquel was named at 6am on 1 July 2015, located at 5.8° South 159.3° East, some 410km north-northwest of Honiara, the Capital of the Solomon Islands. The maximum winds near the centre were estimated at 35 knots (65km/h). Whilst the consensus of computer models suggest Raquel will track slowly southwest over the Solomon Islands during Thursday and Friday, some models move the system towards the southeast, possibly affecting Vanuatu and/or New Caledonia in the coming days.

The term RADAR stands for RAdio Detection And Ranging and was coined in 1940 by the United States Signal Corps, although it was German physicist Heinrich Hertz who showed that radio waves could be reflected from solid objects, in around 1886. During World War II, radar technology developed rapidly and has since become an essential tool in meteorology, as well as in other areas such as air traffic control.

The wisdom of the crowd At a county fair in Plymouth, England, in 1906, several hundred fair-goers entered a contest to guess the weight of an ox. The average guess was extremely close to the true weight of the beast – even though some of the individual estimates were wildly off the mark!

Out over the Tasman Sea, a warm and moist weather system is gradually making its way southeast towards New Zealand. Meanwhile cold weather is brewing in the Southern Ocean – preparing to blast the warm air away.
