Himawari Satellite Data

The Japan Meteorological Agency launched a geostationary weather satellite called Himawari-8 in October 2014. “Himawari” means sunflower, and the name has been given to a series of satellites that we can look forward to in coming years. “Geostationary” means the satellite rotates “in sync” with the Earth, always above the same point over the equator.

Weather for Flying - Turbulence

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.

The nature of turbulence

A rare July Tropical Cyclone

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.

Meteorologists and astronomers both spend a lot of time looking at the sky—this webcam image from the weather station at Invercargill captured a lovely example of the Aurora Australis. In the foreground are the instruments used to measure cloud height and the type of weather. The Aurora was also captured by Astronaut Scott Kelly on board the International Space Station see his photos here.

Snowfall in New Zealand

New Zealand is well known for its spectacular mountain ranges especially during the winter when they are covered in a fresh layer of snow. It is not usual to see that snow level dropping down below the mountains but when it does it can cause disruption to New Zealand’s public travel networks.

Flying under the RADAR

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.
