Global Atmospheric Circulation

What causes our weather? Why is it much warmer at the Equator than it is at the Poles? What are the trade winds?

The Earth’s rotation and the Sun are the main causes of the diverse weather experienced in different parts of the world every day. A previous article published on theWeather Club explores the processes involved in creating atmospheric circulation cells and the impact they have on global weather patterns.

Pyrocumulonimbus Clouds theWeather Club Wed, 15/07/2020 - 12:34

Pyrocumulonimbus clouds are thunder clouds created by intense heat from the Earth’s surface. They are formed in a very similar way to cumulonimbus clouds, but the intense heat that results in the vigorous updraft comes from fire, either large wildfires or volcanic eruptions. It is for this reason the prefix ‘pyro’ is used – meaning fire in Latin. Pyrocumulonimbus clouds were reported during the Australian bushfires in late 2019/early 2020 and a number have more recently been observed in Siberia with the Arctic heatwave.

Scottish Snow Patches Report 2019/2020

Iain Cameron and Blair Fyffe have just published the 24th annual report on the survival of Scottish snow patches in July’s issue of Weather. Iain is a researcher of UK snow patches and publishes his findings in the Royal Meteorological Society’s scientific papers twice a year. He and his team of volunteers have been exploring the Highlands for over 15 years and his findings have supported climate scientists in their understanding of how our changing climate is impacting our landscape.
