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?

As weather enthusiasts, these might be a few questions you find yourself asking. 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.

What is a Hurricane?

What is a Hurricane?

Tropical Storm Hanna became the first hurricane of 2020 in the Atlantic over the weekend. The hurricane made landfall on the Gulf Coast of Southern Texas on Saturday, bringing extremely heavy rain and risk of flooding to the area. Winds were recorded at 90mph, making it a category 1 hurricane.

What are hurricanes and how are they formed?

Pyrocumulonimbus Clouds

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.

Weather Forecasting ‘Fantasy League’ Game

Wannabe weather forecasters can play a fantasy league of a different kind this summer, as a new game is launched by the University of Reading.

The Weather Game offers the chance to try and predict the weather in set locations around the world, using data from world-leading organisations. Points are awarded for correct forecasts, allowing people to take on their friends and beat the experts to top the league.
