Storylines of regional climate change

By Giuseppe Zappa  An outstanding question for climate science is quantifying how global warming will regionally affect the aspects of climate that are most directly relevant to society, such as precipitation, windiness and extremes. But achieving this task is proving … Continue reading

How the Hadley Cells work

By Gui-Ying Yang The Hadley Cell, named after British meteorologist George Hadley who discovered this tropical atmospheric overturning circulation, is one of the basic concepts in weather and climate. Figure 1 shows the zonal mean overturning circulation in a latitude height … Continue reading

Mechanisms of Climate Change in the Indian Summer Monsoon

By Jon Shonk Over one billion people are reliant on the rainfall of the Indian Summer Monsoon. During the wet season, which usually spans June to September, some parts of India receive over 90% of their total annual rainfall. Deficits … Continue reading

Clouds, climate and the Roaring 40s

By Richard Allan In our new research we have traced large and long-standing biases in computer simulations of climate, affecting the tempestuous Southern Ocean, to errors in cloud that emerge rapidly within the atmospheric models. Biases evolve over time through … Continue reading

Why was the sky Orange?

By William Davies I was sitting in my house one morning in October 2017, engrossed in what I was doing. Gradually I noticed that an eerie darkness was smothering the natural light in the room. I stopped and looked outside. … Continue reading

Exploring the impact of Gulf Stream temperature biases on the global atmospheric circulation

By Robert Lee The climate state in numerical models often have differences when compared to a climatology from observations. These differences are often termed ‘biases’ and can be considered as a kind of error or deficiency in the model. These … Continue reading
