An international team of scientists found that volcanic eruptions can cause the Pacific Walker Circulation to temporarily weaken, inducing El Niño-like conditions. The results provide important ...

Right now, the world’s best weather forecast model is a General Circulation Model, or GCM, put together by the European Center for Medium-Range Weather Forecasts. A GCM is in part based on code that ...

But using AI is still extremely tempting because the alternative is a computational atmospheric circulation model, which is extremely compute-intensive. Still, it’s highly successful, with the ...

This is a schematic of the trends in temperature and ocean-atmosphere circulation in the Pacific over the past two decades. Color shading shows observed temperature trends ( C per decade) during ...

While there is substantial evidence for tropospheric jet shift and Hadley cell expansion in response to greenhouse gas increases, quantitative assessments of individual mechanisms and feedback for ...

During a La Niña, a counterpart to the El Niño weather pattern, drier than normal conditions are to be expected. But 2023, a La Niña year, turned out to be California’s 10th-wettest year on record.

July 19 was the hottest day ever recorded in the United Kingdom, with temperatures surpassing 40 degrees Celsius (about 104 degrees Fahrenheit). The heatwave serves as an early preview of what climate ...
