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 ...

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 ...

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 ...

The Atlantic Meridional Overturning Circulation (AMOC), an ocean current system that transports heat from the tropics to 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.
