Scientists at MIT found that atmospheric inversions—layers of warm air overlaying cooler air—trap heat and moisture at the surface, enabling prolonged and intense humid heat waves in midlatitude areas such as the US Midwest. This trapped energy also fuels severe thunderstorms when inversions break, explaining concurrent patterns of heat waves and storm events.
The study, published in Science Advances, suggests that as global temperatures rise, inversion layers may become more persistent and harder to dissipate, increasing the frequency and severity of humid heat waves and storms in regions not typically prone to such extremes. This insight offers climate scientists a new tool to estimate local weather risks under climate change.
