Cold Air Rises. What That Means for Earth's Climate. - UC Davis : Conventional knowledge has it that warm air rises while cold air sinks. But a study from the University of California, Davis, found that in the tropical atmosphere, cold air rises due to an overlooked effect — the lightness of water vapor. This effect helps to stabilize tropical climates and buffer some of the impacts of a warming climate. The study, published today in the journal Science Advances, is among the first to show the profound implications water vapor buoyancy has on Earth’s climate and energy balance. (Kat KERLIN, U. C.
