Stratospheric warming

From Glossary of Meteorology



stratospheric warming

(Also called sudden warming.) A rise in temperature of the stratosphere in the polar region in late winter resulting from enhanced propagation of energy from the troposphere by planetary-scale waves.

Temperatures near 50 mb can increase by as much as 40°C in just a few days.
