The <scp>January</scp> 2021 sudden stratospheric warming
Simon H. Lee
Abstract
On 5 January 2021, the Arctic stratospheric polar vortex dramatically weakened, and the temperature of the Arctic stratosphere rapidly increased in an event known as a major sudden stratospheric warming (SSW). It is likely that this SSW influenced surface weather conditions for over a month afterward.
