Sudden stratospheric warming (SSW) refers to a rapid increase in temperature in the stratosphere, particularly over the polar regions, that can occur in winter. This phenomenon typically involves a significant change in the dynamics of the atmosphere, primarily affecting the polar vortex, which is a large area of low pressure and cold air surrounding the Earth’s poles.
