Abstract
Sudden Stratospheric Warming (SSW) events are extreme increases in polar stratospheric temperatures (10s of Kelvins) over several days. They happen nearly yearly in the Northern Hemisphere, but they’re rare in the Southern.
Planetary Waves (PWs) are large-scale perturbations of the atmospheric dynamical structure that extend coherently around a full longitude circle. (A. K. Smith, 2003)
The exact relationship between SSWs and PWs is not known, but in September 2019, there was a Southern Hemispheric SSW (2nd ever recorded) which coincided with a strong PW activity. In this investigation, we examined the PW to better understand whether this PW activity extended into the mesosphere, and what the properties of this wave are.
