Seminar Abstract:

Sudden stratospheric warmings (SSWs) are first-order dynamical events in the polar winter stratosphere, which are known to influence tropospheric variability on medium range time scales of roughly 10-60 days. Here we present results from the development of a SSW compendium composed of processed data derived from six modern
reanalysis products. The aim of this compendium is to provide an opensource and maintained repository of research-ready data for the scientific community and of outreach products for the general public.

For the scientific community, these data will allow for more rapid and effective study of the dynamical evolution and tropospheric coupling of SSWs, with particular emphasis on the latter. Additionally, production of the compendium from multiple reanalysis sources allows both for intercomparison of these sources and for analysis of SSWs across various resolutions and time spans.
