Extratropical and High-latitude Storms, Teleconnections, Extreme Events, and the Rapidly Changing Polar Climate

Session ID#: 72510

Session Description:
Synoptic storms and large-scale teleconnections are prominent dynamic drivers for daily-to-decadal climate variability in the extratropics and high-latitudes and can interplay with external forcings to contribute to long-term climate change. Storms often bring extreme events, including heavy rainfall or snowfall, high winds, large ocean waves and surges, coastal flooding and erosion, abrupt temperature increases, and rapid sea ice loss. Teleconnections link polar and lower latitude climate and play modulating roles in storm activities. Storms and teleconnections have demonstrated systematic changes, leading to alterations of feedback processes and contributing to anomalous variability and changes of climate. This session provides a venue to present progress on extratropical and high-latitude storm activities, teleconnections between extratropics/tropics and the polar regions, resulting extreme events, and underlying physical processes (e.g. stratosphere-troposphere coupling, Rossby wave and jet stream dynamics, wave-mean flow interactions), along with the rapidly changing polar climate, as well as associated ecosystem- and societal impacts.
