Extratropical and High-Latitude Storms, Teleconnections, Extreme Weather, and the Changing Polar Climate I

Session ID#: 11012

Session Description:
Synoptic storms and large-scale teleconnections are prominent features characterizing daily-to-decadal climate variability in the extratropics and high-latitudes. Storms often bring extreme weather, including high-wind events, large ocean waves and surges, coastal flooding and erosion, as well as rapid temperature changes. Teleconnection patterns play modulating roles in storm activity, linking polar and midlatitude climate. In addition, the tropics has been recognized as an important source for triggering teleconnections, and may also be subject to impacts of polar climate changes. Storms and teleconnections have demonstrated systematic variations, leading to alterations of feedback processes and, in turn, contributing to climate variability and change. This session will provide a venue to present progress and new ideas on extratropical and high-latitude storm activity, tropical or extratropical teleconnections with the polar regions, and associated physical feedback processes in the context of the changing polar climate, as well as resulting extreme weather events, ecosystem- and societal impacts.
