A051: Extratropical and High-latitude Storm Tracks, Circulation Dynamics, and Extreme Events in the Context of Rapidly Changing Arctic and Antarctic Climate
Conveners: Xiangdong Zhang, Kent Moore, and James E. Overland
Storm tracks and large-scale atmospheric circulation are prominent dynamic drivers for daily-to-decadal climate variability and can interplay with anthropogenic forcing to contribute to long-term climate change in the extratropics and high-latitudes. They have demonstrated systematic changes along with the rapidly changing polar climate, leading to alterations of feedback processes and contributing to anomalous variability and changes of climate. Intense storms, amplified jet streams/Rossby waves, and weakened stratospheric polar vortex often cause 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. This session provides a venue to present progress on extratropical and high-latitude storm tracks, circulation dynamics, and their role in teleconnections linking extratropics/tropics with the polar regions, resulting extreme events, and underlying physical processes (e.g., stratosphere-troposphere coupling, Rossby waves and jet streams, wave-mean flow interactions), as well as associated ecosystem- and societal impacts.
