You are invited to submit an abstract to the following special session
at this year's American Geophysical Union (AGU) Fall Meeting:

Session A 24: Northern Extratropical and Arctic Storm Activity:
Variability, Long-Term Changes, and Impacts

Session Description:
Storms bring extreme weather to the northern extratropical and arctic
regions and are directly responsible for the major high-wind events,
coastal flooding and erosion, and rapid temperature changes. Poleward
shift of storm track and intensification of storm activity in the Arctic
and northern high-latitudes have recently become apparent in data-based
studies. These changes in storminess, together with the shrinkage of sea
ice observed in recent decades and projected for the future, point to
increased risk of coastal flooding and erosion. Furthermore, the
intensified storm activity in the Arctic and northern high-latitudes may
also strengthen synoptic-scale air-ice-ocean interactions, thereby
impacting climate variability and change. This session will provide a
platform to present recent progress in the understanding of the northern
extratropical and arctic storm activity, including its interannual- and
decadal-scale variability and long-term changes. Specifically, the
following topics fit this session: (1) detection of
interannual-to-decadal variability and long-term changes of storm
activity in observations and in model simulations; (2) exploration of
underlying physical mechanisms, examination of anthropogenic forcing
impacts on the storm activity; (3) comparison of storm identification
and tracking methodologies; (4) statistical analysis and model
simulation of extreme weather associated with storm events; and (5)
investigation of storm impacts on air-ice-sea interactions and the
associated role in climate variability and change. Studies of impacts of
storm activity on coastlines, ecosystem and society in the Arctic and
northern high-latitude regions are also welcome.
