Session Description
Storms bring extreme weather to the arctic and sub-arctic regions, and
are directly responsible for 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 sub-arctic
regions 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 sub-arctic regions may also strengthen
synoptic-scale air-ice-ocean interactions, thereby impacting climate
variability and change. This session will include studies on the arctic
and sub-arctic storm activity, including its interannual- and
decadal-scale variability and long-term changes. Specifically, the
following topics fit this session: detection of interannual-to-decadal
variability and long-term changes of storm activity in observations and
in model simulations; exploration of underlying physical mechanisms,
examination of anthropogenic forcing impacts on the storm activity;
comparison of storm identification and tracking methodologies;
statistical analysis and model simulation of extreme weather associated
with storm events; and 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 sub-arctic regions are also welcome.
