The International Association of Meteorology and Atmospheric Sciences
(IAMAS), the International Association for the Physical Sciences of the
Oceans (IAPSO), and the International Association for the Cryospheric
Sciences (IACS) invite the international atmospheric, oceanographic and
cryospheric research community to MOCA-09, their Joint Assembly, to be
held 19 - 24 July 2009 in Montreal, Quebec, Canada
(http://www.moca-09.org). Abstracts are now being accepted for the
session "High Latitude Terrestrial Processes, Hydrology, and
Interactions with the Atmosphere." The abstract submission deadline is
Friday, 23 January 2009.

In high latitudes, the state of the land surface snow, ice, and water
resources are strongly controlled by complex interactive processes that
govern exchange between the climate, snow, lake ice, permafrost and
hydrology. These processes are subject to intense investigation as part
of the International Polar Year studies of freshwater supply and cold
regions processes. Interactions such as those processes mediating
climate, snow accumulation, snowmelt, sublimation, soil moisture, soil
thermodynamics, evaporation, and vegetation are of particular interest.
In order to consider future changes in hydrology and water resources due
to anthropogenic climate change it is necessary to understand these
processes. However, the nature of these interactions, and our ability to
model the relevant processes, are currently very limited. It is expected
that both natural climate variability and anthropogenic climate change
will result in significant changes to the state of high latitude
cryosphere and hydrology, however, due to the complex processes and
their cumulative effects it is difficult to predict with confidence what
direction and with what celerity these changes will occur.

This symposium will address these issues by bringing together experts in
the fields of cold regions hydrology, snow and ice and land surface
atmosphere interactions in order to discuss important issues and
advances in our understanding of high latitude terrestrial processes,
hydrology and the interactions between these processes and the
atmosphere.

Contributions are solicited on, but not limited to, the following:
- The interactions between surface, snow and atmospheric processes in
high latitudes,
- Snow processes and hydrology,
- The effects of changing arctic vegetation on land surface processes,
snow, hydrology and the atmosphere,
- The effects of climate change on high latitude hydrometeorological
processes,
- The ability of existing hydrological and land-surface models to
consider the complex interactions between land, snow, ice, hydrology
and atmospheres, and
- The ability of these models to consider the impact
of climate change on high latitude hydrological systems.

The deadline for this and all other sessions is Friday, 23 January 2009.
