SUB: CALL FOR ABSTRACTS in AOGS-2011 Session ST08  on "Atmospheric
Coupling Processes in the Sun-Earth System"

Dear Colleagues,

We would like to bring to your attention the session ST08 on "Atmospheric
Coupling Processes in the Sun-Earth System" in the 8th AOGS Assembly
scheduled to be held at Taipei during 8 - 12 August 2011.  Detailed
description of the session is given below.  Please consider submitting an
abstract to this session on your work that relates to any of the coupling
processes between various regions in the Sun-Earth domain (namely, solar
wind - magnetosphere coupling, magnetosphere-ionosphere coupling,
ionosphere-thermosphere coupling, high-to-low-latitude coupling, including
vertical coupling processes of terrestrial atmospheres).  I expect that
there will be lively discussions on the various aspects of coupling
processes in the sun-earth domain in this session.

Last date for submission of an abstract is: 15 March 2011.
To submit an abstract visit: http://www.asiaoceania.org/

Thank you,
-- D. Pallamraju, C. Lin, G. Lu

The Earth’s atmospheric regions are intricately coupled to one another via
dynamical, chemical, and electrodynamical processes in addition to the
processes that exist due to the solar & interplanetary effects. The
coupling and the energy exchange in the Sun-Earth system can be
characterized into short-scales (hours to days, e.g., the time scale of
space weather), medium-scales (seasonal, annual, etc.), and long-scales
(solar cycle). Several new observations in the recent past have revealed a
close connection between the dynamical processes in the lower atmosphere
with that of the temporal and spatial variability in the thermosphere and
the ionosphere, such as the existence of diurnal eastward modes 3 or 4 in
the plasma densities being closely associated with the convective
structures in the low-altitude atmosphere, stratospheric sudden warming
events in high-latitudes showing enhanced features in neutral and ionized
parameters in the upper atmosphere at low latitudes, and propagation of
waves from high- to low-latitudes, especially during space weather events.

We solicit papers for presentation in this Special Issue on the
“Atmospheric Coupling Processes in the Sun-Earth System” that specifically
deal with the coupling processes or coupled interactions in the Sun-Earth
system. That is, those works that highlight how the variability in one
latitude /altitude/ region is coupled with the variability in other
location(s)/region(s). These include coupling processes in the lower-upper
atmosphere, magnetosphere-ionosphere, high-to-low latitude, Solar-wind /
interplanetary medium to the magnetosphere, in addition to neutral –
plasma coupling processes. Realizing the importance of these coupling
processes global scale observational campaigns have been carried out under
the auspices of major international programs such as, the Climate and
Weather of the Sun-Earth System (CAWSES) and the International
Heliophysical Year (IHY), and several new insights are emerging from these
experiments as well. We welcome papers that deal with experiments,
observations, modeling, and data analysis that advance our understanding
of the coupling processes within the domain of the Sun-Earth system.

Last date for submission of an abstract is: 15 March 2011.
