Dear colleagues,

On behalf of the conveners, I would like to invite you to submit abstracts
to session ST10: "Space weather and space climate: coupling processes from
the Sun to the Earth" at the Annual Meeting of Asia and Oceania
Geosciences Society (AOGS-2010), to be held from 5 to 9 July 2010 in
Hyderabad, India. Below is the description of the session. The deadline
for abstract submission is 1 March.

Best wishes,

ST10. Space weather and space climate: coupling processes from the Sun to
the Earth

The Sun, its extended corona, the interplanetary space, the Earth's
magnetosphere, ionosphere, middle and low atmosphere, are all parts of a
complex system - the heliosphere. Various manifestations of solar activity
cause disturbances known as space weather effects in the interplanetary
space, near-Earth environment, and all the Earth's "spheres. Long-term
variations in the frequency, intensity and relative importance of the
manifestations of solar activity are due to the slow changes in the output
of the solar dynamo, and they define space climate. Space climate governs
long-term variations in geomagnetic activity and is the primary natural
driver of terrestrial climate. To understand how the variable solar
activity affects the Earth's environment, geomagnetic activity and climate
on both short and long time scales, we need to understand the origins of
solar activity itself and its different manifestations, as well as the
sequence of coupling processes linking various parts of the system. This
session provides a forum to discuss the chain of processes and relations
from the Sun to the Earth's surface: the origin and long-term and
short-term evolution of solar activity, initiation and temporal variations
in solar flares, CMEs, coronal holes, the solar wind and its interaction
with the terrestrial magnetosphere, the ionosphere and its connection to
the neutral dominated regions below and the plasma dominated regions
above, the stratosphere, its variations due to the changing solar activity
and its interactions with the underlying troposphere, and the mechanisms
of solar influences on the lower atmosphere on different time-scales.
Particularly welcome are papers highlighting the coupling processes
between the different domains in this complex system.
