> MAIN TOPICS AND COURSES:
>
> Observations (Satellite instruments, in-situ and remote
> measurements of water
> vapour and chemical compounds, clouds in the UT/LS, data evaluation)
>
> Water vapour in the climate system (Role in the radiative
> processes, dynamical
> role in the mid-latitudes and in tropics
>
> Supersaturation processes and the generation of cirrrus clouds
>
> Processes determining the distribution of water vapour in the free
> atmosphere
> (long-range transport, coupling with convection, dehydration at the
> tropical
> tropopause)
>
> Modelling water vapour (parameterizations, transport, assimilation
> of water
> vapour data, future evolution under climate change)

> PURPOSE
>
> Water vapour is a key component of the climate system. It is the
> most potent
> greenhouse gas, and its condensed forms (liquid and ice) exert a
> profound
> influence on both incoming solar and outgoing infrared radiation.
> Climate models
> find that predictions of climate change are very sensitive to water
> vapour and
> cloud feedback: water vapour feedback alone doubles the effect of
> an increase in
> other greenhouse gases. But there is considerable uncertainty in these
> calculations: the water vapour feedback occurs mainly in the upper
> part of the
> troposphere where there is no physical link between water vapour and
> temperature. Climate models tend to suggest that the relative
> humidity of the
> upper troposphere will remain unchanged in a warmer world (so that
> the absolute
> humidity will increase) but since they do not represent explicitly
> the processes
> whereby water vapour gets to those altitudes this result is
> uncertain. A better
> understanding of the distribution of atmospheric humidity, and the
> processes
> that control it above the boundary layer, is therefore of primary
> importance in
> climate research. Water vapour is also, by its presence or its
> absence, an
> important component of atmospheric chemistry. The fact that the
> stratosphere is
> very dry, with only 4 to 6 water molecules per million, is
> essential in the
> ozone chemistry. Although modelling of the future evolution of the
> stratosphere
> is still in its infancy, variations of vapour water are likely to be a
> determining factor and the available records already display signs
> of a recent
> evolution. The entry of water vapour in the stratosphere is
> governed by
> processes occuring in the region of the tropical tropopause which
> are strongly
> coupled with tropical convection. The goal of the school is to
> present a
> comprehensive overview of the state_of-the-art and recent
> progresses in the
> observation, assimilation and understanding of the distribution of
> atmospheric
> water vapour and its role in the climate system.
>
> The main lecture courses will be complemented by tutorials,
> sessions of questions
> and anwers, theme discussions and poster presentations.
> The course is aimed primarely at PhD students, postdocs and other
> young scientists
> wishing to broaden and deepen their knowledge or to identify new
> research
> opportunities.
>
> Fellowships are available to cover local expenses. Some limited
> support will be provided
> for travel costs, in particular for applicants in the US and India.
> All applicants are required to send a CV mentioning their
> background and those
> requiring support must send a letter describing their need of
> support and
> how the school would benefit their research program.
