Objective
Objectives :
This project aims to advance our understanding and
process modelling of gravity
waves in the atmosphere, and to improve the quality of
gravity wave parametrizations
for general circulation models of the atmosphere.
Brief Description of the Research Project :
The project is a combined effort by researchers with
expertise in the observation of
gravity waves, in global circulation models (GCMs) of the
atmosphere, in theoretical
process and data studies of gravity wave behaviour, and
in parametrization
development.
In order to improve our understanding of observed gravity
wave spectra, and to help
bridge the gap between observational data and gravity
wave parametrizations for
GCMs, a new, "intermediate" level of process modelling,
based on stochastic
hypotheses, e.g. about spectral phase information, will
be developed and compared
with data. The resulting "intermediate models" will, for
the first time, incorporate both
monochromatic (orographic) and broadband (nonorographic)
waves in a way that
allows for their mutual interaction.
New and improved gravity wave parametrizations for GCMs
that build on the above
will be developed using an intermediate model as a test-bench in addition to direct
comparisons with data.
A programme of carefully controlled GCM experiments, in
several GCMs, will test
the most promising parametrization(s) together with the
spectral parametrization
proposed by Hines.
An innovative top boundary condition for GCMs will be
developed and tested. This
exploits recently-clarified dynamical principles
(relating to so-called "downward
control") to avoid the need to simulate the mesosphere
while preserving to good
approximation the mesospheric, gravity-wave-dominated
contribution to the wave-driven pumping of chemical constituents including
greenhouse gases.
