ABSTRACT
The Marine Meteorology Division of the Naval Research Laboratory,
Monterey, California (NRL MRY) has been engaged in the development
and testing of mesoscale numerical weather prediction systems for
over 25 years. In particular, NRL MRY has developed the Coupled Ocean/Atmosphere
Mesoscale Prediction System (COAMPS) for mesoscale, short-term (24-72
hour) applications. In addition to the development and testing, NRL MRY
has transitioned COAMPS to operations at the Fleet Numerical Meteorology
and Oceanography Center (FNMOC), and for operations at Navy regional centers.
NRL MRY is now actively engaged in improving COAMPS. One significant
improvement that is nearly complete is the NRL Atmospheric Variational
Data Assimilation System (NAVDAS), a 3-dimensional variational analysis.
Our research on COAMPS includes improvements to the explicit moist physics,
initialization of the position and structure of tropical cyclones, implementation
of moving nested grids within the context of Message-Passing-Interface
(MPI) code, air-ocean coupling, mesoscale validation, incorporation of
aerosols and the study of their effects on moist processes, and studies
of mountain wave dynamics and fetch-limited and orographic flows. This
presentation will provide an overview of the basic components of
COAMPS, examples of its use, the methods used to evaluate its performance,
and an outline of the advances planned.
