Job Duties
A lead developer in the continuing development of the ATEC/4DWX
RTFDDA model system. Working with project leaders (Tom Warner
and Scott Swerdlin) to define the scope, task and direction
of the model development. A chief developer and coordinator for
the developments of new model components, improvements on the
existing components and real time model applications in existing
and
new DoD, civil and international projects.
A project manager for the AirDat-NCAR modeling project to research
and maximize the impact of the TAMDAR data in mesoscale NWP and
data assimilation.
Professional Research Areas
Mesoscale meteorological data assimilation and ensemble forecasts;
Multiscale interaction of regional and local scale weather processes;
Cloud physics and their impact on different mesoscale severe weather
processes including convective storms, hurricane and other oceanic
cyclones and weather modification; Physical parameterizations in
mesoscale NWP models for microphysics, convective, eddy mixing;
PBL and LSM; Weather observations from conventional and remote-sensing
platforms; Application of computer sciences and linux-cluster in
weather research and operation
