of the project: Dr. Ming-Dean Cheng
team was formed in 1994. The works of the data assimilation is one
of the most important
components in CWB's NWP system. The geographical location
of Taiwan is on the southeastern
edge of Asia continent. Since the conventional
sounding are somewhat limited by the land surface,
the limited area forecast
model, which is centered on Taiwan, faces the imbalance distribution of
conventional observation. Therefore, works of the data assimilation team are
on the assimilating of the satellite data.
assimilation system for the Global forecast system has been upgraded to 3DVAR
assimilated data include the conventional soundings, aircraft reports, SSM/I
surface wind, NSCAT surface wind, Satellite cloud-track wind, satellite
observed radiance and
synoptic surface observations. The 3DVAR for the
Non-hydrostatic Forecast System is also
under development and will be operation soon.
tasks will be
focused on the assimilation of the wide-band radar data and new
developed remote sensing
observations such as new satellite observed radiance
(NOAA16…) AND the meteorological GPS.
