Typhoon
Rusa (2002) has devastated the east coast of the Korean peninsula with
heavy rainfall
(24 hr accumulated rainfall of ~860 mm). The heavy rainfall was
associated with topography
and other synoptic conditions. A set of experiments were performed, by
employing an
OSSEs strategy and a mesoscale model (MM5), to investigate potential
impact of dropwindsondes
on improving typhoon forecasts in track, intensity and rainfall.
Discussions on the
usefulness of simulated dropwindsonde data will be provided in terms of
data distributions and
various microphysical schemes. Implications of our results on the Asian
THORPEX will be also
discussed.
