Abstract
There are two topics involved in this
project:
(1) A regional climatology model is
proposed for quantitative forecast of
typhoon rainfall. The model is for river
basins where there are too few historical
hourly rainfall records of the rainfall
stations to develop the single-station
climatology model, such as the Wu Creek
Basin.This model is a statistical one, it is
therefore suitable for estmating the case
while rainfall intensity is only affected by
typhoon, such as Typhoon Herb(1996).
This paper presents preliminary results
of airflow/mountain interaction and
associated spatial rainfall pattern simulation
study by a numerical model. 3D wind
fields for uniform flow over smoothed
topography of Taiwan are constructed using
the North Carolina State University
Geophysical Fluid Dynamics Model
(NCSU/GFDM). The terrain-induced
precipitation adopts the seeder-feeder
parameterization model.
