Role of mixed precipitating cloud systems on the typhoon rainfall
Description (Dublin Core)
L-band wind profiler data are utilized to diagnose the vertical structure of
the typhoon precipitating cloud systems in Taiwan. For several typhoons, a
pronounced bright band (BB) around 5 km is commonly observed from the
observation. Since strong convection within typhoon circulation may disturb
and/or disrupt the melting layer, the BB shall not appear persistently.
Hence, an understanding of the vertical structure of the BB region is
important because it holds extensive hydrometeors information on the type of
precipitation and its variability. Wind profiler observational results
suggest that the mixture of convective and stratiform (embedded type) clouds
are mostly associated with typhoons. In the case of one typhoon, BB is
appeared around 5.5 km with embedded precipitation and also BB height of 1 km
higher than ordinary showery precipitation. This is evident from the
long-term observations of wind profiler and Tropical Rainfall Measuring
Mission. The Doppler velocity profiles show hydrometers (ice/snow) at 6 km
but liquid below 5 km for typhoons and 4 km for showery precipitation. In
the BB region the melting particles accelerations of 5.8 ms<sup>−1</sup> km<sup>−1</sup> and
3.2 ms<sup>−1</sup> km<sup>−1</sup> are observed for typhoon and showery precipitation,
respectively.
