Abstract:
By using conventional meteorological, satellite, radar, regional automatic weather station, and NCEP reanalysis data, the characteristics of precipitation over the northeastern Fujian Province induced by the typhoon Morakot are studied. The results show that Morakot had an obvious hollow structure; the favorable environmental condition, the continuous impact of convective cells in the spiral cloud band, and the slow movement of the typhoon were the main reasons for the heavy rainfall, while the increasing role of topography was also evident. Through comparing the intensity of basic reflectivity factor and the hourtohour rainfall of regional automatic weather stations, the precipitation rate features of convective cells in the spiral cloud band are discussed, which is of reference value for the shortterm and nowcasting forecast of typhoon heavy rainfall.
