Abstract

Based on the multiple meteorological, hydrological intensify observations, and the NCEP reanalysis data, combined with the simulation and diagnosis data of meso\|scale numeric model of AREM, the water vapor features of two unique cyclone, the typhoon Bilis and Sepat which inducing heavy rainfall in the Hunan province are analyzed and some comparisons are conducted. The results show that, both of cyclones have two main water vapor channels, one is from south linkingwith the west\|south monsoon, and the other is from north linkingwith the cyclone′s low\|pressure circulation. In addition, their rain water mainly originates from the convergence of the lower levels, and is transported to the middle and high levels by local ascending airflows. However, it is noted that the water vapor flux in the Sepat′s heavy rain areas has stronger intensity than that of Bilis. Although with the weaker convergence of the water vapor flux and thinner convergent depth, Sepat′s lifetime is longer, total rainfall is larger and coveringarea is broader, since it has relatively stronger inner strength, and the steady wind shear in the south part of the cyclone′s center. On the otherhand, the main water vapor path of Bilis is much more southerly,the moisture convergence andthe interaction of the South China Sea monsoonarestronger than those of Sepat′s, its rain intensity in some areas and in certain periods is much more stronger.
