Abstract

Abstract

The impact of TRMM/TMI surface rainfall rate (SRR) 4DVAR on numerical simulation of TC Danas (2001) is studied.Several numerical experiments are performed with mesoscale model MM5 to in vestigate the development of Danas from TC genesis to a typhoon.Under the dynamic constraint of MM5 model,the SRR data are assimilated directly in the initial meteorological field (18 km).The direct assimilation of SRR data with MM5 4DVAR is proved to be feasible,which not only incorporate as many observation data available as possible but also avoid the resultant error due to the twice cycles of assimilation (1DVAR+4DVAR).On the basis of adjusting the initial fields (SLP,temperature,humidity and soon),the direct assimilation of TRMM SRR improves the description of TC structure (such as warm core,vorticity and divergence) and the prediction of rainfall.As a result,the intensity and track of Danas are simulated successfully with TR M SRR assimilation.
