COMPARATIVE ANALYSIS OF TROPICAL CYCLONE'S STRUCTURE BETWEEN ECMWF HIGH RESOLUTION REANALYSIS DATA AND BOGUS MODEL IN 2015
摘要
Abstract
The description of tropical cyclone structure is very vital to the tropical cyclone (TC) numerical simulation,and the intensity and the internal structure of TC simulated are still not satisfactorily understood.Sometimes,the structure of Bogus model couldnot conform to the actual situation.Furthermore,simulation results are still not satisfactory with low resolution reanalysis data directly used.Therefore,high resolution reanalysis data are required for describing TC fine structure.In this research,the numbered TCs in the Northwest Pacific Ocean are classified and analyzed according to 0.125 degree high-resolution ECMWF reanalysis data.In 2015,overall,ECMWF has a good performance in the simulation of TCs compared with Bogus.No matter how strong the TC is,its height,temperature,humidity and wind field depicted by ECMWF are close to the actual state.Moreover,not only ECMWF reanalysis data can characterize the fine and asymmetric structure of TCs,but also its resolution matches the numerical model,which is helpful in prediction and assimilation analysis in future,so that it can be applied to the numerical forecast of TCs in place of Bogus.关键词
