摘要
Based on air-sea observations and reanalysis data,the numerical simulation and diagnostic analysis of typical Atlantic TC cases during 2010-2015 were carried out,and the influence of thermodynamic factors in air-sea exchange and atmospheric environment field on TC intensity was quantitatively calculated.TC was considered as a cylinder with a minimum pressure as the center and a radius of 300 km extending from sea level to 100 hPa,and the input and output of heat at each boundary of TC were quantitatively calculated.In order to understand the heat contribution of Atlantic TC during its development,the heat input at each boundary of 18 Atlantic TC cases was analyzed to study the main heat sources promoting TC strengthening.The results show that the heat directly from the atmosphere was the main source of heat during TC development.Due to the errors in the selection and calculation of data,one of Atlantic TC cases was selected for simulation verification at last,and the simulation results reveal that the simulated TC was in good agreement with the actual observed TC.
