摘要
采用美国国家环境预报中心高空间分辨率再分析海温资料和中国国家海洋环境预报中心提供的逐小时全球高时间分辨率海温数据,通过WRF模式对2018年10号台风“安比”(1810)进行数值模拟,结合台风动力和热力条件分析结果表明:海温分布与位涡强度具有良好的一致性;海温通过影响台风内部垂直运动带来的潜热释放决定对台风强度的改变,高分辨率的海温数据对台风数值模拟有一定影响。
Based on the sea surface temperature(SST)reanalysis data with high spatial resolution of the National Centers for Environmental Prediction and the hourly SST data with global coverage of the National Marine Environmental Forecasting Center,the Weather Research and Forecasting model is used to simulate typhoon"Ampil"(1810)in this paper.Taking the analysis results of typhoon dynamic and thermal conditions into consideration,it is found that the SST distribution is in good agreement with the intensity of the potential vorticity,and SST determines the variation of typhoon intensity by affecting the latent heat release caused by the vertical movement within the typhoon.Therefore,high-resolution SST data has a certain impact on the numerical simulation of typhoon.
