微波温湿遥感资料在台风路径模拟中的同化试验
The experimental study of assimilating microwave temperature and humidity remote sensing data in typhoon numerical simulation
摘要
Abstract
Based on the WRF model and 3DVar assimilation method,the AMSU-A data for atmospheric temperature detection and MHS data for atmospheric temperature humidity of NOAA satellites were assimilated in the event of the super typhoon "soudelor" (Number 13,2015),which aims to investigate the effects of assimilating different remote sensing data on typhoon track's simulation.The results demonstrated,the improvement of typhoon track simulation accuracy after assimilating AMSU-A data is larger than that after assimilating MHS data.Under different control experiments,the average track error of typhoon is decreased by 49km at most by assimilating AMSU-A data,while the average track error of typhoon is decreased by 29km at most by assimilating MHS data.the effectiveness of assimilating a combined data set include AMSU-A and MHS data on the improvement of the typhoon track was not better than that of assimilating separate data..The intensity and range of adjustment on the initial field by assimilating AMSU-A data is larger than that by assimilating MHS data.After the model's integration for a period of time,the adjustment intensity on the physical field by assimilating two types of data became closer.The adjustment of the physical field by assimilating microwave remote sensing data well correspond to the adjustment on the typhoon track's simulation.关键词
