主 题:AIRS data assimilation temperature profile moisture profile hurricane forecast WRF 3DVAR
摘 要:Atmospheric InfraRed Sounder (AIRS) measurements are a valuable supplement to current observational data,especially over the oceans where conventional data are *** this study,two types of AIRS-retrieved temperature and moisture profiles,the AIRS Science Team product (SciSup) and the single field-of-view (SFOV) research product,were evaluated with European Centre for Medium-Range Weather Forecasts (ECMWF) analysis data over the Atlantic Ocean during Hurricane Ike (2008) and Hurricane Irene (2011).The evaluation results showed that both types of AIRS profiles agreed well with the ECMWF analysis,especially between 200 hPa and 700 *** average standard deviation of both temperature profiles was approximately 1 K under 200 hPa,where the mean AIRS temperature profile from the AIRS SciSup retrievals was slightly colder than that from the AIRS SFOV *** mean SciSup moisture profile was slightly drier than that from the SFOV in the mid troposphere.A series of data assimilation and forecast experiments was then conducted with the Advanced Research version of the Weather Research and Forecasting (WRF) model and its three-dimensional variational (3DVAR) data assimilation system for hurricanes Ike and *** results showed an improvement in the hurricane track due to the assimilation of AIRS clear-sky temperature profiles in the hurricane *** terms of total precipitable water and rainfall forecasts,the hurricane moisture environment was found to be affected by the AIRS sounding ***,improving hurricane intensity forecasts through assimilating AIRS profiles remains a challenge for further study.
