Assimilation Experiments with Dual-Doppler Wind Field Retrieval Data
摘要
Abstract
Three dimensional wind field are obtained in Cartesian coordinate with Hefei and Maanshan dual-Doppler radars united observations by means of a Multiple-Doppler Synthesis and Continuity Ad-justment Technique(MUSCAT). The retrieval wind field is assimilated in mesoscale numerical model ARPS (advanced regional prediction system), developed by Center for Analysis and Prediction of Storm (CAPS), and ARPS Data Analysis System(ADAS). The results show that the retrieval wind field can improve effectively short-time simulation field, especially wind field. For the condition of humidity without reflectivity information, however, there are some differences between the predicted and observed 3 h precipitation as a result of the humidity field improved less.关键词
