地基微波辐射计资料同化对一次特大暴雨过程影响的数值试验研究

Numerical Study of an Excessive Heavy Rain Event by Assimilating Humidity Profiles Retrieved From Ground-based Microwave Radiometers

摘要: 基于暴雨中尺度数值预报模式AREMv2.3和三维变分同化系统GRAPES-3DVAR,以2008年7月22日08时至23日08时发生在我国东部地区的一次特大暴雨过程为例,研究了荆州、咸宁、常德3部地基微波辐射计反演的相对湿度廓线资料同化对降水预报的

Abstract: Based on the mesoscale numerical model AREMv2.3 and GRAPES-3DVAR data assimilation system,an experiment was carried out to study the impact on the precipitation forecast for a heavy rain event occurred in the Eas
