摘要
在分析WRF模式对初始资料需求的基础上,对比分析LAPS资料和NCEP资料的异同,设计LAPS资料应用到WRF模式的流程,实现资料的格式转换及其与模式的衔接。基于这两种资料,以2008年6月12—13日广西大暴雨为例进行模拟试验,并用TS评分和SAL定量评估方法对模拟的降水结果进行检验。结果表明,与NCEP资料相比,LAPS资料可提高暴雨预报的精度,尤其对暴雨落区的预报。
The application of LAPS data to WRF model is studied. Based on the analysis of the initial field required of WRF and the similarities and differences between LAPS and NCEP data, the format conversion of LAPS data is resolved, and the flow of the application is designed in this paper. In order to evaluate the validity of applying LAPS data to WRF, a heavy rain in Guangxi on June 12--13, 2008 is simulated by using the LAPS and NCEP data. Both the TS score and SAL measurements are used for the verification of quantitative precipitation forecasts. The results indicate that the LAPS data is efficient in improving the precision of QPFs, especially the location of precipitation, compared with the NCEP data.
