GRAPES与MM5产品业务应用质量对比

分别以GRAPES和MM5为核心建立中尺度数值预报业务系统,并对2006年6～8月温度和降水预报产品业务应用效果进行严格的检验。结果表明:GRAPES和MM5对黑龙江省都具有较强的预报能力,温度预报两者相当,24h降水预报GRAPES总体好于MM5,48h降水预报MM5总体好于GRAPES。两个中尺度数值预报业务系统的产品,对实现精细化预报有重要的作用,可以作为加工预报产品的基础。

Quality Analysis of Prediction in Application of GRAPES and MM5

Two limited regional mesoscale numerical model systems have been set up on the basis of GRAPES and MM5. Quality analysis of theirs are examined in application of forecasting temperature and precipitation of summer 2006. The results indicate: GRAPES and MM5 have great ability on predict. The temperature prediction of GRAPES bears comparison to that of MM5. The 0~24 h precipitaion prediction effect of GRAPES is superior to that of MM5, the 24~48 h of GRAPES is inferion to that of MM5. The productions of GRAPES and MM5 can be the basis of high resolution and high precision precipitaion.
