摘要
运用GRAPES数值预报模式产品与攀西地区6月日雨量进行相关分析,发现GRAPES模式的部分产品(如风场、温度场、比湿场、涡度场)的24h变量及02时垂直速度场与攀西地区日降水有很好的相关性,准确反映了该地区6月日降水的主要影响系统,可用于对GRAPES数值产品的解释应用中.通过建立MOS预报方程的试报结果分析,表明对该地区的面雨量预报具有一定的参考价值.
The correlation analysis was used for finding the relation between the products of GRAPES and the area-rainfall at the Panxi area in June,we find the better correlation between the fields of 24 hours increment of a part of product(such as the field of wind,the field of temperature,the field of Q,the field of vorticity,etc.)of GRAPES,the field of vertical speed at 2 o'clock of GRAPES and the area-rainfall in Panxi area.They reflects the main system in this area in June,the product of GRAPES may be used for interpretation and application.Through the analysis of the result of MOS forecasting equation,it is indicated that the prediction of Panxi area-rainfall.
