摘要
利用EC细网格数值预报产品对2015年3月出现在抚顺章党站的2次一般性降水过程进行诊断分析和预报释用,结果表明：EC细网格预报的累积降水量大小不能作为判断未来降水量的直接依据,应根据EC细网格预报出的其他物理量综合判断,即850 h Pa层面以下存在比较大的比湿、较长的降水持续期间、低层925~700 h Pa持续的上升运动、较强的850 h Pa低空急流。
Based on EC fine grid NWP products,two general precipitation weather process in Fushun appeared During March 2015 were diagnostic analyzed.The results showed that quantitative precipitation prediction of EC fine grid could not be as a criterion of the forecast of future rainfall, making a comprehensive judgment should be combined with other physical quantities of EC fine grid at the same time.First of all,specific humidity below 850 hpa level there was larger.Second ,there was a long duration of rainfall.Third, there was continuous upward movement in 925-700 hpa airspace.Forth, there was the strong low-level jet in 850 hpa.
