阿勒泰夏季大降水过程中高潜能场的时空变化特征分析

Time and Space Features of High Latent Energy Field in Summer Heavy Rain Process in Altai

以大降水过程中触发高潜能量释放的天气系统为背景条件,以高潜能场为起报信息,对40个大降水个例进行统计、分析和归纳,概括出阿勒泰夏季大降水过程中,高潜能场的时空变化特征,从中得出预报阿勒泰夏季大降水的新指标,进一步提高了大降水预报的准确率。

Based on the background condition of weather system which trigger high latent energy releasing in heavy rain process , made forecast using high latent energy field, this paper generalize the time and space features of high latent energy field in Altai during summer by means of statistic、analysis of fourty case of heavy rain. The important indexes of forecasting Altai during summer heavy rain were found, accuracy of forcasting heavy rain was improved better.
