925hPa标准等压面资料在强对流天气预报中的应用

Application of Data at 925hPa Standard Pressure Level to Severe Convective Weather Forecasting

从１９９１年第四季度开始，高空报（ＴＴＡＡ）中增加了９２５ｈＰａ标准等压面资料。京津冀中尺度气象试验基地１９９２年夏季的试用结果表明，９２５ｈＰａ等压面资料为预报强对流天气提供了非常有用的信息。

ata at 925hpa standard prssure level is included in TTAA synoptic code since october,1991. According to the summer experiment in 1992 at the Beijing-Tianjin-Hebei Disastrous Weather Experiment Base Centre,it was indicated that the data at 925hpa standard pressure level is very useful for severe convective weather forecasting.
