| 摘 要： | 用EC850hPa温度数值预报格点值为参考做短中期的最高(低)温度预报是预报员常用的温度预报方法,本文提出了划分季节、划分有无降水和划分850hPa变温3种最高(低)温度PP法修正预报方案,并进行比较,找出最优方法,使最高(低)温度的预报精确度在原来的基础上有所提高。

| Abstract: | It is a frequently used method for weather forecasters to use temperature numerical forecast grid value of EC 850hpa as reference data to predict short-term and medium-term maximum and minimum temperature.Three kinds of maximum and minimum temperature PP method modification forecasting projects according to seasons, precipitation and 850hpa temperature variation, were put forward.Comparison analysis of the three projects was done to find out the best method in order to improve the forecasting precision of maximum and minimum temperature on the original basis. |
