摘　　要：通过对逐时六要素自动气象站资料的二次开发,利用逐时六要素气象资料,对一些物理量公式进行计算机编程计算,自动生成逐时的水汽压、相对湿度、本站气压、位温及14:00浮力共5个物理量产品,并把它保存为能被M icaps系统调阅的第三类数据格式文件。通过对2009年发生在南平市的一次强对流天气过程分析表明,应用这些新增加的物理量产品,将提高对中小尺度系统,特别是强对流天气的短时监测、预报和预警能力。Through the secondary development of the six-hourly automatic weather station data elements,using six elements of hourly weather data,some physical quantities of computer programming formula were calculated to automatically generate five physical quantities buoyancy products（the vapor pressure,relative humidity,air pressure site,bit temperature and 14：00 flotage）.And the products of these physical quantities can be saved as Micaps system access to the third category of data files.A strong convective weather process occurred in Nanping in 2009 was analyzed.The analysis showed that the application of these additional physical quantity products would improve the small and medium-scale systems,particularly short-term convective weather monitoring,forecasting and early warning capability.
