西藏气象指数通用计算系统

Universal Service Platform for Common Meteorological Indexes in Tibet

利用人机交互方式定义气象指数计算公式,设计了西藏地区常用气象指数计算系统。该系统在统一的操作界面上定义和读取输入气象数据,包括数值预报、实况数据、预报产品等数据及站号、经度、纬度和时间信息,将相应的数据以浮点数代入公式,并支持加、减、乘、除、乘方等数学运算符,三角对数、绝对值等数学函数,且、或、否等逻辑函数,≥、>、≤、<、=等判断运算符及自定义的分段函数,能够完成多项气象指数的计算,数据均以通用的MICPAS格式交互存储,在统一的平台上管理气象指数及产品制作,无需预报和服务人员编程即可实现新的气象指数。

Using the man-machine interactive definition of meteorological indexes,a universal service system of common weather indexes in Tibet is devised.The input meteorological data,including numerical weather prediction,weather reality data,forecast products,station number,longitude,latitude,and time information,can be defined and read in a unified user interface.The corresponding data put into the formula in the form of the number of floating points to complete the calculation of meteorological indices.The data are stored interactively with universal MICPAS format,and weather indexes and service production are administrated under a uniform platform.Weather forecasting and service staff can provide new weather index service without programming.
