常规资料获取中尺度信息的一种简便方案

基于Ｂａｒｎｅｓ滤波原理，利用低通滤场的连续性特征，设计了一种从观测资料中提取中尺度气象信息的简便方案。利用该方案，可独立地获得观测站网和规则网格点上的中尺度气象信息，为基层气象台站进行中分析提供了方便。该方案与过去方案相比，具有计算量小，速度快，程序设计简单，计算精度高等优点，尤其适合基层台站使用。

A Simple Technique of Separation of Mesoscale Form from Meteorological Data

Based on both Barnes' filter theory and continuity of low-pass filter,a simple technique is designed separating mesoscale information from meteorological data. With this technique, stationand grid values of mesoscale bandpass filter can be independently obtained from observational data.Futhermore,the technique has higher precise and quicker velocity.
