摘　　要：利用台风凤凰期间NCEP 1°×1°资料,介绍一种非对应格点数据的合成处理方法,用GRADS绘制了台风3天12个时次的平均垂直速度剖面图。着重介绍了具体实现过程和GRADS脚本程序原代码的编写。结果表明,运用这种方法处理的图像比原图像更清楚的反映出台风的内部结构。Using the 1°×1°NCEP data collected during the TC Fenghuang, an integrated method to process the non-corresponding grid data was introduced. Using the GRADS , a graph of average vertical velocity of the typhoon every two hours in 3 days was produced. It focuses on the specific processing procedure and the compilation of source code of GRADS script. It is found that the graph compiled by this method could reflect the internal structure of typhoon more clearly than the original graph.
