摘要
研究各重现期广西冬季最低气温的小网格气候分析方法。采用网格距为 0 .1× 0 .1经纬度的小网格 ,从地理信息系统 GIS中读取海拔高度资料 ,用回归分析方法求气候方程 ,利用 Gr ADS绘图系统提供的 oacres内部插值函数求取格点余差插值 ,利用改进的 Gr
Emphasis of this study is on the climate analysis by way of small grille for the minimum winter temperature in Guangxi during reoccurrence period. The small geographic coordinate grille with the space of 0.1 x 0.1 and regression analysis are adopted, with the aid of elevation information read from GIS, to work out the climate equation. The oacres internal interpolation function provided by GrADS drafting system is utilized to calculate the increment interpolation of each grille point for drafting a small grille climate analysis chart, using the improved GrADS drafting system.
