一种绘制地面天气图及要素场等值线方法
A Method for Drawing Surface Weather Chart and Contours of Meteorological Elements
【摘要】 采用位图作为天气符号绘制天气图 ,利用规则三角形网格法绘制等值线 ,通过 Visual C++6 .0软件编程 ,并在计算机上得到实现。结果表明 ,此方法绘制的天气图显示清晰 ,等值线分析准确、光滑 ,完全可以满足气象台站日常业务要求。
【Abstract】 A method using bitmap as weather symbol to draw surface weather chart and using regular triangle net to draw the contours of meteorological elements are introduced in this paper.The operational results of the programme developed under the Visual C ++ 6.0 software environment show that the surface charts drawed by the method are clear,and the contours are accurate and smooth.It can meet daily routine requirement of meteorological observatory.
