摘要
本文用样条插值进行了高度、温度、地面气压等要素场的客观分析试验,取得了良好的结果。本文绘出二测站的三次插值关系式,并以此为基础把二维分析问题化为有限多个一线问题,计算简单稳定,实用方便。
By using the spline interpolation,objective analyses of geopotential,temperature and surface pressure fields are tested and good results obtained.A cubic polynomal for interpolations is given for two adjacent stations by which the problem of two-dimensional analysis can be reduced to a number of one-dimensional interpolations.The algorithm is simple and stable,therefore suitable for practical use.
