Comparative Experiments on Methods for Calculating Logarithmic Surface Pressure Gradient in Spherical Coordinates
-
摘要: 在192×96球面高斯格点上,我们用几种常用的数值计算方法,计算一个理想的地气系统的对数场面气压梯度,通过对比可以得出,在这样的网格点上,用样条函数方法计算对数场面气压梯度的结果比用谱方法(包括T21,T42,T63)的计算结果好。Abstract: With several kinds of numerical methods commonly used, the logarithmic surface pressure gradient of an ideal earth-atmosphere system is calculated on 192×96 Gaussian grid points Comparative experiments show that, on such grid points, calculations with the spline method are better than those with spectral methods including T21, T42 and T63.
