【摘要】 本文用两种工具对我们设计的一个大气环流模式及其差分格式作了较为严格的检验。首先,我们用检验球面模式的传统工具Rossby-Haurwitz波对简化的正压模式进行了检验,其效果与欧洲中心的结果极为一致。其次,我们发展了检验斜压初始方程模式的工具——非线性Haurwitz波,并对环流模式的框架部分作了检验,取得了令人满意的结果。更多还原

【Abstract】 In this paper, we test our difference scheme of a GCM by using two methods. First, we adopt the conventional Rossby-Haurwitz wave as the initial conditions to test the simplified barotropic model. The results are as good as that obtained by the barotropic model of ECMRWF. Second, we developed a nonlinear Haurwitz wave for the baroclinic primitive equations, then use it to test our GCM. The results of the tests are very encouraging.更多还原
