The non - local turbulence parameterization , i . e . , transilient theory was used in the host model mm4 to simulate the turbulent activities of the atmosphere 在中尺度区域模式mm4的基础上对其中的湍流参数化方法作了改进，尝试用非局地闭合方法代替局地
2.
Results of comparison indicate that although some oversea study of the transilient theory succeeded in a degree , if the transilient theory is to be used in model mm4 , substantial improvement of the expression of the vertical mixing potential is necessary , or an empirical filter should be applied to ameliorate the result of forecasting 比较的结果证明，非局地方法若要应用于实际预报，还需要作较大的改进，主要是针对决定过渡矩阵的非局地混合潜势。目前的过渡矩阵表达方式使物理量在空间的分布不合理地过于均匀，造成了降水量的减少。
