摘要
在Chan和Cho作的基础上,用中α尺度位温扰动代替了原来的中β尺度位温扰动,并且增加了一个高度函数H(Z),模式还改变了相对湿度的分布,取了可供比较的两个试验,并运行了半地转湿大气锋生模式程序,积分一段时间后,绘出有关的物理量的等值线图,分析、比较了非绝热加热及初始位温扰动对物理量的影响。 试验结果表明:初始位温扰动为中α尺度比中β尺度更接近实际情况,对流层湿度分布不均匀,非绝热加热的作用比初始位温扰动的影响明显些。
Based on the work of Chan and Cho, a meso-β scale potential disturbance was replaced by a meso-α scale potential disturbance, and add an elevation function- H(z) , as:The distributions of relative humidity were changed two experiments which could be compared each other, and run the NSI semi-geostrophic humid atmosphere frontogenesis model produce. After run a period, some contour charts of some physical variables were drew , the effects of diabatic heating and initial potential temperature disturbance on were analyzed and compared physical variables.
