then choose the stretching factors. It is ideal to find the minimum number of levels needed to work with the other values chosen. For e.g., if desiring more levels near the surface, use a smaller dzstretch_s.
新方法使用表面和上部拉伸因子(dz_stretch_s和dz_stretch_u)根据log p拉伸级别,直到最大厚度点(max_dz),并从厚度dzbot开始。 当厚度达到max_dz/2时,拉伸从dzstretch_s过渡到dzstretch_u。 dzbot=50 m且max_dz=1000 m时,作为dzstretch和p_top函数的最小级数 dzstretch = 1.1在最低1 km处有12个层,在...
使用dzstretch_s 和dzstretch_u时的层次数目的最小值 为了避免在对流层上部出现最大厚度,在达到恒定的d(logp)之前,拉伸层次需要延伸到对流层顶以上。这可以通过使用足够低的dzstretch_u值(但大于~1.02)来达到对流层顶,同时拉伸足够快来补偿递减率。 可以使用另外两个namelist来增加灵活性:dzbot是第一个在全层之间...

dzstretch的值影响着层的分布，如dzstretch = 1.1时，在最低1 km处有12个层，在10 km以下有34个层；dzstretch = 1.2时，在最低1 km处有9个层，在10 km以下有22个层；dzstretch = 1.3时，在最低1 km处有8个层，在10 km以下有18个层。使用dzstretch_s和dzstretch_u时，最小级别数...
