嵌套格点位置问题

小莹子

菜鸟一枚，参考黄小仙的帖子，学习嵌套。中心经纬度点：116.39，39.92，e_we =  10,16,19,e_sn= 10, 16,19,

修改namelist.wps，在之后ncl util/plotgrids_new.ncl命令后显示   
(0)    Warning: Western edge of grid must be at least 5 grid points from mother domain!
(0)    Warning: Southern edge of grid must be at least 5 grid points from mother domain!
(0)    Warning: Eastern edge of grid must be at least 5 grid points from mother domain!
(0)    Warning: Northern edge of grid must be at least 5 grid points from mother domain!
(0)    Warning: Inner nest (domain = 2) is not fully contained in mother nest (domain = 1)!
(0)    For the current setup of mother domain = 1, you can only have a nest of size 10X10. Stopping Program!

我修改为10，16，22，还是不行，

就直接改成100，200，300.
    Warning: Western edge of grid must be at least 5 grid points from mother domain!
(0)    Warning: Southern edge of grid must be at least 5 grid points from mother domain!
(0)    Nest does not end on mother grid domain point. Try 199 or 202.
(0)    Nest does not end on mother grid domain point. Try 199 or 202.
(0)    Warning: Western edge of grid must be at least 5 grid points from mother domain!
(0)    Warning: Southern edge of grid must be at least 5 grid points from mother domain!
(0)    Nest does not end on mother grid domain point. Try 298 or 301.
(0)    Nest does not end on mother grid domain point. Try 298 or 301.


但可以出图，显示如上图所示，研究区域的中心显示错误。
希望得到大家的指导，深入对于格点数和嵌套的认识；我也去找找解决方法，多尝试尝试，两条路走。谢谢

子区域的we和sn貌似要等于3n+1

我下次注意下看看，初学者，谢谢指导。

加油，不要怕，多搜多看，指不定哪个就用上了
