使用的是WRF3.5.1版本,同化amsub资料,log文件中显示资料读取正常:

但是最后没有资料同化进去,没有参与迭代:
Diagnostics
Final cost function J = 0.00
Total number of obs. = 0
Final value of J = 0.00000
Final value of Jo = 0.00000
Final value of Jb = 0.00000
Final value of Jc = 0.00000
Final value of Je = 0.00000
Final value of Jp = 0.00000
Final value of Jl = 0.00000
Jb factor used = 1.00000
Je factor used = 1.00000
VarBC factor used FORTRAN STOP
= 1.00000
Total number of radiances = 0
Cost function for radiances = 0.00000
这个主要是什么原因造成的,我是按照同化卫星资料的步骤修改好了具体的namelist.input的,希望知道原因的同学指导一下,谢谢了。 |
