用WRF-3DVAR 同化的时候迭代出现这种问题
Inner iteration stopped after 200 iterations
Final: 200 iter, J= NaN, g= NaN
----------------------------------------------------------
Diagnostics
Final cost function J = NaN
Total number of obs. = 20662
Final value of J = NaN
Final value of Jo = NaN
Final value of Jb = NaN
Final value of Jc = 0.00000
Final value of Je = 0.00000
Final value of Jp = 0.00000
Final value of Jl = 0.00000
Final J / total num_obs = NaN
Jb factor used = 1.00000
Je factor used = 1.00000
VarBC factor used = 1.00000
