Hello, because I need to use WRF points for 3 months, the simulation results lead to too much precipitation, and I want to use nudging. I modified namelist.iput, and then reported the error as follows. Attached is my namelist.input and error log.

I don't think spectral nudging is a good option for your case. This is because your domain is pretty small (600 x 600km) and the resolution is high (delx=4km). I would suggest you run with analysis nudging, i.e., grid_fdda = 1.

Hope this is helpful. Please let me if you still have trouble with this case.
Thank you! But I don't quite understand why you should choose analytical nudging over spectral nudging. In addition, do you have any good suggestions for other parameter settings of nudging?
