Gaurav,
The error message:
fatal:Dimension sizes on right hand side of assignment do not match
dimension sizes of left hand side
is telling you that you have a statement where the dimensions of the array
being referenced on the left side of the equation don't match with the
dimensions of the right side.
I think line 51 in your code is this one:
slp2d = wrf_user_getvar(f,"slp",0)
My guess is that the error is occurring sometime after the first time
through the loop, and that "slp2d" is a different size than it was
previously.
NCL doesn't allow you to assign a new variable to an existing variable if
it's a different size or higher type.
You can easily fix this problem by using the reassignment operator, which
forces the reassignment to take place:
slp2d := wrf_user_getvar(f,"slp",0)
When you get error messages in NCL you don't understand, you might find an
explanation and solution on this page:
