[ncl-talk] Problems with plotting Cyclone Track

[Rick Brownrigg]

Hi,

The error message is telling you exactly the problem -- the dimensions of
the expression on the right hand side of an assignment must match the
dimensions of the variable on the left. More specifically, line 61 in your
script is:

    time(ifs) = wrf_user_list_times(f)

Time is a one dimension variable, declared as:

     time = new(ndate,string)

and wrf_user_list_time() returns an array of available times, so line 61 is
an attempt to assign an *element* of the time array to a 1D array of
indeterminate length.

Hope that helps...
Rick
