[ncl-talk] Error- wrf model output wind plot

[swati shewale]

To get rid of the error

fatal:Number of dimensions in parameter (1) of (gsn_csm_vector) is (3), (2)
dimensions were expected

I think you need to keep atleast one (pressure) level fix (from dimension
'bottom_top | 55]' ) at which you want  to do plotting.
