What you want is the "psim" UDF which computes the mean meridional
streamfunction. As of this writing it only exists in the form of a classic
UDF (only works with GrADS 1.9 and earlier). It is in the list of UDFs to be
included as an OpenGrADS extension for GrADS v2. For now, you can find
sources for the classic UDF by browsing the OpenGrADS UDF repository:
