Dear GrADS Users

I am straggling to compute GPI ratio. I can generate four GPI terms ( RH,
VORT, MPI and VWS) separately and the whole GPI. In addition, I can divide
or subtract between terms of two data sets.

My problem is: when I display: (RH1-RH2)/(GPI1-GPI2)

It generates the following output which seems not alright.

What are possible problems for this?
