All other topics about postprocessing model data (GrADS and other software), about other numerical weather prediction software (including WRF-NMM and WRF-ARW discussion unrelated to UEMS/WRF EMS), and general meteorology talk go in this forum.
I want plot temperature at map and i want print maximum values for it. In other words plot temperature with colors for all grid and in the same map find it maximum value of temperature for one region (LONmin...LONmax, LATmin...LATmax) and print it on the same map.
