In Which Climate Type Does Potential Evapotranspiration Exceed Precipitation?

In Which Climate Type Does Potential Evapotranspiration Exceed Precipitation? A dryland is a place where annual potential evaporation exceeds annual precipitation. Where precipitation exceeds potential evapotranspiration the climate will be? MI=100*((P-Potential ET)/Potential ET), If precipitation (P) exceeds potential ET, the index is positive for humid or wet climates. If potential ET exceeds precipitation, the index
