In what conditions evaporative index (ET/P) can be greater than one. Because in most of the studies I have seen that ET/P is found below the water limit line. Please suggest.
In arid climates, the evapotranspiration (EV) is greater than the pricipitation this is due to the high temperature with low pricipitation through all the year. According to Global FAO database, in some regions of Somalia, the Potential Evapotranspiration (PET) exceeds the pricipitation, so whenever the evapotranspiration is greater the pricipitation the evaporative index curve (EV/P) is greater than 1.
