Thus, where E exceeds P in the mean (such as over the subtropical oceans), it would do so even more, while areas where P exceeds E [e.g., the intertropical convergence zone (ITCZ) and high latitudes] would receive yet more precipitation excess
(Manabe and Wetherald 1980; Held and Soden 2006; Seager and Naik 2012; Bengtsson et al.
The loss is subtracted from the precipitation depth and the remaining depth is referred to as precipitation excess. In the study, soil conservation service curve number (SCS-CN) loss method was selected to estimate cumulative losses.
where [P.sub.e] and P are cumulative precipitation excess and rainfall depth at time t; S is potential maximum retention, a measure of the ability of a watershed to abstract and retain storm precipitation.
