Several previous studies have reported declines in pan evaporation rate throughout the Northern Hemisphere of about 2-4 mm a -2 for various periods since the 1950s. A recent analysis of Australian pan evaporation reported a similar decline and raises the possibility that part of the phenomenon may b

## Abstract Theory relating changes in areaβaverage evaporation with changes in the evaporation from pans or open water is developed. Such changes can arise by Type (a) processes related to largeβscale changes in atmospheric concentrations and circulation that modify surface evaporation rates in th
## Abstract Pan evaporation, as a surrogate of potential evaporation, is reported to have decreased in different regions of the world since the 1950s. There is much literature to explain the decrease in pan evaporation using the soβcalled evaporation complimentary relationship hypothesis and it is
