Evaporation from the Mediterranean shelf waters off the Egyptian coast

Abstract

Evaporation from the Mediterranean shelf waters off the Egyptian coast was estimated during the period from August, 1983 to July, 1986, using different techniques. On the basis of the heat budget equations, evaporation was computed using R' and R respectively. Three different forms of the aerodynamic method were also used for computing the evaporation. The agreement between the calculated values of evaporation by means of Sverdrup's formula and the estimated ones from observation was good, and considerably better than the results obtained by the other formulae. The total evaporation during the year was about 155.6 cm from the observations and 151.5 cm based on Sverdrup formula. These values were slightly more than 145 cm, the mean evaporation for the Mediterranean
