Abstract
By means of evaporation data from mini evaporator of new Sihui meteorological station in 2009-2011, this paper selects 30 meteorological samples in order to build up a corresponding plural linear equation among sunlight, relative humidity, vapor pressure, wind speed and evaporation. According to back substitution of the known samples in Chaozhou meteorological station to empirical formula of evaporation,the estimated value of daily average evaporation in Chaozhou city is 1.2 times than the actual values. Therefore, this empirical formula with a relevant correction coefficient is compatibly applied to calculate the theoretical value of evaporative capacity in Lingnan in-land tropic of cancer and nearby regions along the coast. This theoretical value could be used as the base to judge whether there is a big difference in the evaporation caused by the rainfall, meanwhile it gives the reference data to the study on evaporative capacity of the earth surface.关键词
