Review on Regional Evaporation

A review of advances in regional evaporation research in recent years is presented,which includes four aspens:①measuring much more accurate point evaporatton,②obtaining surface meteorological and geographical information from remote sensing,③using CBL model for exchange of vapour between land surface and mixed layer,④improving land surface parameterization scheme in regional model for basin water and heat balance.These methods approach regional evaporation processes at different direction,which presents a more impressed understanding of regional evaporation.Because of the heterogeneity of land surface characteristics and complexity of evaporation processes,there are still some shortcomings and need improvement in these methods.
