报告简介

The complementary relationship provides a framework for estimating land surfaceevaporation with basic meteorological observations by acknowledging the relationship between actuaevaporation, apparent potential evaporation and potential evaporation. As a key variable in thecomplementary relationship. potential evaporation estimates by conventional models have a longstanding problem in practical applications. That is, the meteorological forcings (i.e.. radiation anctemperature) employed in conventional potential evaporation models are observed under actuaconditions that are generally not saturated. Hence conventional potential evaporation models do notconform to the original definition of potential evaporation (i.e evaporation that would occur withan unlimited water supply). In this talk, I will first illustrate the proland provide a new approachror estimating potential evaporation that does follow the original potential evaporation definitionThen, I will show how the new potential evaporation estimate solves the internal inconsistencies irexisting complementary relationship models and leads to a new physical interpretation of thecomplementary relationship.
