英文摘要

One class of descriptions of landscape evaporation is based on the principle that actual evaporation E and atmospheric evaporative demand urn:x-wiley:00431397:media:wrcr25389:wrcr25389-math-0001 exhibit complementary behavior. A feature of some recent implementations of this approach is the need for the estimation of a free parameter, usually by calibration. In a different class of representations of landscape evaporation, several functional forms have been proposed in the past for the dependency of the mean annual evaporation precipitation ratio (E/P) on the mean annual aridity index urn:x-wiley:00431397:media:wrcr25389:wrcr25389-math-0002 - the Schreiber-Oldekop hypothesis, also known as the Budyko framework. While there is no general agreement in the literature on the optimal formulation of the “maximum possible evaporation” urn:x-wiley:00431397:media:wrcr25389:wrcr25389-math-0003, the functional forms of urn:x-wiley:00431397:media:wrcr25389:wrcr25389-math-0004 appear to be quite insensitive to its exact nature. This observation allows urn:x-wiley:00431397:media:wrcr25389:wrcr25389-math-0005 to be equated with the atmospheric evaporative demand urn:x-wiley:00431397:media:wrcr25389:wrcr25389-math-0006, and this immediately leads to a blending of the mean annual evaporation precipitation ratio (E/P) with the complementary evaporation principle, and the prediction of its unknown free parameter. As this free parameter is found to be relatively insensitive to time scale, the complementary functions become not only calibration-free at the mean annual time scale, but also applicable even at daily time scales. The results are shown to be applicable worldwide with experimental data from 524 catchment water balance set-ups and 156 high quality eddy covariance flux stations. The present approach offers a practical tool for the prediction of daily evaporation using only routine meteorological inputs including air temperature, specific humidity, wind speed, net radiation, and long-term average precipitation.
