Evapotranspiration (E) is defined as actual evapotranspiration (Ea)—the actual rate at which water vapor is returned to the atmosphere from the ground and by plants and potential evapotranspiration (Ep)—the water vapor flux under ideal conditions of complete ground cover by plants, uniform plant height and leaf coverage, and an adequate water supply. What is EVAPOTRANSPIRATION (noun)? It is defined as a series of events in which interevent times are independently and identically distributed. Potential evapotranspiration (PET) is a representation of the environmental demand for evapotranspiration and represents the evapotranspiration rate of a short green crop (grass), completely shading the ground, of uniform height and with adequate water status in the soil profile. This demand incorporates the energy available for evaporation and the ability of the lower atmosphere to transport evaporated moisture away from the land surface. Evapotranspiration accounts for most of the water lost … A lysimeter (from Greek λύσις (loosening) and the suffix -meter) is a measuring device which can be used to measure the amount of actual evapotranspiration which is released by plants (usually crops or trees).

From professional translators, enterprises, web pages and freely available translation repositories. The most direct method of measuring evapotranspiration is with the eddy covariance technique in which fast fluctuations of vertical wind speed are correlated with fast fluctuations in atmospheric water vapor density. A. From the Cambridge English Corpus Since evapotranspiration losses are largely controlled by the meteorological conditions, seasonal evapotranspiration is nearly the same whether yields are high or low.
