THORNTHWAITE'S POTENTIAL EVAPOTRANSPIRATION TERM
Canadian Geographies / Géographies canadiennes, 1965RÉSUMÉVu que la formule empirique de Thornthwaite pour évaluer l'évapotranspiration potentielle se manipule bien, elle semble avoir une base théorique latente. Ce concept se rapporte à un état d'équilibre dans le mouvement vertical de vapeur d'eau atmosphérique et, ainsi, le transport par mètre de hauteur est invariable dans les couches inférieures ...

AN EXPERIMENT TO MEASURE POTENTIAL EVAPOTRANSPIRATION
Canadian Journal of Research, 1948A method of obtaining daily values of the potential evaporating power of the atmosphere was used for the first time in Canada in 1947. The results verify Thornthwaite's formula for computing potential evapotranspiration in southern Ontario. The correlation between average runoff and computed water surplus for several watersheds in Ontario and Quebec ...

Evapotranspiration Potential of Green Infrastructure Vegetation
2021To better understand the evapotranspiration potential of urban vegetation, daily evapotranspiration (ET) of four species commonly found in green infrastructure in New York City and Philadelphia (A. incaranta, L. muscari, C. lurida, and E. purpurea) was measured using microlysimeters.

Scaling Potential Evapotranspiration with Greenhouse Warming
Journal of Climate, 2014Abstract Potential evapotranspiration (PET) is a supply-independent measure of the evaporative demand of a terrestrial climate—of basic importance in climatology, hydrology, and agriculture. Future increases in PET from greenhouse warming are often cited as key drivers of global trends toward drought and aridity.

Abstract Potential evapotranspiration (ETp) and reference crop evapotranspiration (ETo) differ in their developments, concepts, equations and application fields, however, many researchers have mixed the utilization of the two terms. Thus, it is necessary to clarify the terms to guide their proper usage.

Potential Evapotranspiration in Arid Regions
Journal of Applied Meteorology, 1964Abstract The concept of potential evapotranspiration, as applied to arid regions, is examined using an energy balance approach suggested by Budyko. Using data for Yuma, Ariz., it is shown that a 50 per cent increase in the relative humidity of the air above an irrigated field is accompanied by a 10 to 15 per cent decrease in potential ...

A Simple Apparatus for Measuring Potential Evapotranspiration
Nature, 1952THE combined process of evaporation from the soil and transpiration from plants is known as ‘evapotranspiration’. The amount of moisture so used varies from place to place and depends mainly on climate (especially temperature and precipitation) and the closeness of the vegetative cover.

Potential evapotranspiration at Simcoe, Southern Ontario
Archiv für Meteorologie, Geophysik und Bioklimatologie Serie B, 1968Several approaches to the evaluation of potential evapotranspiration (PE) are discussed from the point of view of the energy balance equation. Hourly and daily PE were evaluated for an irrigated ryegrass site near Simcoe in Southern Ontario during the summer of 1967 using the Bowen ratio and Penman solution of the energy balance equation, Thornthwaite ...

Abstract Using potential evapotranspiration (PET) to estimate crop actual evapotranspiration (AET) is a critical approach in hydrological models. However, which PET model performs best and can be used to predict crop AET over the entire growth season in arid regions still remains unclear. The six frequently-used PET models, i.e.
