Evapotranspiration is defined as: "The combined processes through which water is transferred to the atmosphere from open water and ice surfaces, bare soil and vegetation that make up the Earth’s surface."

2019年9月8日 · Evapotranspiration is the sum of all processes by which water moves from the land surface to the atmosphere via evaporation and transpiration. Evapotranspiration includes water evaporation into the atmosphere from the soil surface, evaporation from the capillary fringe of the groundwater table, and evaporation from water bodies on land.

evapotranspiration, Loss of water from the soil both by evaporation from the soil surface and by transpiration from the leaves of the plants growing on it. Factors that affect the rate of evapotranspiration include the amount of solar radiation, atmospheric vapor pressure, temperature, wind, and soil moisture. Evapotranspiration accounts for ...

2018年9月14日 · An evapotranspiration (ET) map from the U.S. Geological Survey showing Sesasonal Cumulative ET Anomoly in the conterminous United States.

Lecture 10: Transpiration and Evapotranspiration. Key Questions. 1. What are stomata? 2. What controls the ascent of sap? 3. What controls transpiration? 4. What factors constitute evapotranspiration? 5. How does evapotranspiration control soil water storage? 6. How does logging affect streamflow?

2012年7月25日 · Actual rates of evapotranspiration only reach potential rates when water is not limiting (i.e., after a series of heavy rain events, soil at or above field capacity). However, when the amount of plant-available water in the soil decreases, the actual rate of ET quickly falls to a fraction of PET.

2023年8月22日 · Evapotranspiration (ET) — the distribution and partitioning of which is strongly mediated by vegetation — is central to the water, energy and carbon cycles. In this Review, we examine the...

Evapotranspiration is the the combination of evaporation from the ground surface and transpiration by vegetation. It includes both evaporation of free water from the surface...

5 天之前 · Projections of global terrestrial evapotranspiration (ET) are plagued by sizeable uncertainties. Here, we uncover bivariate emergent constraint relationships between projected global ET trends ...

2025年2月10日 · For flood-prone, developing nations where hydrological data is scarce, an innovative methodological approach is essential. This study aims to explore the potentiality of modelling daily evapotranspiration time series by checking causal relationship among the available climate variables in a flood-prone, data-deficient region like Samar in the Philippines. …
