Evapotranspiration (ET) refers to the combined processes which move water from the Earth's surface (open water and ice surfaces, bare soil and vegetation) into the atmosphere. [ 2 ] : 2908 It covers both water evaporation (movement of water to the air directly from soil, canopies , and water bodies) and transpiration (evaporation that occurs ...
Evapotranspiration is the combined processes moving water from the earth’s surface into the atmosphere. Transpiration is the movement of water through a plant and out of its leaves and other aerial parts into the atmosphere. This movement is driven by solar energy. [4]
Water stored in the soil remains there very briefly, because it is spread thinly across the Earth, and is readily lost by evaporation, transpiration, stream flow, or groundwater recharge. After evaporating, the residence time in the atmosphere is about 9 days before condensing and falling to the Earth as precipitation.
Factors like full sunshine in forested areas and deserts can affect the transfer of moisture in the air. Increased amounts of evaporation or transpiration will cause a reduction in atmospheric pressure as clouds form, which will subsequently cause moist air to be drawn to regions where evapotranspiration is at its highest. In a desert this will ...
These events will become more and more common as the Earth warms. [1]: Figure SPM.6 The effects of climate change on the water cycle are profound and have been described as an intensification or a strengthening of the water cycle (also called hydrologic cycle). [2]: 1079 This effect has been observed since at least 1980.
Thus far, greenhouse gases released by humans, such as CO2, have caused Earth's temperatures to rise nearly 2.5 degrees since the late 1800s, according to NASA. The ramifications of this warming ...
These changes in the natural landscape reduce evapotranspiration, and thus water vapor, in the atmosphere, limiting clouds and precipitation. It has been proposed, in the journal Atmospheric Chemistry and Physics , that evaporation rates from forested areas may exceed that of the oceans, creating zones of low pressure, which enhance the ...
