An example of evapotranspiration is the process by which plants absorb water from the soil through their roots and release it into the atmosphere through their leaves. This process helps regulate the Earth's water cycle and influences weather patterns.
Solar radiation is the primary energy source for evapotranspiration. It drives the process of evaporation of water from surfaces and transpiration of water from plants into the atmosphere.
The total water vapor released from soil and ocean surfaces as well as from plant leaves is called evapotranspiration. This process involves the combined evaporation from soil and water bodies, and transpiration from plant leaves. Evapotranspiration plays a crucial role in the Earth's water cycle.
Evapotranspiration is the process by which water is transferred from the land to the atmosphere through evaporation from soil and plant surfaces, as well as transpiration from plants. It is a key component of the water cycle and plays a significant role in the movement of water through ecosystems.
Potential evapotranspiration is typically highest in hot, dry conditions with high solar radiation and low humidity. This is because the rate of evaporation from the soil and transpiration from plants increases under these conditions.
Evapotranspiration is primarily influenced by temperature, humidity, wind speed, and the availability of water in the soil. Higher temperatures increase the rate of evapotranspiration, while high humidity reduces it. Wind speed can enhance water loss through evapotranspiration. Additionally, the amount of water stored in the soil directly affects the rate of evapotranspiration.
Potential evapotranspiration can change due to factors such as temperature, humidity, wind speed, and solar radiation. An increase in any of these factors can lead to higher potential evapotranspiration rates, while a decrease in these factors can result in lower potential evapotranspiration. Changes in land use or vegetation cover can also impact potential evapotranspiration levels.

evapotranspiration
This process is called evapotranspiration.
The potential evapotranspiration concept was first introduced in the late 1940s and 50s by Penman and it is defined as " the amount of water transpired in a given time by a short green crop , completely shading the ground , of uniform height and with adequate water status in the soil profile ". Note that in the definition of potential evapotranspiration , the evapotranspiration rate is not related to a specific crop .

Evapotranspiration refers to the combined process of water surface evaporation, soil moisture evaporation, and plant transpiration. It is significant during a storm because the stormwater from evapotranspiration is a water budget component for wetlands, wet ponds, and other stormwater treatment practices.
Solar radiation is the primary energy source for evapotranspiration. It drives the process of evaporation of water from surfaces and transpiration of water from plants into the atmosphere.
