Evapotranspiration is the sum of evaporation and plant transpiration from the Earth's land and ocean surface to the atmosphere. Evaporation is the process by which water changes from a liquid to a gas or vapor. Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Evapotranspiration is a major component of the water cycle. It is influenced by factors such as temperature, humidity, wind speed, and solar radiation. High temperatures, low humidity, and strong winds can increase evapotranspiration rates. Conversely, high humidity and low temperatures tend to decrease it. Solar radiation provides the energy needed for evaporation and transpiration. Understanding evapotranspiration is crucial for various applications, including irrigation management, drought monitoring, and climate modeling. It helps in determining the amount of water needed for agriculture, predicting water availability in different regions, and assessing the impact of climate change on water resources.
