Water vapour reaches the atmosphere primarily through evapotranspiration from a water source at the earth's surface. |
It categorises climate by balancing the rainfall, potential evapotranspiration and soil water-holding capacity. |
Water use or evapotranspiration is composed of two parts, transpiration from the plant and evaporation from the soil surface. |
To limit this phenomenon when sunshine, temperature or wind could cause the leaf to dry out, the tree reduces its evapotranspiration. |
With higher temperatures and increased evapotranspiration, drought would probably become more frequent. |
Deforestation also can have regional climatic effects because trees are a key link in the evapotranspiration cycle between soil and the atmosphere. |
