2) Decreased relative humidity outside the leaf will increase the water potential gradient. Relative humidity: Drier surroundings give a steeper water potential gradient, and so increase the rate of transpiration. Wind: In still air, water lost due to transpiration can accumulate in the form of vapor close to the leaf surface.
Transpiration is a larger component of evapotranspiration (relative to evaporation) in vegetation-abundant areas. [14] As a result, denser vegetation, like forests, may increase evapotranspiration and reduce water yield. Two exceptions to this are cloud forests and rainforests. In cloud forests, trees collect the liquid water in fog or low ...
The biotic pump theory may be able to help us better understand the role forests have on the water cycle. The biotic pump is a theoretical concept that shows how forests create and control winds coming up from the ocean and in doing so bring water to the forests further inland.
With high wind speeds forecasted in the state, it'll feel much colder than the actual temperature. Here's what to know about wind chill and what the term means.
This animation shows the projected increase in potential evaporation in North America through the year 2100, relative to 1980, based on the combined results of multiple climate models. Potential evapotranspiration ( PET ) or potential evaporation ( PE ) is the amount of water that would be evaporated and transpired by a specific crop , soil or ...
However, when the wind is blowing, it will continuously blow that blanket of heat away from our bodies, leaving the skin exposed to the cold air. The faster the wind speed, the faster our body ...
Infrared image showing the importance of transpiration in keeping leaves cool. Plants can avoid overheating by minimising the amount of sunlight absorbed and by enhancing the cooling effects of wind and transpiration. Plants can reduce light absorption using reflective leaf hairs, scales, and waxes.
The wind chill also isn't a meteorologist's best guess at what the air outside feels like, because it's based on the actual measured temperature and wind speed.
