Sentences with phrase «plant evapotranspiration»

The lower relative humidity and increased temperatures that would result from potential reductions in fog and low cloud cover could increase plant evapotranspiration rates, raise soil water deficits, and accelerate risks of forest fire.

Not exact matches

Reed beds present sludge dewatering by plant consumption, evapotranspiration, and drainage.

In the study, published in the Proceedings of the National Academy of Sciences (PNAS), the researchers found that these indirect effects explain, on average, 28 per cent of the total plant productivity response, and are almost equal to the size of direct effects on evapotranspiration (ET)-- the sum of evaporation and plant transpiration from the land to the atmosphere..

Evapotranspiration is another way plants can communicate with high - tech irrigation systems.

The study accounted for evapotranspiration, which is water released into the air through plant transpiration and soil evaporation, as well as precipitation, and surface water flowing into and out of the Central Valley.

Soil moisture sensors show, over time, how much water has gone into the ground, and how much has left, either from drainage or in the form of evapotranspiration from plants.

For Pokorny, the key is evapotranspiration, whereby plants continuously absorb and emit water in the form of vapor.

The apparent rise in evapotranspiration — the process by which water is transferred from the land to the atmosphere by evaporation from plants and soil — is increasing potential drought risk with rising temperature trends, especially during periodic drought cycles that have been linked with strong El Nino events.

Here it can be used by plants or evaporate directly, with water loss from both processes combined called evapotranspiration.

«Our observation that plants use roughly the same amount of water regardless of water availability suggests that a warmer or longer growing season may have a relatively small effect on evapotranspiration and thus could affect landscape water balances less than we previously thought,» Hamilton said.

Gentine's team is the first to isolate the response of vegetation from the global warming total complex response, which includes such variables for the water cycle as evapotranspiration (the water evaporated from the surface, both from plants and bare soil) soil moisture, and runoff.

Secondly, the plants also cool the air by evaporating water in a process known as evapotranspiration.

Continuously monitoring plant «water stress» is particularly critical in arid regions and traditionally has been done by measuring soil moisture content or developing evapotranspiration models that calculate the sum of ground surface evaporation and plant transpiration.

An important predictor of future ecosystem drought (defined as ecological drought in the Water chapter) susceptibility is the net balance of water gained through precipitation and water lost through evapotranspiration (the combined effect of water evaporation and the transpiration of water by plants).

As plants take in carbon dioxide for photosynthesis, they release water through evapotranspiration from their leaf pores, which helps them cool down in the hot sun, much as human sweat cools us down.

Rising temperatures should increase evapotranspiration, but plants may adapt by reducing water lost to transpiration.

(Evapotranspiration is the process by which water is transferred from soil and groundwater to the atmosphere through plant transpiration — loss of water through foliage — and soil evaporation.)

Early evidence suggests that globally, the rate of water loss from soil and plants (called «evapotranspiration») has declined, a finding reinforced by a global slowdown in plant growth.

evapotranspiration loss of water from the soil both by evaporation from the surface and transpiration from the plants growing thereon

Plants response to higher CO2 levels result in less water utilation for photosynthesis (esp C4) which results in large gains of leaf growth (more growth for same water)-- forcing evapotranspiration to increase.

Global warming affects evapotranspiration — the movement of water into the atmosphere from land and water surfaces and plants due to evaporation and transpiration — which is expected to lead to:

He modified it in 1948 by including a moisture index that relates the amount of moisture a plant needs to the amount available, known as the Potential Evapotranspiration (PE)(evapotranspiration is the combined moisture loss from the surface either directly, due to evaporation, or indirectly transpired through the plant tEvapotranspiration (PE)(evapotranspiration is the combined moisture loss from the surface either directly, due to evaporation, or indirectly transpired through the plant tevapotranspiration is the combined moisture loss from the surface either directly, due to evaporation, or indirectly transpired through the plant to the atmosphere).

In warm, dry regions, irrigation increases the amount of water available for plants to release into the air through a process called evapotranspiration.

These parameters regulate processes such as plant carbon uptake by photosynthesis and how precipitation is separated into evapotranspiration to the atmosphere and river runoff.

But H2O used to make sugar is very small compared to H2O lost by plants through evapotranspiration.

Another way of lowering your home's outdoor thermostat is a natural process called evapotranspiration, a combination of evaporation and transpiration from plants.
