Sentences with phrase «land evapotranspiration»

University of Montana Professor John Kimball is among the team of researchers who published an article on Oct. 30 about their study on Nature magazine's website titled «Vegetation Greening and Climate Change Promote Multidecadal Rises of Global Land Evapotranspiration.»

The researchers produced a long - term global satellite record of land evapotranspiration using remote sensing satellite data.

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..

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.

But during the dry season, when the fields are fallow, evapotranspiration from agricultural land was an average of 60 percent lower than from native vegetation.

We estimate that removing 1 Pg C y − 1 via tropical afforestation would require at least 7 × 106 ha y − 1 of land, 0.09 Tg y − 1 of nitrogen, and 0.2 Tg y − 1 of phosphorous, and would increase evapotranspiration from those lands by almost 50 %.

To be sure, some of these effects (such as the impact of irrigation on surface water vapour, or land use changes on evapotranspiration) are not easily dealt with in terms of the tropospheric radiative forcing — a point that was well made in the National Academies report on radiative forcing (on which Dr. Pielke was an author).

«Influence of Land - Surface Evapotranspiration on the Earth's Climate.»

These methods have been significantly improved by fully coupling the hydrologic cycle among land, lake, and atmosphere.94, 95 Without accounting for that cycle of interactions, a study96 concluded that increases in precipitation would be negated by increases in winter evaporation from less ice cover and by increases in summer evaporation and evapotranspiration from warmer air temperatures, under a scenario of continued increases in global emissions (SRES A2 scenario).

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:

Land cover and land use change may have an impact on the surface albedo, evapotranspiration, sources and sinks of heat - trapping gases (greenhouse gases), or other properties of the climate system and may thus have a radiative forcing and / or other impacts on climate, locally or globaLand cover and land use change may have an impact on the surface albedo, evapotranspiration, sources and sinks of heat - trapping gases (greenhouse gases), or other properties of the climate system and may thus have a radiative forcing and / or other impacts on climate, locally or globaland use change may have an impact on the surface albedo, evapotranspiration, sources and sinks of heat - trapping gases (greenhouse gases), or other properties of the climate system and may thus have a radiative forcing and / or other impacts on climate, locally or globally.

Another contributing factor was evapotranspiration from the land surface, which is found to have acted as an important moisture source and was likely enhanced by antecedent rainfall that increased soil moisture over the northern Great Plains.

Compares LST, albedo, normalized differenced vegetation index (NDVI) and evapotranspiration (ET) between seven different land cover types

Gornitz et al. (1997) estimate that evapotranspiration of water from irrigated land leads to an increase in atmospheric water content and hence a fall in sea level of 0.14 to 0.15 mm / yr.

These schemes improve the representation of observed land hydrological processes such as runoff, evapotranspiration, and soil water storage (Niu and Yang 2007; Oleson et al. 2008).

Soil moisture is a key component in the land surface schemes in climate models, since it is closely related to evapotranspiration and thus to the apportioning of sensible and latent heat fluxes.

Vegetation cover changes caused by land use can alter regional and global climate through both biogeochemical (emissions of greenhouse gases and aerosols) and biogeophysical (albedo, evapotranspiration, and surface roughness) feedbacks with the atmosphere, with reverse effects following land abandonment, reforestation, and other vegetation recoveries (107).

Soil moisture controls the relationship between actual and potential evapotranspiration and hence is a key determinant of the recycling of moisture from the land surface to the atmosphere.
