Sentences with phrase «evaporative demand»
"evaporative demand" refers to the amount of water that evaporates from surfaces due to heat and dryness. It describes how much moisture is being pulled into the air through evaporation. Full definition
The summer rainfall will have little effect on streamflow and the winter spring - rainfall will lead (with increases in evaporative demand) to a decrease in streamflow of > 10 %.

We also quantified the contribution of changes in the catchment efficiency parameter that oppose the effects of increasing evaporative demand in global warming scenarios.
The temperature - related reduction of cv was mainly due to a decrease in photosynthesis and only to lesser extent because of more autotrophic respiration and less stomatal conductance as a response to an increasing atmospheric evaporative demand.
Analyses showed that high - frequency irrigation resulted in higher root zone soil moisture content relative to low - frequency irrigation despite reduced evaporative demand during part of the growing season.
However, further analysis showed that the decline in NPP is in fact due to increased vapor pressure deficits causing stomatal closure and increased evaporative demand over temperate and tropical forests, with increasing nitrogen mineralization reducing the potential constraint from N feedbacks (Fig. 4).
Although precipitation deficits are a prerequisite for the moisture deficits that constitute «drought» (by any definition)(15), elevated temperatures can greatly amplify evaporative demand, thereby increasing overall drought intensity and impact (16, 17).
Donohue, R. J., McVicar, T. R. & Roderick, M. L. Assessing the ability of potential evaporation formulations to capture the dynamics in evaporative demand within a changing climate.
The switch in the sign of response in HYBRID4 is due to the removal of the beneficial effects of increasing CO2 on tree survival, leading to increased tree mortality with atmospheric evaporative demand.
Large trees are more vulnerable, in part, due to their physiology: it's harder for them to transport the water and nutrients they need to their leaves and evaporative demands are higher.
Evapotranspiration, Evaporative Demand, and Drought.
Dewes C., I. Rangwala, J. J. Barsugli, M. T. Hobbins and S. Kumar (March 2017): Drought risk assessment under climate change is sensitive to methodological choices for the estimation of evaporative demand.
