Sentences with phrase «irrigation in climate models»

Including irrigation in climate models brings the models another step closer to observations.

Not exact matches

Using a model of water flow into the lake, the researchers found that 60 % of this decline was caused by climate changes, such as change in precipitation and temperature, and that the remaining 40 % of the decline could be attributed to water resources development, such as diverting water for irrigation that would otherwise flow into the lake.

In addition, exclusion of human - related impacts such as irrigation, land use, and water diversion from most current climate models makes reliable projection of drought even less certain (Sheffield and Wood 2008).

In one sentence: Regions that depend primarily on irrigation from surface water will be more vulnerable to drought as the impacts of irrigation on water supply are most significant during times with low water flow, according to climate modeling research from Pacific Northwest National Laboratory.

Though irrigation is one of the major human practices that alters the Earth, it is not often accounted for in current climate models or climate change projections.

Research interests: Nexus of physical climate and human systems, including effects of explicit irrigation on non-local hydrology in climate models, effects of MJO amplification on flood extremes and tropical cyclogenesis.

Puma and his coauthor, Benjamin Cook, a climatologist at Goddard and Columbia's Lamont - Doherty Earth Observatory, are the first to look at the historic effects of mass watering on climate globally by analyzing temperature, precipitation and irrigation trends in a series of model simulations for the last century.

«The study points to the importance of including irrigation in regional and global climate models so that we can anticipate precipitation and temperature impacts, and better manage our land, water and food in stressed environments.»
