Sentences with phrase «hydrological cycle feedbacks»

We have ongoing work examining hydrological cycle feedbacks to changing climate forcings in simple climate system models, examing how solar variability affects climate variability and in applying the idea of maximum entropy production to model parameterization.

While there is at present no compelling reason to doubt the models» handling of water vapor feedback, it is not out of the question that some unanticipated behavior of the hydrological cycle could make the warming somewhat milder — or on the other hand, much, much worse.

Better understanding of feedbacks in the carbon and hydrological cycles are of great interest.

While there is at present no compelling reason to doubt the models» handling of water vapor feedback, it is not out of the question that some unanticipated behavior of the hydrological cycle could make the warming somewhat milder — or on the other hand, much, much worse.

I'm also interesting in the coupling between hydrological cycle, cloud feedbacks and circulation.

But it was always at a rate that could easily be accommodated by natural feedback processes if CO2 levels got too high — usually in the form of increased rock weathering through an acceleration of the hydrological cycle.

The natural acceleration of the the hydrological cycle that occurs when CO2 levels rise, increases rock weathering and is the key to the negative feedback that eventually pulls the atmospheric CO2 levels back down.

But this relationship is complicated by several feedback processes — most importantly the hydrological cycle — that are not well understood5, 6,7.

As yet, though the basics of the hydrological cycle are fairly well understood, we have very little comprehension of the complexity of the feedback loops.

As noted in the TAR (McAvaney et al., 2001), vegetation change during the mid-Holocene likely triggered changes in the hydrological cycle, explaining the wet conditions that prevailed in the Sahel region that were further enhanced by ocean feedbacks (Ganopolski et al., 1998; Braconnot et al., 1999), although soil moisture may have counteracted some of these feedbacks (Levis et al., 2004).

Impact on the hydrological cycle has the biggest impact cooling irrigated areas, but adding to water vapor feedback in others.

If a shift in the hydrological cycle were to lower the response in the global mean temperature, there may be a poisonous sting in such a negative feedback: changes in the precipitation patterns.

Better understanding of feedbacks in the carbon and hydrological cycles are of great interest.

We also have projects in the general area of non-linear geophysics such as examining climate feedbacks in the hydrological cycle and the effects of a variable sun on climate model simulations
