Alpine wetlands in the Tibetan Plateau (TP) play a crucial role in the regional hydrological cycle due to their strong influence on surface ecohydrological processes; therefore, understanding how TP wetlands respond to climate change is essential for projecting their future condition and potential vulnerability. We investigated the hydrological responses of a large TP wetland complex to recent ...

Climate involves a complex interplay of physical, chemical and biological processes of the atmosphere, ocean, sea-ice and land surface. It is now well understood that although detailed weather fluctuations can not be predicted beyond a certain time period, it is possible to predict several space-time averaged processes of atmosphere, land, ocean and sea-ice over a certain regions for a longer p...

Global patterns of biodiversity reflect both regional and local processes, but the relative importance of local ecological limits to species coexistence, as influenced by the physical environment, in contrast to regional processes including species production, dispersal, and extinction, is poorly understood. Failure to distinguish regional influences from local effects has been due, in part, to...

A methodology is described for probabilistic predictions of future climate. This is based on a set of ensemble simulations of equilibrium and time-dependent changes, carried out by perturbing poorly constrained parameters controlling key physical and biogeochemical processes in the HadCM3 coupled ocean-atmosphere global climate model. These (ongoing) experiments allow quantification of the effe...

The path and magnitude of future anthropogenic emissions of carbon dioxide will likely influence changes in climate that may impact the global forest sector. These responses in the global forest sector may have implications for international efforts to stabilize the atmospheric concentration of carbon dioxide. This study takes a step toward including the role of global forest sector in integrat...

Climate forcing in complex ecosystems can have profound implications for ecosystem sustainability and may thus challenge a precautionary ecosystem management. Climatic influences documented to affect various ecological functions on a global scale, may themselves be observed on quantitative or qualitative scales including regime shifts in complex marine ecosystems. This study investigates the po...

The e€ects of landscape changes on winter and spring snow-related processes, and on regional weather and climate are not thoroughly understood. In this study, a climate version of the Regional Atmospheric Modelling System (ClimRAMS) is used to investigate the e€ects of landscape change on seasonal snow depletion and its corresponding e€ects on atmospheric and hydrologic processes. Two simulatio...

extended abstract   introduction the most important indicator of climate in a region is vegetation community. climate can be different over large areas, because of changes in vegetation community. vegetation influences weather and climate in its surrounding areas mostly by way of evapotranspiration and albedo so they play a role in the earth’s energy balance. these effects on the earth’s energy...

Regional Climate Models RCMs are practical downscaling tools to yield regional climate information for assessing the impacts of climate variability and change The Paci c Northwest National Labora tory PNNL RCM based on the Penn State NCAR Mesoscale Model MM features a novel subgrid treatment of orographic precipitation for coupling climate hydrologic and ecologic processes at the watershed scal...
