Changes in the variability of global land precipitation
[1] In our warming climate there is a general expectation that the variability of precipitation (P) will increase at daily, monthly and inter-annual timescales. Here we analyse observations of monthly P (1940–2009) over the global land surface using a new theoretical framework that can distinguish changes in global P variance between space and time. We report a near-zero temporal trend in globa...
متن کاملPrecipitation and carbon-water coupling jointly control the interannual variability of global land gross primary production
Carbon uptake by terrestrial ecosystems is increasing along with the rising of atmospheric CO2 concentration. Embedded in this trend, recent studies suggested that the interannual variability (IAV) of global carbon fluxes may be dominated by semi-arid ecosystems, but the underlying mechanisms of this high variability in these specific regions are not well known. Here we derive an ensemble of gr...

متن کاملReduction of tropical land region precipitation variability 2 via transpiration
7 [1] Tropical rainforests are known to exhibit low intrasea8 sonal precipitation variability compared with oceanic areas 9 with similar mean precipitation in observations and models. 10 In the present study, the potential role of transpiration for 11 this difference in precipitation variability is investigated 12 using the National Center for Atmospheric Research 13 (NCAR) atmospheric general ...
متن کاملThe land use changes study and precipitation-runoff modelling using HEC-HMS, Case Study: Babolrood basin
Abstract Change in land use pattern influenced hydrological processes in basin and disrupt the normal balance of water flow. In the present research, hydrological parameters change of Babul Rod watershed basin has been that investigated concluded of land use changes in 1988 and 2009. To determine land use changes of Babul Rod watershed basin we has recruited TM satellite images 1988(1367) year ...
