Probabilistic projections of 21st century climate change over Northern Eurasia
We present probabilistic projections of 21st century climate change over Northern Eurasia using the Massachusetts Institute of Technology (MIT) Integrated Global System Model (IGSM), an integrated assessment model that couples an Earth system model of intermediate complexity with a two-dimensional zonal-mean atmosphere to a human activity model. Regional climate change is obtained by two downsc...
متن کاملAssessment of Downscaling Methods in Predicting Climatic Parameters under Climate Change Status: A case study in Ardabil Synoptic Station
Climate change is an unprecedented change are taking place. Changes of meteorological parameters such as precipitation, maximum and minimum temperatures. Since weather forecasting is important for these parameters, in this study, the performance of Statistical Downscaling Model (SDSM and Lars-WG) were used to predict temperature and precipitation and mean of these changes for the periods 2046-2...
متن کاملStatistical downscaling of precipitation
Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract Global Circulation Models (GCMs) are a major tool used for future projections of climate change using different emission scenarios. However, for assessing the hydrological impacts of climate change at the watershed and the regional scale, ...
متن کاملDRAFT: Int. J. Climatology, 2007, in press (MS# IJOC-06-0225) Review of scenario selection and downscaling methods for the assessment of climate change impacts on hydrology in the United States Pacific Northwest
This paper reviews methods that have been used to evaluate global climate simulations and to downscale global climate scenarios for the assessment of climate impacts on hydrologic systems in the Pacific Northwest, USA. The approach described has been developed to facilitate integrated assessment research in support of regional resource management. Global climate model scenarios are evaluated an...
متن کاملEvaluating effect of downscaling methods; change-factor and LARS-WG on surface runoff (A case study of Azam-Harat River basin, Iran)
This study aims to evaluate effects of two downscaling methods; change-factor and statistical downscaling on therunoff of the Azam-Harat River located at Yazd province (with an arid climate) of Iran, under the A2 emission scenariofor the period of 2010-2039. For this purpose, CGCM3-AR4 model; a rainfall-runoff conceptual model, IHACRES; twodownscaling models, Change Factor and LARS-WG were appl...
