Uncertainty in projections of streamflow changes due to climate change in California
[1] Understanding the uncertainty in the projected impacts of climate change on hydrology will help decision-makers interpret the confidence in different projected future hydrologic impacts. We focus on California, which is vulnerable to hydrologic impacts of climate change. We statistically bias correct and downscale temperature and precipitation projections from 10 GCMs participating in the C...
متن کاملAnalysis of Streamflow Changes under Climate Change Using Rainfall-Runoff Model in the Kor River Basin
Abstract In this study, the predicted monthly temperature and rainfall data from HadCM3 model (base period, ۱۹۷۲-۲۰۰۱) and next period (۲۰۱۱-۲۰۴۰) under A2emission scenario were used to investigate the impacts of climate change on runoff variations in the Kor river basin. HadCM3 model output was downscaled based on a temporal downscaling approach (Change Factor) and spatial downscaling appro...
متن کاملManaging Uncertainty in Climate Change Projections – Issues for Impact Assessment
Climate change projection is the term the IPCC Second Assessment Report (SAR) uses for model estimates of future climate. In that report, projections are presented in two forms: as single model scenarios and as projected ranges of uncertainty. In climate studies, scenarios are commonly regarded as being plausible, but have no further probability attached. Projected ranges of uncertainty can hav...
متن کاملCharacterizing the Uncertainty of Climate Change Projections Using Hierarchical Models
We present a suite of Bayesian hierarchical models that synthesize ensembles of climate model simulations, with the aim of reconciling different future projections of climate change, while characterizing their uncertainty in a rigorous fashion. Posterior distributions of future temperature and/or precipitation changes at regional scales are obtained, accounting for many peculiar data characteri...
متن کاملContribution of human and climate change impacts to changes in streamflow of Canada
Climate change exerts great influence on streamflow by changing precipitation, temperature, snowpack and potential evapotranspiration (PET), while human activities in a watershed can directly alter the runoff production and indirectly through affecting climatic variables. However, to separate contribution of anthropogenic and natural drivers to observed changes in streamflow is non-trivial. Her...
