Precipitation over Northern California under future climate conditions was obtained by dynamically downscaling IPCC CMIP5 future climate projection realizations. Six different future climate projection realizations from three general circulation models (GCMs: CCSM4, HadGEM2ES and MIROC5) based on two CMIP5 future climate scenarios (RCP4.5 and RCP8.5) were dynamically downscaled at 9 km resolution grids over eight study watersheds in Northern California for a period of 90 water years (2011 through 2100) by means of a regional climate model, the weather research and forecasting (WRF) model. Before investigating future climate change impacts based on the projections, model biases were corrected by comparing the dynamically downscaled precipitation based on the historical runs of the GCMs with the corresponding observations. The bias-corrected results were used to calculate basin-Average precipitation over the eight study watersheds. Here some results of basin-Average precipitation over the eight stud watershed are presented.

Impact of future climate change on watershed-scale precipitation was investigated over Northern California based on future climate projections by means of the dynamical downscaling approach. Thirteen different future climate projection realizations from two general circulation models (GCMs: ECHAM5 and CCSM3) based on four emission scenarios (SRES A1B, A1FI, A2, and B1) were dynamically downscaled to 9-km resolution grids over eight watersheds in Northern California for a period of 90 water years (2010-2100)...

The impacts of climate change on watershed-scale precipitation through the 21st century were investigated over eight study watersheds in Northern California based on dynamically downscaled CMIP5 future climate projections from three GCMs (CCSM4, HadGEM2-ES, and MIROC5) under the RCP4.5 and RCP8.5 future climate scenarios. After evaluating the modeling capability of the WRF model, the six future climate projections were dynamically downscaled by means of the WRF model over Northern California at 9 km grid re...

A point-location-based analysis of future climate change impacts on snow accumulation and melting processes was conducted over three study watersheds in Northern California during a 90-year future period by means of snow regime projections. The snow regime projections were obtained by means of a physically-based snow model with dynamically downscaled future climate projections. Then, atmospheric and snow-related variables, and their interrelations during the 21st century were investigated to reveal future c...

Impacts of climate change on the hydrologic processes under future climate change conditions were assessed over Muda and Dungunwatersheds of PeninsularMalaysia bymeans of a coupled regional climate and physically- based hydrology model utilizing an ensemble of future climate change projections. An ensemble of 15 different future climate realizations from coarse resolution global climate models' (GCMs) projections for the 21st century was dynamically downscaled to 6 km resolution over Peninsular Malaysia by ...

© 2022Mediterranean Basin is expected to be one of the regions most severely impacted by global climate change. However, the complex interactions of driving forces of climate in the region create a challenge for climate projections for the future. Findings from climate change studies support the inter-model and inter-regional variability of projections on climate change impacts. On the other hand, the studies on the evaluation of the simulation skills of high-resolution climate models for the region particu...
