1. 6. Statistical Downscaling of Precipitation from Large-scale Atmospheric Circulation : Comparison of Methods and Climate Regions

   Författare :Fredrik Wetterhall; Sven Halldin; Chong-Yu Xu; Lars-Christer Lundin; Deliang Chen; Hans von Storch; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Statistical; Downscaling; Precipitation; Large-scale circulation; PCA; TWS; Weather pattern; Regression; Weather generator; Hydrologi; Hydrology; Hydrologi;

   Sammanfattning : A global climate change may have large impacts on water resources on regional and global scales. General circulation models (GCMs) are the most used tools to evaluate climate-change scenarios on a global scale. They are, however, insufficiently describing the effects at the local scale. LÄS MER

3. 7. Global-Scale Modelling of the Land-Surface Water Balance : Development and Analysis of WASMOD-M

   Författare :Elin Widén-Nilsson; Sven Halldin; Chong-yu Xu; Lars-Christer Lundin; Jens Christian Refsgaard; Uppsala universitet; []
   Nyckelord :Hydrology; Global; Water balance; Runoff; Regionalisation; Model uncertainty; Multi-objective; Parameter; Evaluation criteria; Routing; Climate change; Hydrologi;

   Sammanfattning : Water is essential for all life on earth. Global population increase and climate change are projected to increase the water stress, which already today is very high in many areas of the world. The differences between the largest and smallest global runoff estimates exceed the highest continental runoff estimates. LÄS MER
