Winter thaw episodes, especially when accompanied by rain, can significantly deplete the winter snowpack, which is a critical water storage component in the mountainous headwater regions of the major river basins of western Canada. Here we identify the characteristic synoptic‐scale mid‐tropospheric atmospheric circulation regimes that tend to foster such extreme hydrologic events using self‐organizing map analysis of meteorolo...

Precipitation, temperature, and evaporative demand are the most dominant factors affecting water availability in a region. This study examines projected changes in these hydro‐climatic variables over western Canada under two greenhouse gas emissions scenarios using statistically downscaled, high resolution climate data generated by six Global Climate Models ( GCMs ) from the latest Coupled Model Intercomparison Project ( CMIP5...

Freshwater ice plays an important role in physical, biological, and chemical processes affecting cold‐region lakes. To examine the potential magnitude of climate‐change‐related impacts in ice‐cover characteristics, particularly its formation, duration, breakup, thickness, and structural composition over North America, this study employs a one‐dimensional, process‐based, lake simulation model, ‘MyLake’ (Multi‐year simulation mo...
