Bonsal Cuell Wheaton-2017-An assessment of historical and projected future hydro-climatic variability and extremes over southern watersheds in the Canadian Prairies

Since human activities and ecosystem health require adequate, reliable water supplies, hydro-climatic variability
and extremes pose serious threats to society and the environment. Previous studies have shown that the Canadian Prairies
normally experience considerable hydro-climatic variability, including periodic droughts and excessive moisture conditions,
which are mainly caused by mid-tropospheric circulations that disrupt expected precipitation and temperature patterns.
