The Canadian Prairies (usually referred to as simply the Prairies in Canada) is a region in Western Canada. It includes the Canadian portion of the Great Plains and the Prairie provinces , namely Alberta , Saskatchewan , and Manitoba . [ 2 ]
The formation of the Canadian Prairies started with the uplift of the Rocky Mountains near Alberta. The mountains created a rain shadow which resulted in lower precipitation rates downwind. [6] The parent material of most prairie soil was distributed during the last glacial advance that began about 110,000 years ago. The glaciers expanding ...
Although most regions of Canada have experienced drought, many of the southern regions of the Canadian Prairies and interior British Columbia are most susceptible. During the past two centuries, at least 40 droughts have occurred in western Canada with multi-year episodes being observed in the 1890s, 1910s, 1930s, 1960s, 1980s, and the early 2000s.
The Dust Bowl was a period of severe dust storms that greatly damaged the ecology and agriculture of the American and Canadian prairies during the 1930s. The phenomenon was caused by a combination of natural factors (severe drought ) and human-made factors: a failure to apply dryland farming methods to prevent wind erosion , most notably the ...
The theoretical maximum possible ground surface temperature has been estimated to be between 90 and 100 °C (194 and 212 °F) for dry, darkish soils of low thermal ...

A theoretical one-standard deviation shift in mean extreme rainfall intensity has been misreported as Environment Canada data, suggesting that storms occurring every 40 years are occurring every 6 years", [8] based on a standard, normal probability density function (see presentation 13:10). It has also been reported that 20 times more storms ...
The Northern Plains' climate is semi-arid and is prone to drought, annually receiving between 16 and 32 inches (410 and 810 mm) of precipitation, and average annual snowfall ranging between 15 and 30 inches (380 and 760 mm), with the greatest snowfall amounts occurring in the Texas panhandle and areas near the border with New Mexico.
