The core climate of the Canadian prairie region is defined as a semi-arid climate and is often based upon the Köppen climate classification system. [10]This type of classification encompasses five main climate types, with several categoric subtypes based on the precipitation pattern of the region. [11]
Tallgrass prairies receive over 30 inches of rainfall per year, whereas shortgrass prairies are much more arid, receiving only 12 inches or so, and mixed-grass prairies receive intermediate rainfall. [13] [14] Wet, mesic, and dry prairie ecosystems can also form more locally due to soil and terrain characteristics. Wet prairies may form in low ...
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.
The North American Environmental Atlas, produced by the Commission for Environmental Cooperation, a North American Free Trade Agreement (NAFTA) agency composed of the geographical agencies of the Mexican, American, and Canadian governments, uses the "Great Plains" as an ecoregion synonymous with predominant prairies and grasslands rather than ...

This was the worst drought for at least a hundred years in parts of the Canadian Prairies. Well below normal precipitation was reported in areas of Alberta and Saskatchewan for more than four consecutive years extending from autumn 1999 to spring 2004.
The tallgrass prairie ecosystem covered some 170 million acres (690,000 km 2) of North America. Besides agriculture, much of the shortgrass prairie became grazing land for domestic livestock . Short grasslands occur in semi-arid climates while tall grasslands are in areas of higher rainfall.
