Extreme Events: Data Sources
The primary source of historic climate data on extreme events is Environment Canada.
Environment Canada hosts: Canada's National Climate Archive | Climate Normals & Averages 1971-2000. Climate normals are available for each weather station in Saskatchewan and include information on a variety of extremes. The attached example for North Battleford includes the following:
- Extreme maximum temperature in a month and year
- Extreme minimum temperature in a month and year
- Extreme daily rainfall and date
- Extreme daily snowfall and date
- Extreme snow depth at month end and date
- Maximum hourly wind speed, date and direction
- Maximum wind gust speed, date and direction
- Extreme humidex and date
- Extreme wind chill and date
Environment Canada provides annual summaries of the top 10 weather stories for Canada (since 1996) along with regional summaries (since 2000). (Visit archive). The summaries often reflect the extreme weather events that were experienced across the country in any one year.
Of particular interest for 2010 is the #6 story - Saskatchewan’s Summer of Storms. It highlights the thunderstorm, flooding, winds and tornadoes that were experienced across the southern portion of the province.
Atmospheric Hazards for the Prairies and Northern Regions
This regional website provides access to historic climate data and analysis, and information on how to prepare and adapt to atmospheric hazards or extreme events. The data is summarized by type of hazard as well as by selected sites from across the province. The site-specific information is useful to consider in adaptation planning for the specific community or surrounding area.
This national website includes an extensive section on hazardous weather. Part of the site provides information on extreme events by season (Table 1). The weather types are defined and links are provided to information on how to prepare for the event.
