Top insights and patterns from the historical tornado data, revealing the most important statistics about tornado activity in this region.
Detailed charts and visualizations revealing tornado patterns by intensity, seasonality, and impact. These analytics show historical trends and unique characteristics of tornado activity in this region.
Shows tornado frequency across different months of the year, highlighting seasonal patterns. This information helps identify peak tornado seasons and periods of heightened risk.
Identifies the counties most frequently affected by tornadoes in Alberta. This geographical breakdown helps pinpoint tornado hotspots and vulnerable areas.
Summary: Edmonton has experienced the highest number of tornadoes (11) in Alberta, accounting for 1.9% of all tornado events in this state. The top three most tornado-prone counties (Edmonton, Calgary, and Olds) account for 5% of all tornado activity.
Shows tornado frequency by year with both actual annual counts (bars) and a 5-year moving average (line) to reveal long-term trends. The moving average helps smooth out year-to-year variations, making it easier to identify patterns and changes over time.
Visualizes the financial impact of tornadoes over time with both actual yearly damage (bars) and a 5-year moving average (line) to reveal trends. Toggle between logarithmic and linear scales to view the data in different ways—log scale helps compare years with vastly different damage amounts, while linear scale shows absolute differences more clearly.
Shows the breakdown of tornadoes by intensity rating (EF/F scale). Vertical bars make it easy to compare the prevalence of different tornado strengths, with counts and percentages displayed above each bar.
Shows the average number of deaths and injuries per tornado for each intensity rating. This reveals the exponentially increasing danger as tornado strength increases—an EF3 tornado is many times more likely to cause casualties than an EF0 or EF1.Note: Combines historical F-scale (pre-2007) with modern EF-scale (2007+) data.
