How is climate change affecting tornado occurrences?
Our warming climate will most likely have an impact on tornado activity in Canada and other parts of the world. What exactly that impact might be and how quickly such changes might be observed is currently a topic of research.
The tornado climatology may be modified in time, space and/or intensity and the direction of such changes may be regional in nature. It is important to continue to build a high-quality national tornado data set in order to be able to detect such shifts.
