Project Reports


The Northern Tornadoes Project (NTP) is a partnership between Western University and ImpactWx that aims to better detect tornado occurrence throughout Canada, improve severe and extreme weather prediction, mitigate against damage to people and property and investigate future implications due to climate change.

Western University also collaborates with Environment and Climate Change Canada, the University of Manitoba, and several international universities on this Project.
