Northern Tornadoes Project 🇨🇦
@westernuntp.bsky.social
Founded in 2017 at Western University with support from ImpactWX.com, NTP aims to detect and document all tornadoes in Canada and uncover Canada’s true tornado climatology. Now part of the Canadian Severe Storms Lab! See uwo.ca/ntp & cssl.ca.

These papers highlight complementary remote sensing approaches that can help improve spatial coverage and consistency of tornado intensity assessments. Grateful for @cssl.ca team who made these studies possible!

"Evaluating the Utility of NDVI as a Damage Indicator for Crops in the Enhanced Fujita Scale" tests how NDVI changes can be used to identify crop damage from tornadoes, describes limitations, and shows how NDVI can supplement ground surveys in agricultural areas (doi.org/10.1175/JAMC...).

"Synthetic Aperture Radar as a Tool for Tornado Classification in Forested Areas" demonstrates how SAR can reveal tornado damage signatures in strong tornadoes, offering a way to provide EF-scale ratings in heavily forested regions where optical imagery struggles (doi.org/10.1080/0703...).

Looks like only 10 tornadoes made it to the map somehow. Here is the same regional map showing all 11 tornadoes.

Yes, we are developing several different types of wind estimation tools that can be used in cases where the traditional EF scale can’t or is limited. Expect progress on that in the off-season.
