This #FullDiskFriday, we're providing a different view of the Northern Hemisphere to show the movement of the polar vortex from Jan. 18-22, 2025. This animation was created based on temperature data from the Advanced Technology Microwave Sounder (ATMS) instrument onboard NOAA's Joint Polar Satellite System satellites.

MULTI-VORTEX tornado! 🇨🇦🌪️😲 How many fingers do you see hit the ground? This is the longest-documented tornado in Canadian history - it stayed on the ground for 2.5 to 3 hours! A multi-vortex tornado is a powerful type of tornado that contains two or more finger-like vortexes rotating around the center. 🌪️ It produced winds over 210 km/h (130 mph). Very fortunate there was no fatalities. We chased this twister on July 27, 2015. #TornadoWatch #StormChasing #Tornado #Twisters #MultiVortex | R
