Starting to understand tornadoes

This week we’ll continue our look at severe thunderstorms, and specifically, the most deadly part: tornadoes. What are tornadoes and how do they form? A classic definition of a tornado is a violently rotating column of air that extends from a thunderstorm to the ground, which may or may not be visible as a funnel

Severe summer weather: Wind

With the return of summer-like heat last week we also saw the return of severe summer weather. Plenty of thunderstorms rumbled across the Prairies, bringing examples of all of the different types of severe weather we can expect to see. There was plenty of lightning, hail, some really strong winds, heavy rains and, last but


Monitoring thunderstorm movement

Storms can strengthen or weaken as they move. Use online and visual tools to track their movements


In the last issue we continued our look at thunderstorms and severe summer weather by examining the direction thunderstorms move. In this issue we’ll learn how to determine the strength of a thunderstorm. Pretty much any storm can produce severe weather.

A Technical Look At Lightning

Iknow I mentioned in my last severe weather article that I would be doing a detailed discussion about tornadoes sometime soon, but that sometime is not this week. Instead, I’ve decided to look at a particular aspect of thunderstorms that everyone has seen, can be deadly but rarely is, and is probably one of the


The Beauty And Power Of Thunderstorms

So far this year in Manitoba we haven’t had the warm temperatures needed for thunderstorms, never mind severe thunderstorms with tornadoes. Farther south there have been some killer tornadoes over the central and southern U.S. This week we’ll continue our look at tornadoes and severe summer weather, but instead of me rambling on and giving

Time To Think About Severe Weather

Last issue we began our look into severe weather and ended our discussion by introducing tornadoes. Over the last week there have been several outbreaks of severe weather over central and eastern parts of the U.S., with dozens of tornadoes reported and nearly 50 people killed. While this is still well to our south, it
