Wisconsin Tornado Awareness Week takes place from April 8-12 and it is a crucial time to explore what makes tornadoes so powerful, their impacts, and how to stay safe when they strike. First things first, what is a tornado? A tornado is a violently rotating column of air that extends from a thunderstorm to the ground. These come from supercell storms that have strong updrafts (rising from warm air). They are often categorized by their funnel shape and incredible speed.
Names
Tornadoes are commonly referred to as “twisters” due to their twisting nature. The speed of tornado’s can be incredibly powerful, reaching up to 480 kilometers per hour! These speeds determine their classification according to the Fujita Scale, which ranges from F0 (weakest) to F5 (strongest). The force of tornado’s can uproot trees, lift cars, and tear roofs off houses with ease.
Size and Duration
Tornadoes vary greatly in size, with diameters ranging from a few meters to over a kilometer wide. Despite their compact appearance, their impact can be devastating. In terms of duration, tornadoes can be short-lived or persist for an hour or more. Despite their shortness, even a few seconds or more of a tornado’s fury can leave behind a widespread destruction.
Geographical Distribution
While tornadoes can occur across the globe, the majority of them are concentrated in the United States, particularly during the springtime. This region, often referred to as “Tornado Alley,” experiences a higher frequency of tornadoes due to the collision of warm, moist air from the Gulf of Mexico with cool, dry air from the Rockies.
Safety Measures
During tornado season, it’s crucial to be prepared and know what to do when a tornado warning is issued. Here are some safety tips:
- Have a Plan: Identify a safe location in your office or home, such as a basement or an interior room on the lowest floor, away from windows.
- Stay Informed: Keep a weather radio or smartphone handy to receive alerts and updates from local authorities.
- Practice Drills: Conduct tornado drills with your family members to ensure everyone knows what to do in the event of a tornado.
As we observe Wisconsin Tornado Awareness Week, let’s spread knowledge and awareness to protect ourselves, our loved ones, and our communities from the destructive force of tornados. Stay safe, stay informed, and be prepared.
