While tornadoes touch down in the US an average of 1,300 times each year,the vast majority cause little to no fatalities. Understanding tornado severity and the Enhanced Fujita (EF) Scale is critical to assessing risk, as half of all tornado deaths are attributed to the rarest, most powerful EF4 and EF5 tornadoes. Learn how these ratings are determined and what thay mean for community safety.
FARGO — Around 1,300 tornadoes, on average, touch down somewhere in the United States per year. Around 60 deaths per year, on average, are caused by these 1,300 tornadoes, meaning there is fewer than one death for every 20 tornadoes. The most common EF0 (wind speed 65-85 mph) and EF1 (wind speed 86-110 mph) tornadoes rarely result in fatalities.
about half the tornado deaths, on average, are caused by the rarest EF4 (wind speeds 166-200 mph) and EF5 (wind speeds greater than 200 mph) tornadoes, which make up about 1% of all tornadoes. These tornadoes are capable of leveling structures, and even small towns. These most powerful tornadoes are the ones usually responsible for large numbers of fatalities at once.The 1957 north Fargo tornado was in this category. The EF rating is determined by surveying the type of damage caused by a tornado.A tornado is rated by its highest rating, even though it is not at that strength over its entire course.
John Wheeler is Chief Meteorologist for WDAY, a position he has had since May of 1985. Wheeler grew up in the south, in Louisiana and Alabama, and cites his family’s move to the Midwest as significant to developing his captivation with weather and climate. Wheeler lived in Wisconsin and Iowa as a teenager. He attended Iowa State university and achieved a B.S. degree in Meteorology in 1984. Wheeler worked about a year at WOI-TV in central Iowa before moving to Fargo and WDAY..
Tornadoes: Trends and Future Outlook
Table of Contents
Tornadoes, those awe-inspiring and destructive forces of nature, have always captured our attention. But what does the future hold for these swirling vortexes? Let’s delve into the potential trends and what they might mean for us.
Shifting Seasons and Locations
One of the most significant shifts we’re observing is the changing seasonality of tornadoes. While “Tornado Alley” in the central United States has long been the hotbed, we’re seeing an increase in tornado activity outside of the traditional peak seasons and locations. [[1]] This includes more tornadoes in the Southeast during the cooler months. This means that areas not typically prepared for tornadoes may need to adapt.
Real-life example: Recent data shows an uptick in tornado occurrences in states like Mississippi and alabama during the late fall and winter months, a trend that requires communities to reassess their preparedness strategies.
The Role of Climate Change
Climate change is a complex factor,and its direct impact on tornado frequency is still being studied. However,warmer temperatures and altered weather patterns are likely to influence the surroundings in which tornadoes form. This could lead to more frequent or more intense severe weather events, including tornadoes. The exact nature of this relationship is an active area of research.
Pro tip: Stay informed about climate change impacts in your region. Understanding these changes can definitely help you prepare for potential increases in severe weather.
Technological advancements in forecasting
Fortunately, advancements in technology are helping us better understand and predict tornadoes.Improved radar systems, sophisticated computer models, and enhanced satellite imagery are providing more accurate and timely warnings. This allows communities to take proactive measures to protect lives and property.
Case study: The development of high-resolution weather models has significantly improved the accuracy of tornado warnings, giving residents more time to seek shelter.
building Codes and Community Preparedness
As tornado patterns evolve, so must our building codes and community preparedness efforts. Strengthening building codes in vulnerable areas can help structures withstand stronger winds. Furthermore, educating the public about tornado safety, including the importance of having a safety plan and knowing where to take shelter, is crucial.
did you know? The Enhanced Fujita (EF) Scale, used to rate tornado intensity, is based on the damage caused by a tornado. this helps meteorologists assess the severity of the event.
FAQ
Q: Are tornadoes becoming more frequent?
A: While there’s no definitive answer, some studies suggest a shift in tornado patterns, with activity occurring outside of traditional “Tornado Alley.”
Q: How can I prepare for a tornado?
A: Have a safety plan, know where to take shelter, and stay informed about weather alerts.
Q: What is the EF scale?
A: The Enhanced Fujita Scale measures tornado intensity based on the damage caused.
Q: How are scientists studying tornadoes?
A: Scientists use advanced radar,computer models,and satellite imagery to study tornadoes.
Q: What is the role of climate change?
A: Climate change may influence the environment in which tornadoes form, possibly affecting their frequency and intensity.
The future of tornadoes is a topic of ongoing research and discussion. By staying informed, preparing for severe weather, and supporting advancements in forecasting and safety measures, we can all contribute to a safer future.
