![]() ![]() Source: Illinois State Climatologist What Does Radar Confirmed Tornado Mean? Such maps typically indicate a tornado by a smaller area of red surrounded by a larger area of green. Brighter shades identify faster winds whereas darker shades show slower winds. Red indicates the winds moving away from the radar whereas green displays the winds moving toward the radar. Most sources that publish radar images or videos of tornado events use the two main colors, red and green. Modern technologies also allow people who are not weather experts to track tornadoes on radar maps with the help of specialized apps, such as RainViewer. As a result, scientists can research these dangerous events in real time, analyze their strength, direction, and speed, define the level of threat, and issue a short-term tornado warning. They can even define the wind speed and the size of objects in the atmosphere. Modern radars, such as the dual-pol radar, can deliver quality, colorful, and high-resolution images of tornadoes. Here’s what this tornado looked like on the radar: Exactly hook echoes indicate the high probability of tornado formation. Don Staggs, the radar technician, saw a “hook echo” and recorded it with a 35-mm camera. This historical event happened in Champaign, Illinois. On April 9, 1953, a radar “caught” the first tornado ever. Analysis of data from radiosondes became a primary method for tornado forecasting. ![]() The Weather Bureau and air force bases in Kansas, Nebraska, and Oklahoma provided radar coverage for this project. The first use of radars as weather prediction equipment took place in 1950 with the introduction of the Tornado Project. Already in 1944, advanced forecasts included tornadoes, but still, they could not predict the exact place or time of the storm. The word “tornado” remained banned until 1942, when the central United States suffered a great number of tornado strikes. Still, these warning signs were not enough to forecast a tornado in advance. However, after the Tri-State Tornado in 1925, Finley’s rules were brought back to life, helping the scientists to recognize the possibility of a tornado. Army Signal Corps banned the word “tornado” from official forecasts in order not to cause panic among the population. ![]() Unfortunately, Finley’s research encountered obstacles. Increasing wind speeds of the southeast, southwest, and northwest quadrants of the low.Presence of a well-defined low-pressure area.After 2 years, in 1884, he developed the 15 rules for tornado forecasting and published them in 1888. Army Signal Corps Sergeant, was responsible for that. The first attempts to predict the tornado, whirlwind, and cyclone events started as early as in 1882. How to Find Tornadoes on Radar? First Investigations At those times, there was no equipment that could predict a tornado coming, issue tornado warnings, and thus save human lives. Now guess what these catastrophic weather events have in common? That’s right – they happened quite a long time ago. The Glazier-Higgins-Woodward tornado of 1947 killed 181 people.Louis tornado happened in 1896 with 255 deaths. The Tupelo-Gainesville tornado occurred in 1936, taking away at least 203 lives.The exact number of deadly victims is unknown, but around 109 people were injured. The Great Natchez tornado took place in 1840.The Tri-State tornado was the deadliest one.Let’s take a look at the most damaging tornado events in US history: The most dangerous region concerning tornadoes is called Tornado Alley and includes several states, specifically, Texas, Oklahoma, Kansas, and Nebraska. According to the National Weather Service, about 80 people die because of tornadoes each year in the US. ![]() Most tornadoes occur in the United States, with the tornado season lasting from March to July. A tornado is an extremely dangerous natural phenomenon that causes destruction, injury, and often death. ![]()
