Explanation: Reuters is why it is so difficult to predict tornadoes

(Reuters) – A powerful tornado hit the US Midwest https://www.reuters.com/markets/commodities/devastated-kentucky-tornado-survivors-pick-through-debris-shelter-with-relatives-2021- 12- More than 12 to 100 people have been killed this weekend, attention has been drawn to existing warning systems and why storm movements that move so fast are so difficult to predict.

A tornado, a narrow, violently rotating column of air that extends from a storm to the ground, according to the National Oceanic and Atmospheric Administration. About 1,200 tornadoes occur each year in the United States.

Unlike hurricanes that can be seen in advance https://www.noaa.gov/explainers/hurricane-forecasting, a tornado clock lasts https://www.nssl.noaa.gov/education/svrwx101/tornadoes/forecasting . for four to four hours when suitable conditions for tornadoes develop in a given area.

Hurricanes are usually measured in hundreds of miles and can last for days or weeks. Scientists can usually predict the trajectory of a hurricane three or five days in advance. Tornadoes usually form within a few minutes, are usually about a hundred feet wide, and last a few minutes.

Tornado Clocks https://www.nssl.noaa.gov/education/svrwx101/tornadoes, unlike tornado warnings, are usually transmitted hours a few hours earlier by meteorologists across the United States who see and cover the weather 24/7. of one or more states. They point out that the weather conditions are good for creating a tornado, but that they do not necessarily cause a tornado.

Meteorologists at local National Weather Service offices warn of a tornado when observers or radars report a tornado https://www.weather.gov/safety/tornado-ww and pose a serious threat to life and property. on his way. The average time for tornado warnings is between eight and 18 minutes at https://weather.com/storms/tornado/news/2021-04-05-tornado-warning-nws-accuracy, according to Weather.com.

Many towns use public warning sirens at https://www.weather.gov/unr/Warning_Systems to warn of tornadoes, but rural areas and smaller towns do not. Most local radio and television stations broadcast alerts, many smartphone apps, and even FEMA-provided wireless emergency alerts from tornado and flood telephone towers.

Over the weekend the onset of the tornado outbreak was night thunderstorms, including a super cell storm that erupted in northeast Arkansas. That storm went from Arkansas and Missouri and to Tennessee and Kentucky.

This time it was more deadly because the tornadoes hit the night.

“It’s based on a visual confirmation of people entering a shelter. But at night, you know, you don’t have that,” said Jeff Masters, a meteorologist at Yale Climate Connections.

Masters added that the mile-wide size of the largest cell was another factor in the widespread destruction. “That means there’s no place to hide. It’s so big and so powerful that even though you’re in the shelter, you’re in danger of losing your life.”
