Although science is very advanced, there is not enough data to fully understand all the reasons behind tornado formation, but they are believed to occur when rotating thunderstorms form mesocyclones. Once the mesocyclone forms, temperature differentials cause air to wrap around it.Know More
Mesocyclones are vertical columns of air rotating and rising around an axis. In addition to tornadoes, they form severe thunderstorms and hail. Scientists believe they form due to strong changes in the direction or speed of the wind. These changes cause the lower regions of the atmosphere to begin spinning in a horizontal tube-like role, invisible to the human eye. The updraft of the thunderstorm causes the spinning air to transform from horizontal rotation to a vertical rotation.
Typically, tornadoes form as the intensity of the thunderstorm begins to decrease. The momentum and vacuum in the upper atmosphere siphon the air away from the ground. Small pockets of warm air create a back draft to draw the base of the storm to the ground. Tornadoes are generally less than one mile in diameter at the ground. The length of time the tornado remains on the ground depends on the amount of warm air remaining. Once the warm air is exhausted, the tornado dies.Learn more about Storms
Scattered thunderstorms cover a large area and are likely to include several storm rounds. Storm chaser Adam Lucio explains that "scattered" and "isolated" descriptors have no bearing on a thunderstorm's actual intensity. These descriptions refer to the coverage a thunderstorm has over a certain area.Full Answer >
Thunderstorms usually last for 30 minutes to an hour. They can happen in a singular fashion, in lines or in clusters. Some of the most dangerous thunderstorms happen when a single storm strikes in a location for a lengthy period of time.Full Answer >
Uganda is the country that has the most thunderstorms. The northern Lake Victoria of Kampala in Uganda experiences the maximum number of thunderstorms, at 242 days per year on average, compared to any other country in the world.Full Answer >
Though the chances of being struck by lightning while taking a shower, during a thunderstorm, are extremely small, lightning that hits a house can travel through metal pipes and shock anyone who touches a faucet. Approximately 10 to 20 people are harmed this way each year in the United States.Full Answer >
