Tornadoes rarely occur in California because of the state's dry climate and low thunderstorm rate. According to the Tornado Project, California experienced approximately 300 tornadoes between 1950 and 2014. Californian tornadoes are generally small, weak and occur in California's Central Valley.Know More
According to TheWeatherPrediction.com, tornadoes spawn from thunderstorms. Thunderstorms form when warm, moist air that collides with a cooler, drier air mass. This happens frequently in the flat plains region of the central United States nicknamed "Tornado Alley." This region receives large amounts of warm, moist air from the Gulf of Mexico. The shear forces become stronger with a greater difference in temperature and humidity. The moist air California receives from the Pacific Ocean is much colder. Consequently, California experiences fewer thunderstorms, and therefore fewer tornadoes, compared to states such as Texas, Oklahoma and Kansas.
Tornadoes occasionally spawn in other parts of the United States. Like California, the states in the Great Lakes region are generally too dry and too cold to support tornado formation for most of the year. Southeastern states, such as Florida, are extremely humid and famous for frequent, heavy thunderstorms. Despite its heat and humidity, the area rarely experiences tornadoes because cold fronts rarely penetrate it.Learn more about Storms
The only significant similarity between tornadoes and hurricanes is that they both produce high-speed winds. Tornadoes form as the result of lingering strong vertical wind velocity and vertical temperature changes. Hurricanes form as the result of extended periods of weak vertical wind velocity and relatively low changes in atmospheric temperature.Full Answer >
Tornadoes are formed when warm air combines into storm clouds causing an updraft that mixes with a burst of colder air, which leads to rotation within the cloud. The down draft of cooler air causes the tornado to form, pulling more warm air from the ground. As the updraft strengthens, it mixes to create a spot of low pressure that pulls at the cloud's vortex and forms a funnel cloud.Full Answer >
Tornadoes injure and kill people, destroy property, take a heavy financial toll, disrupt communication and create severe anxiety. The number of deaths due to tornadoes varies significantly from year to year. For example, according to NOAA, in 2008, 126 people died, but in the following year, only 21 lives were lost. Tornadoes killed 553 people in 2011, but just 70 in 2012.Full Answer >
The dangers of tornadoes include flying debris that can destroy property and injure people, and violent winds that lift vehicles and rip off roofs. The primary danger of tornadoes is the flying debris, as this often destroys and injures more than what the winds pick up.Full Answer >
