A tornado is defined as a violently rotating column extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of two hundred and fifty miles per hour or more. Damage paths can be more than one mile wide and fifty miles long. In an average year‚ eight hundred tornadoes are reported nationwide‚ resulting in eighty deaths and over one thousand five hundred injuries. In the body of my essay‚ I will tell you about types of tornadoes

Creative Myth Since the time the Earth was orbiting around the Great Star‚ there has been chilling storms rumbling about around our world. These storms that send shivers up spines‚ but also calm the nerves are what human like to call thunderstorms. These thunderstorms consist of a wide variety of rain‚ a variety of colors of lightning‚ and loud‚ deafening roars of thunder. Some spit out life threatening tornados‚ hurricanes‚ and tsunamis. The question remains‚ where do these acts of nature come from

A hurricane is an intense tropical storm with powerful winds and heavy rain‚ also known as a cyclone. Hurricanes and tornadoes are both storm systems that can cause a lot of destruction. Hurricanes are much larger than tornadoes but tornadoes generate faster winds. They both need warm and cold air to become a hurricane or tornado‚ but are different in the way they form. Hurricanes and tornadoes both have a calm area at the center called an eye. The eye of a hurricane is the calmest. The winds around

known that tornados are the result of great instability in the atmosphere and often appear during severe thunderstorms (see appendix #1 for a scientific explanation on how it really starts). Strong updrafts present in severe thunderstorms result in a rotational momentum. Falling rain and/or snow probably drags air from aloft when it comes falling down. The combination of severe thunderstorms and sweltering heat are the breeding grounds for a tornados’ formation. The first sign of a tornado is

What is a tornado? A tornado is a violent rotating column of air extending from a thunderstorm to the ground. Tornados are particularly associated with severe thunderstorms because stronger storms make it easier for tornados to form. During a supercell storm‚ characterized by powerful updrafts‚ warm‚ less heavy air begins to rise and meets colder and heavier air above it. Wind shears make tornadoes easier to form. A wind shear is when a warmer air collides with a colder air. Faster air begins to

Hi my name is Emily Davis. In this essay I will be telling you about tornados. Most tornadoes are form from thunderstorms. You need warm‚ moist air from the Gulf of Mexico and cool‚ dry air from Canada. When these two air masses meet‚ they create instability in the atmosphere. Then‚ when it reaches the ground it is called a tornado. It is not fully understood about how exactly tornadoes form‚ grow and die. Tornado researchers are still trying to solve the tornado puzzle‚ but for every piece that

Sprites are incredibly massive‚ yet weak luminous flashes that appear high above cumulonimbus‚ a towering mass with a flat base at a fairly low altitude and often a flat top‚ clouds of an active thunderstorm. They also happen to be coincident with positive CG‚ or cloud-to-ground lightning strokes (Heavner‚ 2004). The discharge‚ or the presentation of a visible sprite‚ can last anywhere from 5ms to 300ms‚ but they are still incredibly hard to catch

agency for weather forecasting‚ flood control‚ astronomical observations‚ and time service. TROPICAL CYCLONE A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center‚ strong winds‚ and a spiral arrangement of thunderstorms that produce heavy rain. Tropical cyclones are typically between 100 and 4‚000 km (62 and 2‚485 mi) in diameter. A cyclone is turned into a hurricane when the wind speed reaches 120 kilometres per hour (75 mph).
