how fast are tornado winds

Tornadoes usually occur during the spring and early summer.Tornadoes usually lasts only a few minutes, but they are very intense. Very often, the most devastating ones occur in Bangladesh. Tornadoes that occur over oceans are called waterspouts, they are usually weaker than tornadoes.The condition for a severe thunderstorm and for a tornado are basically same.

Best Answers Most tornadoes have wind speeds less than 110 miles per hour (180 km/h), are about 250 feet (80 m) across, and travel a few miles (several kilometers) before dissipating. The "high-swirl animation," shown here, which depicts a powerful tornado with 200-plus mph winds, the purple tubelike structures depict the movements of rapidly rotating vortices. How fast are a tornado’s winds? But hurricanes and tornadoes also differ in crucial ways, including their size and duration as well as how, when and where they form.Tornadoes are typically no more than a few hundred feet wide — although one twister that touched down in central Oklahoma in 2013 was more than Hurricanes can last for days or even weeks. Both produce powerful, swirling winds — and both can leave a path of death and destruction. But tornadoes can form at any time of year and in any area.Occasionally, tornadoes form over water to form twisters known as Hurricanes are rated on a five-point scale known as the Category 1 hurricanes produce sustained winds of 74 to 95 miles per hour — enough to break tree branches and cause minor damage to buildings and other structures. They can sweep away bridges and topple tall buildings.Hurricanes often spawn tornadoes as they make landfall. The damage from a tornado is determined by the speed of its winds. In the Southern Hemisphere, these storms rotate clockwise.Most hurricanes hit the U.S. in summer and early fall, when the Northern Hemisphere’s oceans are warmest. Tornadoes usually last no more than a few minutes.Hurricanes form over the Atlantic and Pacific oceans, near the equator and far from land. Based on estimates of the Enhanced Fujita Scale winds for an EF0 tornado, the weakest category, start at 65 mph (105 km/h). Tetsuya Theodore Fujita, a weather scientist, developed a scale known as the Fujita Tornado Intensity Scale to determine the damage based on wind speed (see table below).

The damage path of a tornado is usually less than 500 meters wide and it travels at less than 16 m/s. The vortex has relatively low pressure at the center and is shaped like a funnel.

)-Because of F 4/5 winds around the intense tornado vortex the F6 damage is not identifiable, so the highest tornado … Each year, the United States ranks number one in tornado incidence with Australia coming in second. Since the Fujita scale is based on the severity of damage resulting from high winds, an F6 or an F7 tornado is a theoretical construct.

Category 2 hurricanes (with sustained winds of 96 to 110 mph) can cause heavy damage to houses. I'm leaving e4 in the question since it is not an uncommon point of confusion. These storms can destroy houses and make entire areas uninhabitable for weeks or months.Tornadoes are rated according to a six-point scale known as the EF-0 tornadoes produce wind gusts of 65 mph to 85 mph — enough to break tree branches. Originally answered: “How fast of winds dose e4 tornado have?” The correct rating is EF4, not e4. “Their energy source is the warm ocean waters,” says Richard Pasch, a senior hurricane specialist at the National Hurricane Center in Miami.In the Northern Hemisphere, hurricanes spin counterclockwise and are typically driven roughly northwest by the trade winds. Category 3 hurricanes (with sustained winds of 111 to 129 mph) can uproot trees and down power lines and damage buildings. During a typical Atlantic hurricane season, which runs from Tornadoes, or twisters, form over land during so-called supercell thunderstorms, which produce powerful updrafts of wind that twist as they rise, says Bill Bunting, the chief of forecast operations at the National Weather Service’s Storm Prediction Center in Norman, Oklahoma.Bunting says the conditions that encourage the formation of tornadoes — including the collision of warm, humid air and cold, dry air — prevail between March and early June across what’s commonly referred to as Tornado Alley, an area that spans parts of Texas, Oklahoma, Kansas, Nebraska and South Dakota.
