What does friction do to a tornado?
Frictional force quickly weakens the farther you get from the ground. When a hurricane makes landfall, the winds near the ground slow down, while the upper-level winds keep their momentum. … The tornado’s strength is determined by the damage the tornado does, which is an estimate of the wind speed of its rotating winds.
What are the 3 types of motion a tornado has?
There are 3 horizontal motions that make up the winds within a tornado. These three motions are the tornadoes forward motion, The parent tornado circulation, and vortices within the parent tornado circulation. These three motions together make the wind speeds within a tornado extremely variable.
What is tornado in physics?
A tornado is a violent windstorm with a twisting, funnel shape cloud and is usually spawned by thunderstorms when cool air and warm air meet, forcing warm air to rise quickly. Damage from tornadoes are due to high speed winds and flying debris.
How do tornadoes form physics?
This rotation is caused by wind shear. When this rotating air is drawn into the updraft, it becomes tilted vertically. “The updraft lifts the rotating cylinder within the supercell. The rotating cylinder of air narrows, becoming stretched, and spins faster and faster forming a tornado,“ NOAA said.
What is a Category 1 tornado?
F1 Category Tornado
Moderate Tornado. Moderate damage: Peels surfaces off roofs; mobile homes pushed off foundations or overturned; outbuildings demolished; moving autos pushed off the roads; trees snapped or broken.
Do tornado have categories?
According to Enhanced Fujita Scale, the tornadoes in the United States and Canada can be rated in six categories: EF0, EF1, EF2, EF3, EF4 and EF5.
What is a tornado short answer?
A tornado is a violent rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of up to 300 mph. They can destroy large buildings, uproot trees and hurl vehicles hundreds of yards.
