Transcript of Vortex Project group #7 Eljonai Jean-Baptiste

Eljonai Jean-Baptiste Vortex A birth of a Vortex
It take just the right ingredients to create the perfect storm. Understanding Tornadoes Physics in Tornadoes Random Facts During the months of April, May and June, when the jet stream pushes the cool polar font down south and the warm tropical font pushes it way to the north. Those to fonts collides and create cumulonimbus cloud (Super Cell). How does meteorologists know the strength and size of a vortex?
The Enhanced Fujita scale
was develop in 1971 by Tetsuya Theodore Fujita
storm chaser have deploy many complex instrument to get great readings
The reason why Mr. Fujita develop the scale to differentiates the intensity of tornadoes Archimedes Principle
Angular Momentum
Rotational Force
Coriolis Force 3 out of 4 tornadoes that happens in the world occurs in the U.S.
In 1967, Hurricane Beulah spawned 115 tornadoes.
The Tri-State tornadoes lasted for 3hrs and 30 mins Types of Tornadoes Tornadoes on other Planets Water spout
is a tornado travels on water

Dangerous Weather (Tornadoes)
Dangerous Weather ( A Chronology or weather) Dust Devil on Mars are 3 time the size that of on Earth, but since the wind pattern on Mars has little to no moister. They rarely cause any damage, because the dust storm is on strong enough. Archimedes Principle Angular Momentum Rotational Force an object that's immersed in liquid the force is equal to the weight of the displaced fluid, in other words its bouyancy Angular Momentum is a vector quantity that represents the rotational inertia and rotational velocity on an axis
another example of angular momentum is a figure skater the break down of how tornadoes work The negative buoyancy is how tornadoes gets from the wall cloud down to the ground because the Rear Flank Down draft. Formula: L= mvr
angular momentum= mass*velocity*radius is when an object is circling center, but its acceleration keeps the object from leaving the presence of the center. This keeps the object going until it stops. Tornadoes making history Tri-state tornadoes
Joplin Tornadoes

what these tornadoes have in common, they were one giant super cell that spawn more than 3 tornadoes. Tornadoes comes in different Size Waterspouts
v.s.
Land spouts Waterspouts needs the same ingredients as a regular tornado to form.
The humid air over the water form a lot of water vapor. Since wet air is lighter the water droplets get in the the atmosphere
Waterspout picks up fish and frogs and dumps over land sometimes. Within the Thunderstorm the warm air is push upward and twist around while the cold descend thus creating a vertical rotation in the storm cloud also called an Updraft. When the storm intensify the lower part of a storm or wall cloud a funnel begins to appear due to the downdraft. Eventually the Funnel touches down and become a vortex. Boom . Part 2 of Birth Doppler Radar detecting a possible tornadic activity (purple might a tornado) rope tornado mile wide "I can outrun a tornado, especially in a vehicle." NO you can not!
its very dangerous because tornadoes are very unpredictable. Air pressure the air pressure inside and outside the tornado are completing different. That why glass shatters because when a tornado passes it difference between it is great. Anatomy of Supercell Anvil
