A tornado's spin originates in wind shear, which is a difference in wind speed or direction at different altitudes. If this wind shear is strong enough air may start to roll in a phenomenon called horizontal vorticity. The updraft of a thunderstorm can then turn this vorticity vertical and take on the rotation to become a mesocyclone. Under the right conditions the mesocyclone can tighten and intensify to produce a smaller, stronger vortex: the tornado itself.
What else can I help you with?
A support in which a shaft rotates?
Bearing.
Does the crankshaft nut trun left or right to loosen?
AnswerLeft, counter-clockwise. Lefty loosey, righty tighty. --------------------------------------------------------------------------------It depends on which way the crank rotates. If it rotates clockwise the nut will be threaded on counterclockwise to prevent it from loosening. If the crank rotates counterclockwise then the nut will be threaded on clockwise.
What happens when a starter motor rotates at a high speed?
it burns
What is the shaft of which a wheel rotates?
Axle
What is cnc spindle?
the spindle of a CNC machine rotates the cutting tool.
What is an example of an object that rotates?
A wheel or the blades of a fan.
How many speed settings are on this Wall mount fan?
There are three speed settings for this fan and it rotates 90 degress.
Why does air come down when a fan rotates?
The blades of the fan have a small angle tilt, so it can push down air.
What is the unit rate for a fan that rotates 2000 times in 40 seconds?
50
What happens when the fan rotates backwards?
Air moves in opposite direction and if it's on a car-it will overheat
What is the rotation of the fan clutch nut on a 2005 Chevy trailblazer ls ext 4200 6 cylinder?
Lefty loosey to remove the fan clutch but the fan assembly rotates CCW when the engine is running.
What is a thin fan-shaped x ray beam that rotates around the patient?
CAT scan, or CT image
Why does fan collects dust on it even though it rotates?
Much dust is greasy and this aids its accumulation by impact. You'll find that the dust from a fan blade does not easily fall apart.
Where would you find the inclind plane on a fan?
The inclined plane on a fan is typically found on the blades. The angled shape of the blades creates an inclined plane that helps to move air more efficiently as the fan rotates.
Why fan rotates anticlockwise?
A fan motor has two parts namely rotor and stator. In a table fan blades are attached to rotor and its movement appears to be clockwise. In a ceiling fan, blades are attached to stator so blades appears to be moving anti clockwise.
When fan rotates we are unable to visualize individual blades why?
The human eye just can't focus on an object moving that fast.
How does a fan assisted air cooled engine operate?
the fan usually absorb about 1 hp for evry 15 to 20hp of output .it rotates by power produced in engine via belt
