does a tornado rotate from left to right ? if so y?

Answer 1

If you mean clockwise (anti-cyclonic) and counter-clockwise (cyclonic), they can rotate in either direction. For the northern hemisphere, around 90 percent of all funnel clouds and tornadoes rotate counter-clockwise. Coriolis effect does play a role in why such a large percentage will rotate counter-clockwise in the northern hemisphere, but it is not a direct role since the size of the circulation for a tornado is relatively small. The larger the circulation of a storm system, the stronger Coriolis force will play a part in how the system will circulate. In the case of tornadoes, the circulation of the thunderstorm and the immediate wind flow enviroment around the storm cell plays a more important factor. It will be too difficult to explain here the physics, so instead I can tell you in what situations you will likely find a clockwise spinning funnel cloud or tornado.

In the northern hemisphere, here are two examples of where you will likely see an anti-cyclonic or clockwise spinning tornado form.

1. A thunderstorm that splits into two thunderstorm cells. If the thunderstorm before the split was moving generally from west to east, the northern thunderstorm after the split will usually be the clockwise spinning cell. If this northern thunderstorm cell produces a funnel cloud or tornado, it will likely be also spinning clockwise.

2. If a bow echo forms on a line of thunderstorms, the southern end of the bow echo (bookend vorticy) will more likely be spinning clockwise. Any funnel cloud forming at this end of the bow will more likely spin clockwise (as the bow echo expands outward from the convective line).

It is a relatively rare event.

Answer 2

No! Tornadoes normally rotate counterclockwise in the northern hemisphere, but approximately 1 tornado in 100 rotates in an clockwise direction.

Answer 3

I must admit, I have no idea what "left to right" means when talking about rotation. The direction of rotation is typically given as CCW (counter clockwise) or CW (clockwise). I've also seen the term anticlockwise used for CCW.

Low pressure, like the cold fronts that breed tornadoes, sucks air inward towards that low pressure. As it is sucked inward, the Coriolis effect, which comes from the Earth's rotation, causes the resulting wind vector to shift from heading straight into the low pressure center to the right of that low pressure center...in that sense, the wind vector goes from left to right (more from center to right of center). As a result of that shift to the right in all the wind vectors, the wind travels CCW around the center of the low pressure.

The center of a tornado is about as low pressure as nature can give us. So the inward rushing air is shifted to the right of center resulting in a CCW rotation around the center of the tornado.

Answer 4

The Earth's rotation causes a force (the "Coriolis force") which influences the spin of large masses of air like tornadoes (and hurricanes, typhoons, cyclones and what not) and makes them turn clockwise in one hemisphere and counterclockwise in the other.

Answer 5

They usually, but not exclusively, rotate counterclockwise in the northern hemisphere (and clockwise in the southern) due to the corliolis effect. There are other more chaotic factors in their formation that cause some to rotate in the opposite direction instead. The corliolis effect does stack the deck in favor of one direction, though.

Answer 6

it is not moving to the right or to the left relative to trees or power poles in the distance, it may be moving towards you! Remember that although tornadoes usually move from southwest to northeast, they also move towards the east, the southeast, the north, and even northwest. .

Answer 7

it's called clockwise or counter clockwise...
it's left to right coming at you ...
right to left going away...
it's because of the earths rotation... and it's opposite south of the equator.

Answer 8

yes,and in australia they rotate right to left.

Answer 9

in case your automobile develop into walking on your keypad i'm taken aback there is a few thing left of it. after all i do not imagine that is the perfect communicate board for computer questions. they're going to probable allow you to understand to wish for it to remodel :)

Answer 10

yes
