And have there been any tornadoes in northern hemisphere which spiraled clockwise?

to answer your second question..yes northern hemisphere tornadoes can, although rare, rotate clockwise. Here is a link or two that address both questions.

Neither, the axis it rotates on is a north-south axis. However, the earth is spinning west to east!\n\nPS I wish people wouldn't say it rotates left or right - its meaningless and incorrect. If you look at the Earth with the North Pole at the top it appears to rotate to the right, but if you look at the Earth with the South Pole at the top it appears to rotate to the left. Use east and west! It rotates to the east!

It depends greatly on the shape of the tub or bowl and any currents in the water. There is a myth that in the northern hemisphere, water goes around the drain in a clockwise direction, because of the Coriolis Force (which affects how storms form due to the earth's rotation) - but generally our sinks and toilets and tubs aren't big enough to allow the Coriolis effect to exert as a factor.

It could. Anything could happen. A tornado hit NH this past week, so anything can happen!! :)\n\nPlus, haven't you seen "Day After Tomorrow"? That had a ton of tornados in LA! Blew the whole damn city away.

They are very rare, but I think as long as there is cold air clashing with warmer air (which can happen even in the winter), you can create conditions favorable to tornado developement. We had a severe snow storm in which we had thunder and lightning, the sky even turned slightly yellow....scary.

No, never. These are completely unrelated weather events. The spinning of a waterspout is caused by the close interaction of winds tavelling in different directions and/or at different speeds. It occurs on a very localised scale.\n\nThe spinning of a hurricane is caused by the coriolis forces actin on the air moving into a zone of low pressure. It occurs over a massive scale, sevaral hundred square miles commonly. \n\nThere is simply no way of converting one event into the other. It's like asking if a lightning bug can sometimnes becomes an atomic bomb because they both produce light. The differences are really that great.

I've never heard it been used in weather but some most-known related slang terms to tornadoes are: twister ,whirlwind ,wedge , funnel , gustnado, landspout, willy-willy , or rope.\n\nI hope thats enough.

one myth could be that tornadoes occur when a small asteroid hits the atmosphere with enough rotational velocity to twist the air\n\nor that they happen when god sneezes\n\nor that there is always at least one tornado on earth at any given time

There are no F6 tornadoes. F1 is the weakest and F5 is the most violent.\nF0-40-72 mph winds\nF1-73-112 mph winds\nF2-113-157 mph winds\nF3-158-206 mph winds\nF4-207-260 mph winds\nF5-261-318 mph winds\nNo tornadoes have been clocked at higher than 318 mph.\n\n69% of all tornadoes are F0 & 1\n29% of all tornadoes are F2 & 3\n2% of all tornadoes are F4 & 5

There is no "anti-clockwise" in the universe.  If you look at anything rotating from the other side, it goes the other way.

In meteorology, a cyclone is an area of low atmospheric pressure characterised by inward spiraling winds that spin clockwise in the northern hemisphere of the Earth, or counterclockwise in the southern hemisphere. It is a generic description covering a wide variety of different meteorological phenomena such as tropical cyclones, Extratropical cyclones and tornadoes, thus is rarely used by meteorologists without a qualifying term.\n\nThe terms hurricane and typhoon are regionally specific names for a strong tropical cyclone—a non-frontal, synoptic-scale, warm-core low-pressure system with cyclonic surface wind circulation (Holland 1993). Specifically, hurricanes generally refer to such storms in the Atlantic Basin and the Pacific Ocean east of the International Date Line. Typhoons refer to the storms in the north Pacific west of the International Date Line. The typhoon term has also been applied to tropical cyclones in the South Pacific or Indian Ocean, but this is not considered correct usage today\n\nare same

Neptunes axis spins counter clockwise. the rest also do the same except three of them; venus:clockwise, Uranus: rotates on side, Pluto: rotates down

a whirl pull usually creates in fast moving water and theyare ike little tornadoes under water that suck you down under. they create the same way a tornadoe does,but with water!!!!

As the heat of the sun--or anything else--causes air to rise, its radius of rotation changes; this change in radius would cause a change in the angular momentum, so to conserve the angular momentum of the particle, the rising air mass has to develop a small additional velocity (it turns out to be opposite the rotation of the earth) as rises.  Here, in the northern hemisphere, that air flow would go north and east.  Also, as the air moves north, the angular momentum changes--aggravating that easterly vector in the velocity.  Eventually, the air cools, and going down & back south causes more changes; oddly, and I can't recall the precise physics here, it still retains a major easterly vector.  Thus, because of the earth's spin, a particle of air that rises and falls in one of the large convection bands (living between the jet streams) will do a spiral--think a widely stretched spring, here.

Centers of a cyclone is a low-pressure region. Near the center of the cyclone the pressure gradient force, from high- to low-pressure regions, and the Coriolis force must be in an approximate balance (or else the cyclone would collapse in on itself under the pressure gradient). The wind flow around a large cyclone is counterclockwise in the northern hemisphere, and clockwise in the southern hemisphere, due to the Coriolis effect. Large anticyclonic storms are extremely rare on Earth, though Jupiter's Great Red Spot storm is anticyclonic.
