A very small percentage of the wind on the planet is a "product of the sun heating air". In that case you'll now post what causes the rest??? Even the migration of the various entire systems from the west to the east is directly related to the sun. Anyway if you think otherwise I for one will read your explanation with interest. K Sure thing, ask and you shall receive. That above statement about migration of various entire systems is pure rubbish. Ever hear of the Coriolis Force? Guess not, huh? Anyway: Wind is the product of the movement of air. Air has a certain density and surrounds the earth for a layer of approximately 64km in altitude. Air exerts a downward pressure, which is referred to as atmospheric pressure. The pressure on the earth's surface is one atmosphere, or one "bar", at sea level (mean absolute sea level/masl). Air pressure is measured with a barometer. As the Earth rotates on its axis, gravity forces this relatively "heavy" air near the Earth's surface to spin round with it. However, the air higher up is less affected. The difference between the speed at which air moves close to the surface and the speed of air higher up forms vortexes or whirlpools. This mixing causes variations in air speed, and, consequently, "wind" is generated at the earth's surface Dear dear dear I shouldn't bother; but will of course:-) You've totally misunderstood the effect, the air doesn't get "dragged" along by the earths rotation it's part of the earth. The effect is when air is rotating vertically & horizontally at the same time, (it rises as a direct result of the sun's heat, then it cools & sinks in a cooler part of the earth, that direct route from say the equator to the poles appears to be deflected to the west because the earth rotates underneath. The atmosphere at exteme altitudes does migrate generally in a westerly direction at about 25 mph, but this is well above "surface weather" Please stop & think a few moments, if your understanding be right then most ground level weather systems would approach from the east?? yes??? If you want to argue you'll need to address this sooner or later so do it now. They don't; systems mostly approach from the west, why?? because the sun is heating the air always to the east making it rise, the colder air & entire systems at "ground level" move into that space. So the apparent direction of some winds (the trades mostly) appear to be deflected to the west (S become SE'ly & N becomes NE'ly), however the driving force for the wind itself is the sun heating air somewhere else. Sorry atl man, but at least you tried & that takes more guts than the liar Harry has. K Pure rubbish from you!!! You need to do a little research, as opposed to just running your ignorant mouth. The FACT remains, and is valid. Do some studying, then get back to me. |
