Wind is solar energy, it's the product of the sun heating air. 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 |

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 |

A difference in terrain conditions directly affects how much friction is exerted.

After a million years, the air is moving at the same speed as the earth. All the inertia. solar is probably 99.9% of the wind cause. The differences in surface features will redirect the winds, but mostly solar. One of the hypothesis of the Woolly Mammoth die off, was a small meteor strike and a wobble of the earth. The resulting several hundred mile an hour winds with shade, caused a huge wind chill, flash freezing the mammoths. They are found popping out of glaciers with subtropical flowers in their teeth and undigested food in the gut. They are large enough that unless there was massive chilling the stomachs would have finished digesting the food. |

This mixing causes variations in air speed, and, consequently, "wind" is generated at the earth's surface Could you be thinking of frictional drag which slows down air close to the surface? Again, for friction to have an effect, the air must already be moving. The effect you're describing above accounts for only a tiny fraction of surface wind, which is what powers sailboats. In fact, without the spatial unequalness of the sun's heating, you wouldn't be able to feel any wind at all. You really should do just a tiny bit of research. If you did, you'd discover that the sun is the driving force that generates the pressure differentials which cause wind. If you want, I'll give you a few links to read: http://www.weatherquestions.com/What_causes_wind.htm http://www.theweatherprediction.com/habyhints/85/ A lot of good links to info he http://www.usatoday.com/weather/reso...cs/wworks0.htm and a pretty good explanation of the forces acting on moving air: http://www.physicalgeography.net/fundamentals/7n.html If you want more, there's plenty available both on the web and in the library. I suggest you try learning something for a change. Steve Here, stupid, from the link that YOU posted!!!!!: What causes wind? Wind is caused by air flowing from high pressure to low pressure. Since the Earth is rotating, however, the air does not flow directly from high to low pressure, but it is deflected to the right (in the Northern Hemisphere; to the left in the Southern Hemisphere), so that the wind flows around the high and low pressure areas. This effect of the wind "feeling the Earth turn underneath it" is important for very large and long-lived pressure systems. For small, short-lived systems (such as in the cold outflow of a thunderstorm) the wind will flow directly from high pressure to low pressure. The closer the high and low pressure areas are together, the stronger the "pressure gradient", and the stronger the winds. On weather maps, lines of constant pressure are drawn (as in the example, above) which are called "isobars". These isobars are usually labeled with their pressure value in millibars (mb). The closer these lines are together, the stronger the wind. The curvature of the isobars is also important to the wind speed. Given the same pressure gradient (isobar spacing), if they are curved anticyclonically (around the high pressure in the above example) the wind will be stronger. If the isobars are curved cyclonically (around the low pressure in the example above) the wind will be weaker. |

In other words, the rotation of the earth does affect the direction of the wind, but does not cause or create the wind from the git-go. Did you look at the web site I provided a link to? It said in plain words, the sun heats up the air unevenly and this causes wind. Period. I know that it is very difficult to admit that you're wrong, but you'll be a better person if you do. DSK |
