basskisser wrote: Here, stupid, from the link that YOU posted!!!!!: What causes wind? Wind is caused by air flowing from high pressure to low pressure. Correct. But you have conveniently ignored the basic cause of this pressure differential. 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. 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 Yes, YOU would be a better person. Anyone with reasoning skills would know that in the above statement, "wind flow" would mean????? Yes!!! WIND!!! This is from a science website: 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 |

All wind energy comes from solar heating. End of story. Here are a few links to support this claim (I picked easy links to start you out): http://infoweb.newsbank.com/elementa...bj031598_2.htm http://www.nationalgeographic.com/me...cts/amaz6.html http://www.escambia.k12.fl.us/schscn...indenergy.html http://www.wintecenergy.com/wind_power.html http://www.evsc.virginia.edu/~evscta...atmcomp_03.pdf Real scientists (you know, with the white lab coats and thick glasses) use real science to figure this stuff out. You can get some ideas about how the do this by looking at this link. http://www.spacer.com/news/quikscat-00a.html Wind blowing and the earths rotation in a nutshell: http://starfire.ne.uiuc.edu/ne201/co.../wind/why.html Mark Browne |

But, how do you account for winds when convection has stopped, ie: surface temps. stabilize. In short, it's the Jetstream. Now, what does the jet stream at high altitudes have to do with it, you ask? NOAA has excellent publications answering just those questions. The short answer it a lot. |

I think you're persuing a semantic quibble. The Earth's rotation does not transfer any energy into the atmosphere, ie it does not cause wind. Period. Not even the jet streams. Now, the Earth's rotation does very much influence the direction of wind and the formation of weather systems which go even further to influence wind. If you want to rant and rave the "the Earth's rotation causes wind" then have at it, but you're hanging off the edge of a cliff here. Maybe next we can debate what the meaning of "is" is.... go ahead without me. DSK |

The sun constantly blasts the earth with a kilowatt per square meter. Even If we can't see it on an overcast day, it's up there. This drives the massive convection circuit we call the jet streams. This drives a massive conveyer belt of warm from the warm equator to the cold poles. Convection never stops. There may be local (for us) pools of still air. This does not change the fact that a river of air flow by far overhead. The seeming random local weather can be thought of in much the same way as random bubbles of movement in a boiling pot - just a lot bigger and slower. The moving air is shaped by the Coriolis effect to form rotating pools of air. From our prospective the air seems relatively still. If you discount very small special cases (turbulence around a volcano) all air movement ultimately derives from solar heating. What's that - you ask about hurricanes? Solar heating of the water causing rising moist air! The Coriolis effect shapes this into cyclonic circulation. Mark Browne |

Mark Browne Mark, again, there are many, many NOAA publications available on the web, and in print, that explains weather patterns, winds, etc. much more clearly than I ever could here. Good reading. |
