Is gravity greater at the Earths poles given an equal elevation at the Equator. I think we discussed we would weigh more at the pole than at the Equator for a given same elevation. Is this true?

*Hi ERRORIST, I'm not sure if this will help or is at least part of what you're looking for: http://antwrp.gsfc.nasa.gov/apod/ap030723.html]Click
It came to mind when I read your post. Additional and lengthier articles can be found via Google (sorry, I haven't the time currently to browse through those articles and, again, I'm not sure this is what you are looking for anyway).

Fascinating map it looks like Hurricanes form in areas of lower gravity if I read the map correctly.
Thanks for the link.I'll have to save that one for my favorites.

That's a gravity anomaly map and measures relatively small changes in gravity. They are mostly caused by plate tectonics; mountain chains and areas with oceanic trenches tend to have high gravity and ocean ridges, low gravity. Centrifugal force due to rotation I think makes a 200 pound man at the poles weigh 199.5 pounds at the equator. the effect is small but measurable. I think I read that 30 or more years ago in a popular science book.

WOW I am on to something here. If this is true then Hurricanes can be weakened by using the Earths rotational velocity as a vane in a pump."Earth The Giant Pump"
