Re: fun with tides

John, surely you are not serious. There ARE ocean tides at the equator! I
assume of course that you are talking about the Earth.

And one of your references talks about "tidal bulges." Now those there ain't.

I submit this from one of the NOAA sites Micheal listed
"High tides are produced in the ocean waters by the "heaping" action
resulting from the horizontal flow of water toward two regions of the
earth representing positions of maximum attraction of combined lunar and
solar gravitational forces. Low tides are created by a compensating
maximum withdrawal of water from regions around the earth midway between
these two humps. The alternation of high and low tides is caused by the
daily (or diurnal) rotation of the earth with respect to these two tidal
humps and two tidal depressions. The changing arrival time of any two
successive high or low tides at any one location is the result of
numerous factors later to be discussed."

Tidal humps sounds a lot like tidal bulges.
