Re: Age of the Tide
My understanding is the tide acts like a wave travelling at approx 800 miles per hour and with no other influence follows directly under the moon. The other side of the world has another bulge caused by centrifugal force of the earth and moon orbiting each other (think hammer thrower). It would seem to me that with no other influencing factors the high tide follows directly under the moon although the sun with it's reduced gravitational influence will add a vector to the tide which should add slight lead or lags. Like the wake of a boat, however, as we get further away to the sides of directly under the moon, the tide would lag. Add in obstacles (land) and seabed geography, and things start to go funky - e.g. shallow waters will slow the tidal wave but increase it's height.
Anyway, that's just my basic understanding which could be entirely wrong!
