PPT-TIDES: Astronomical Forcing & Tidal Constituents

Parker MacCready January 2011 Reference Admiralty Manual of Tides Doodson amp Warburg 1941 His Majestys Stationery Office Orbital Force Balance Tides are forced by the sun and moon with similar physics The Moons forcing is about twice that of the sun. They follow a cycle that coincides with the 24 hour 50 minute lunar day the time it takes earth to make one complete rotation relative to the moon Along Americas Atlantic Coast two high and low tides occur daily with relatively little difference bet Ch. 5.4, 5.9-5.10).
