Meteorological Tides

Science / Tides and Currents / Meteorological Tides: Tidal constituents having their origin in the daily or seasonal variations in weather conditions which may occur with some degree of periodicity. The principal meteorological constituents recognized i MORE

Equatorial Tides

Science / Tides and Currents / Equatorial Tides: Tides occurring semimonthly as a result of the Moon being over the Equator. At these times the tendency of the Moon to produce a diurnal inequality in the tide is at a minimum. MORE

Apogean Tides Or Tidal Currents

Science / Tides and Currents / Apogean Tides Or Tidal Currents: Tides of decreased range or currents of decreased speed occurring monthly as the result of the Moon being in apogee. The apogean range (An) of the tide is the average range occurring at the time of ap MORE

Tropic Tides

Science / Tides and Currents / Tropic Tides: Tides occurring semi-monthly when the effect of the Moon's maximum declination is greatest. At these times there is a tendency for an increase in the diurnal range. The tidal datums pertaining to the MORE

Spring Tides

Science / Marine Biology / Spring Tides: Fortnightly tides occurring when the vertical tidal range is maximal MORE
