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 tropic tides are designated as tropic higher high water (tchhw), tropic lower high water (tclhw), tropic higher low water (tchlw), and tropic lower low water (tcllw).

Tropic Ranges

Science / Tides and Currents / Tropic Ranges: The great tropic range (Gc),or tropic range, is the difference in height between tropic higher high water and tropic lower low water. The small tropic range (Sc) is the difference in height between tr MORE

Tropic Inequalities

Science / Tides and Currents / Tropic Inequalities: Tropic high water inequality (HWQ) is the average difference between the two high waters of the day at the times of tropic tides. Tropic low water inequality (LWQ) is the average difference between th MORE

Tropic Intervals

Science / Tides and Currents / Tropic Intervals: Tropic higher high water interval (tchhwi) is the lunitidal interval pertaining to the higher high waters at the time of the tropic tides. Tropic lower low water interval (tcllwi) is the lunitidal int MORE
