Science / Tides and Currents / OO1: Lunar diurnal, second-order, constituent. Speed = T + 2s + h = 16.139,101,7° per solar hour. MORE


Science / Tides and Currents / M1: Smaller lunar elliptic diurnal constituent. This constituent, with J1, modulates the amplitude of the declinational K1, for the effect of the Moon's elliptical orbit. A slightly slower constituent, de MORE


Science / Tides and Currents / K1: Lunisolar diurnal constituent. This constituent, with O1, expresses the effect of the Moon's declination. They account for diurnal inequality and, at extremes, diurnal tides. With P1, it expresses the MORE

Type Of Tide

Science / Tides and Currents / Type Of Tide: A classification based on characteristic forms of a tide curve. Qualitatively, when the two high waters and two low waters of each tidal day are approximately equal in height, the tide is said to be s MORE

Indian Spring Low Water

Science / Tides and Currents / Indian Spring Low Water: A datum originated by Professor G. H. Darwin when investigating the tides of India. It is an elevation depressed below mean sea level by an amount equal to the sum of the amplitudes of he harmonic con MORE

Age Of Diurnal Inequality

Science / Tides and Currents / Age Of Diurnal Inequality: The time interval between the maximum semimonthly north or south declination of the Moon and the maximum effect of declination upon range of tide or speed of the tidal current. The age may be computed MORE
