Science / Tides and Currents / M2: Principal lunar semidiurnal constituent. This constituent represents the rotation of the Earth with respect to the Moon. Speed = 2T – 2s + 2h = 28.984,104,2° per solar hour.

M1, M2, M3

Business / Real Estate / M1, M2, M3: Three measurements of the United States money supply. M1, or the basic money supply, consists of cash in public hands, private checking accounts, credit union share accounts and demand deposits at thr MORE


Science / Tides and Currents / L2: Smaller lunar elliptic semi diurnal constituent. This constituent, with N2, modulates the amplitude and frequency of M2 for the effect of variation in the Moon's orbital speed due to its elliptical or MORE


Science / Tides and Currents / K2: Lunisolar semi diurnal constituent. This constituent modulates the amplitude and frequency of M2 and S2 for the declinational effect of the Moon and Sun, respectively. Speed = 2T + 2h = 30.082,137,3° MORE

M4, M6, M8

Science / Tides and Currents / M4, M6, M8: Shallow water over tides of the principal lunar constituent. See shallow water constituent. Speed of M4 = 2M2 = 4T – 4s + 4h = 57.968,208,4° per solar hour. Speed of M6 = 3M2 = 6T – 6s + 6h = 86. MORE

Lambda (82)

Science / Tides and Currents / Lambda (82): Smaller lunar evectional constituent. This constituent, with <2, :2, and (S2), modulates the amplitude and frequency of M2 for the effects of variation in solar attraction of the Moon. This attraction MORE


Science / Tides and Currents / Overtide: A harmonic tidal (or tidal current) constituent with a speed that is an exact multiple of the speed of one of the fundamental constituents derived from the development of the tide-producing force. The MORE
