Atmospheric tides, tidal movements of the atmosphere similar to those

of the ocean, and produced in the same manner by the attractive forces

of the sun and moon. — Inferior tide. See under Inferior, a. — To work

double tides. See under Work, v. t. — Tide day, the interval between

the occurrences of two consecutive maxima of the resultant wave at the

same place. Its length varies as the components of sun and moon waves

approach to, or recede from, one another. A retardation from this cause

is called the lagging of the tide, while the acceleration of the

recurrence of high water is termed the priming of the tide. See Lag of

the tide, under 2d Lag. — Tide dial, a dial to exhibit the state of the

tides at any time. — Tide gate. (a) An opening through which water may

flow freely when the tide sets in one direction, but which closes

automatically and prevents the water from flowing in the other

direction. (b) (Naut.) A place where the tide runs with great velocity,

as through a gate. — Tide gauge, a gauge for showing the height of the

tide; especially, a contrivance for registering the state of the tide

continuously at every instant of time. Brande & C. — Tide lock, a lock

situated between an inclosed basin, or a canal, and the tide water of a

harbor or river, when they are on different levels, so that craft can

pass either way at all times of the tide; — called also guard lock. —

Tide mill. (a) A mill operated by the tidal currents. (b) A mill for

clearing lands from tide water. — Tide rip, a body of water made rough

by the conflict of opposing tides or currents. — Tide table, a table

giving the time of the rise and fall of the tide at any place. - - Tide

water, water affected by the flow of the tide; hence, broadly, the

seaboard. — Tide wave, or Tidal wave, the swell of water as the tide

moves. That of the ocean is called primitive; that of bays or channels

derivative. Whewell. — Tide wheel, a water wheel so constructed as to

be moved by the ebb or flow of the tide.
