STD 2005/06/07
Code:

Concept definition:
A <
TIDE
> of decreased range (or tidal <
WATER_CURRENT
>s of decreased <<
WATER_CURRENT_SPEED
>>) occurring semi-monthly as the result of the <
MOON
> being in quadrature; neap tide [
TCG
, "neap tides or tidal currents"]. The neap range of the <
TIDE
> is the mean range occurring at the time of neap <
TIDE
>s and is most conveniently computed from the harmonic constants. It is smaller than the mean range where the type of <
TIDE
> is either semi-diurnal or mixed and is of no practical significance where the type of <
TIDE
> is predominantly diurnal.
