As a neap tide , partly technically inaccurate as neap tide is called those Tide , in the sun and moon seen from Earth at an angle of 90 ° to each other, so at Crescent . In this constellation, the tidal range of the sea is particularly low, as the gravitational influences of the sun and moon work in exactly the opposite direction. The difference between the high water level (“Nipphochwasser”, NpHW for short) and the previous low water (“Nipp low water”, NpNW for short) is particularly small and is referred to as the Nipptidenhub (NpTH for short).
The mean Nipptidenhub is z. B. in Cuxhaven about three quarters of the tide range at spring tide .
A nip tide occurs every 14 days.
In the German Bight , the tide of which is significantly influenced by the tide of the North Atlantic, there is a nipp delay of a few days, so that the nipp tide in Germany only occurs after the half moon.
