Science / Tides and Currents / Level Of No Motion: A level (or layer) at which it is assumed that an isobaric surface coincides with a geopotential surface. A level (or layer) at which there is no horizontal pressure gradient force. MORE
Science / Tides and Currents / Geopotential Anomaly: The excess in geopotential difference over the standard geopotential difference [at a standard specific volume at 35 parts per thousand (?€°) and 0 degrees C] between isobaric surfaces. See geopote MORE
Science / Tides and Currents / Geopotential Topography: The topography of an equiscalar (usually isobaric) surface in terms of geopotential difference. As depicted on maps, isopleths are formed by the intersection of the isobaric surface with a series of g MORE
