A deep trough at 31. 3°S, 39. 4°W in the Rio Grande Rise, South Atlantic Ocean, with a depth of 4646 m and a width of approximately 18 km. The Vema Channel acts as a conduit for Weddell Sea Bottom Water and Antarctic Bottom Water (potential temperature below 2°C) between the Argentine and the Brazil Basins, with a mean transport at 4 Sv (4 × 10<sup>6</sup> m<sup>3</sup>s<sup>−1</sup>). Named after the research vessel “Vema” of the former Lamont–Doherty Geological Observatory, Palisades, New York (now Lamont–Doherty Earth Observatory).
Industry:Weather
A daily sea breeze of about 7 m s<sup>−1</sup> (15 mph) from the southwest in summer on the Mediterranean coast east of the Rhône delta, extending some 32 km (20 miles) inland.
Industry:Weather
A curve tangent at every point of a field to the vorticity vector at that point.
Industry:Weather
A current of the North Atlantic subpolar gyre flowing northward along the west coast of Greenland. It is fed from the East Greenland Current and from the cyclonic circulation of the Labrador Sea and achieves a transport of over 30 Sv (30 × 10<sup>6</sup> m<sup>3</sup> s<sup>−1</sup>). Some of its water turns westward at 64°N to join the Labrador Current; the remainder continues northward as a relatively warm current through Davis Strait and into Baffin Bay, where it can be seen as a temperature maximum of greater than 1°C at a depth of 500 m. This water eventually turns westward as well to feed the Baffin Current and through it the Labrador Current.
Industry:Weather
A crack between the moving sea ice and the unmoving ice foot. It may widen to form a shore lead.
Industry:Weather
A coordinate system in atmospheric dynamics in which θ (potential temperature) is used as the vertical coordinate.
Industry:Weather
A current flowing underneath another current at a different speed or in the opposite direction.
Industry:Weather
A continental air mass that develops over or near tropical regions, typically equatorward of 30° latitude.
Industry:Weather
A convenient and frequently used term for the cloud mass of a thunderstorm, that is, a cumulonimbus.
Industry:Weather
A complete set of eigenfunctions of a vertical eigenvalue problem derived from the linearized governing equations of fluid motions of given mean stratification. These modes are often referred to as natural or dynamic modes.
