Mediterranean Water that leaves the Alboran Sea through the Strait of Gibraltar below a depth of 150 m, penetrating the North Atlantic Central Water in the Gulf of Cadiz. Initially, Gibraltar outflow water is advected by a turbulent contour current. It transforms into a neutrally balanced middepth flow at between 700 and 1200 m south of the Algarve coastline (south Portugal). Also called a Mediterranean Water tongue, its high salt content is caused by the arid climate of the European Mediterranean Sea.
Industry:Weather
Maximum depth of frozen ground during the winter. The term may refer to an individual winter, to an average over a number of years, or to the greatest depth since observations began. The frost line varies with the nature of soil and the protection afforded by vegetal ground cover and snow cover, as well as with the amount of seasonal cooling. Compare frost table, permafrost table.
Industry:Weather
Mathematical conditions on the velocity and stress at the material boundary of a fluid. The first condition is that the tangential component of velocity is continuous across a material boundary separating a fluid and another medium. The second condition is that the difference between the values of the stress on two surface elements parallel to the boundary and immediately on either side of it is a normal force due wholly to surface tension.
Industry:Weather
Marked difference in Doppler velocity values at azimuthally adjacent range gates indicating the presence of the radial component of vorticity. Vorticity may be due to the presence of a tornado-sized vortex (tornadic vortex signature) or it may simply be caused by wind shear across a discontinuity boundary.
Industry:Weather
Light sufficiently intense to cause physical discomfort or to reduce contrast below the level at which detail is discernible.
Industry:Weather
Local name for the strong sea breeze that brings significant lowering of summertime temperatures to the shores of southwestern Australia.
Industry:Weather
Large area, such as those in the Alps, carved out to depths of hundreds to thousands of meters by the erosive action of glaciers.
Industry:Weather
Irregular patches of bright material present in the solar photosphere forming a veined network in the vicinity of sunspots. These regions are a few hundred degrees Kelvin hotter than their surroundings. They have low contrast on the solar disk and are best observed near the solar limb. These features relate directly to plage or brightenings in the overlying chromosphere.
