An English name for the levante, more specifically applied to winds in the Straits of Gibraltar and on the east coast of Spain. It blows from east or northeast with high pressure over central Europe and a depression over the southwest Mediterranean. It is most frequent and strongest from October to December and February to May, and persists for two or three days.

An easterly wind (from Lombardy) that predominates along the French–Italian frontier. It comes from the High Alps. In winter it is violent and forms snowdrifts in the mountain valleys. In the plains it is gentle and very dry. It is associated with an anticyclone over France and central Europe, or with high pressure to the southeast of Europe and low pressure to the northwest along with falling pressure over western France.

An atmospheric tide due to the gravitational attraction of the moon. The only detectable components are the 12-lunar-hour or semidiurnal, as in the oceanic tides, and two others of very nearly the same period. The amplitude of this atmospheric tide is so small, about 0. 06 mb in the Tropics and 0. 02 mb in middle latitudes, that it is detected only by careful statistical analysis of a long record. See tide.

An aquifer that is overlaid or underlaid by a semipermeable geologic layer.

An antenna consisting of a conducting coil of any convenient cross section, generally circular, that emits and receives radio energy. The principal lobe of the radiation pattern is wide and is in the direction perpendicular to the plane of the loop. Its primary application in radio meteorology is to the detection of such low frequency radio waves as are employed in sferics and in certain radio direction-finding equipment.

Aerodrome forecast indicating the weather at a specific aerodrome, intended to meet the requirements of local users and aircraft within one hour's flying time of the aerodrome.

Absorption due to one or more discrete absorption lines. Compare band absorption, continuum absorption.
Industry:Weather
A wind, similar in origin to the sea breeze but generally weaker, blowing from the surface of a large lake onto the shores during the afternoon; it is caused by the difference in surface temperature of land and water as in the land and sea breeze system. In addition to area, the depth of the lake is an important factor; a shallow lake warms up rapidly and is less effective as the source of a lake breeze in summer than is a deep lake. Lake breezes are well developed around the Great Lakes of North America, where they temper the summer heat.
