A land breeze of Spain and Brazil, sometimes a northwest squall of foehn character.

A hygrometer that is artificially aspirated; in this way proper readings can be obtained within about three minutes. In the case of a naturally aspirated wet bulb, the correct wet-bulb temperature will be attained after approximately 15 minutes provided the water reservoir has about the same temperature as the air. If the water temperature differs substantially from that of the air, it may be necessary to wait up to 30 minutes.
Industry:Weather
A hydrometeorological message issued to provide appropriate information of hazardous and potentially life-threatening weather conditions. Examples of weather warnings include tornado warnings, severe thunderstorm warnings, flood and flash flood warnings, special marine warnings, fire weather red flag warnings, and winter storm warnings. See Also warning.
Industry:Weather
A halo in the form of an arc tangent to a circular halo. The most common of these are the upper and lower tangent arcs to the halo of 22°. They form separate arcs when the sun is low, but as the sun climbs they join to produce the circumscribed halo. These arcs are explained by refraction through the 60° prism sides of columnar crystals oriented with their long axes horizontal. See 46° lateral arcs.
Industry:Weather
A gravity wave in the free troposphere excited by boundary layer thermals overshooting into the capping inversion.
Industry:Weather
A graph used to determine the ground distance for air-route legs of a specified time interval. Time–distance relationships are often simplified by considering air, wind, and ground distances for flight legs of 1-h duration; thus, the hourly distance scale.
Industry:Weather
A graphical aid used in the reduction of data from a winds-aloft observation. The board is designed so that the projections of the path of a balloon as a function of azimuth may be graphed in a convenient manner. The separation of the points that correspond to the horizontal wind is read from a special measuring scale converting distance to speed.
Industry:Weather
A graph showing the variation of a meteorological event with height.
