The equivalent longitudinal wind that aids the flight of an aircraft. See equivalent head wind.
Industry:Weather
A spectral measure of the total absorption of radiant energy by an absorption line or absorption band. It is the bandwidth of a hypothetical perfect absorber that would absorb the same amount of energy as the absorption line or absorption band.
Industry:Weather
The equivalent longitudinal wind that opposes the flight of an aircraft. See equivalent tail wind.
Industry:Weather
For an aerial route, that fictitious uniform wind everywhere parallel to the air route that would produce the same mean aircraft speed with respect to the earth's surface as the actual wind. This is the component of the wind parallel to the line of flight integrated along the entire route. See equivalent head wind, equivalent tail wind.
Industry:Weather
In meteorology, a surface along which a specified scalar quantity, that is, pressure or temperature, is constant.
Industry:Weather
Altitude that, in a standard atmosphere, corresponds to an air density equal to the mean atmospheric density for the season at an aerodrome.
Industry:Weather
The level in an equivalent barotropic model at which motions are equivalent to the vertical average of motions in the corresponding column.
Industry:Weather
In Mexico, during October to January, heavy, cold rains that last for several days.
Industry:Weather
1. Either of the two points of intersection of the sun's apparent annual path and the plane of the earth's equator, that is, a point of intersection of the ecliptic and the celestial equator. 2. Popularly, the time at which the sun passes directly above the equator; the “time of the equinox. ”
In northern latitudes the vernal equinox falls on or about 21 March, and the autumnal equinox on or about 22 September. These dates are reversed in the Southern Hemisphere. Compare solstice.
