In thermodynamics, the ratio of the work done by a heat engine to the total heat supplied by the heat source.
Industry:Weather
A Russian term applied to permanently unfrozen ground in regions of permafrost. This usually applies to a layer that lies above the permafrost but below the active layer, that is, when the permafrost table is deeper than the depth reached by winter freezing from the surface. Talik is also found within and beneath permafrost; when it occurs beneath the permafrost it is equivalent to subgelisol.
Industry:Weather
A term applied to the trade winds when they are shallow and exhibit a strong vertical shear. With this structure, the easterlies give way at about 1. 5 km to the upper westerlies (antitrades), which are sufficiently strong and deep to determine cloudiness and weather. The tropical easterlies occupy the poleward margin of the Tropics in summer and can cover most of the tropical belt in winter. Compare equatorial easterlies.
Industry:Weather
In general, a climate that produces taiga vegetation; that is, one that is too cold for prolific tree growth but milder than the tundra climate and moist enough to promote appreciable vegetation. This climate type appears as a subdivision of Köppen's 1936 snow forest climate and Thornthwaite's 1931 microthermal climate.

In the Beaufort wind scale, wind with a speed from 56 to 63 knots (64 to 72 mph) or Beaufort Number 11 (Force 11).

Industry:Weather
The sum of the static pressure and the dynamic pressure when these concepts are applicable. Since this is the pressure at the stagnation point of a streamline, it is measured by an ideal Pitot tube directed exactly upstream. The total pressure satisfies the hydrostatic equation.
Industry:Weather
Waves generated by seismic activity. Tsunami are also popularly, but inaccurately, called tidal waves. When they reach shallow coastal regions, amplitudes may increase to several meters. The Pacific Ocean is particularly vulnerable to tsunami.
