Theory developed by Lord Kelvin in 1855 explaining the relatively large amplitude of the solar semidiurnal component of the atmospheric tides on the basis of the resonance of a hypothetical natural atmospheric oscillation of the same period. (From WMO International Meteorological Vocabulary. )
Industry:Weather
Third member of the alkane family, formula C<sub>3</sub>H<sub>8</sub>. Emissions of propane are usually associated with anthropogenic activity, and its presence in an air mass can be a good indicator of pollution.
Industry:Weather
Tide near the time of syzygy, when ranges between high water and low water are greatest. Compare neap tide, tropic tide, equatorial tide.
Industry:Weather
Tide of increased range when the moon is near perigee, its nearest approach to the earth in its elliptical orbit.
Industry:Weather
Tides generated by regular periodic meteorological forcing. These are principally at annual (seasonal changes in solar insolation), daily (solar-driven land and sea breeze), and twice-daily (solar-driven cycle in barometric pressure) periods.
Industry:Weather
Topographic waves generated over a shelf, typically by the wind acting in the presence of a coastal boundary. For an observer traveling with the wave, the coast is on the right in the Northern Hemisphere and on the left in the Southern Hemisphere. See'' also'' coastally trapped waves, Kelvin wave.
Industry:Weather
Trails of emissions, advected by the wind, that are laden with particulates and gaseous pollutants from a continuous source. Plumes are generally visible for at least a short distance downwind due to condensed water vapor, particulate loading, or visible gaseous compounds.
Industry:Weather
Transverse oscillation of a ship about its longitudinal axis. See pitch, yaw, ship motion.
Industry:Weather
Traveling wave in the stratosphere with a period of between four and five days and forced by diabatic heating in the troposphere. The diabatic forcing is manifested as cloud-brightness oscillations that are particularly prominent at 5°–10°N in the northern winter, indicating that they are oscillations in the intertropical convergence zone.
Industry:Weather
Turbulence that is not continuous in space, but is separated by regions of stability and laminar flow. Examples include the turbulence in a horizontal plane across the entrainment zone of the convective boundary layer, or a stable, nocturnal boundary layer with patches of turbulent flow caused by windbreaks scattered across the landscape.
