A tornado that occurs within supercells that contain well-established midlevel mesocyclones.
Industry:Weather
A tract of low-lying land, especially in the Netherlands, that has been reclaimed from the sea or other body of water, and is protected by dikes.
Industry:Weather
A tower, generally constructed of steel, for displaying coastal storm-warning signals.
Industry:Weather
A time specified in the manual on the Global Observing System for making meteorological observations.
Industry:Weather
A time series having stable statistical properties in the following sense. Let ''x''(''t'') denote the value of the variable at time ''t''. Hold ''t'' fixed and imagine an indefinite series of repetitions of essentially the same generating process, giving rise to a population (ensemble) of values of ''x''(''t''). For a stationary time series, the ensemble probability distribution of ''x''(''t'') is independent of ''t''. When the probability distribution changes very gradually with ''t'', the time series is called quasi-stationary.
Industry:Weather
A tide having two high waters and two low waters each lunar day, with little or no diurnal inequality. This applies equally to solar tides and to atmospheric tides. Worldwide, semidiurnal tides are the most important because the global ocean is near to resonance at the period of semidiurnal gravitational forcing.
Industry:Weather
A thin film on the water surface, usually due to long-chain molecules with one hydrophilic end and one hydrophobic end. Such a film has a surface tension that varies with the surfactant concentration, and the resulting effect on the near-surface viscous boundary layer causes considerably enhanced damping of centimeter-scale waves.
Industry:Weather
A tidal current that flows continuously, with the direction of flow changing through all points of the compass during a tidal cycle; found away from coastal or shallow water flow restrictions, where reversing currents are more probable. Compare reversing current; See current ellipse.
Industry:Weather
A thermometer housing that prevents the direct airstream from affecting the thermometer. The air intake is reversed so that inertial forces prevent the heavier water and ice particles from following the reversed airstream. This allows the thermometer to operate free from moisture effects.
Industry:Weather
A thermometer mounted upon a frame connected to a handle at one end by means of a bearing or length of chain, so that the thermometer may be whirled by hand in order to provide the necessary ventilation.
