Lowest daily minimum temperature observed during a given calendar month over a specified period of years.
Industry:Weather
Highest or lowest temperature observed over the whole period of observation.
Industry:Weather
In British climatology, a drought period of at least 15 days during which no measurable daily precipitation has fallen. In the United States similar criteria have been used to define a dry spell (which, in turn, has a different definition in Great Britain). Ordinarily, these criteria are applied regardless of the season of the year.
Industry:Weather
(Or absolute reference frame. ) The inertial coordinate system that has its origin on the axis of the earth and is fixed with respect to the stars. Thus, any mechanical quantities in meteorology defined with respect to this frame take into account the rotation of the earth. See Coriolis force, absolute vorticity.
Industry:Weather
A combined electrical substitution and cavity radiometer where the electrical substitution inequivalence, efficiency of the cavity, the area of the entrance aperture, radiative and conductive losses, and other energy exchanges are accounted for such that the electrically substituted heating can be absolutely equated to the radiant heating of the detector. Most currently existing absolute cavity radiometers are designed for the measurement of direct solar irradiance. The World Radiation Reference (WRR) scale for solar irradiance observations used in many meteorological and climatological applications is defined by a group of well-characterized absolute cavity radiometers maintained by the World Radiation Center (WRC) in Davos, Switzerland.
Industry:Weather
The difference between the highest and lowest temperature observed at a location.
Industry:Weather
Different from normal in whatever sense the latter term is used. When normal signifies typical, abnormal means unusual, lying outside the range of common occurrence. When normal signifies a mean or median value, abnormal implies a deviation, however slight, from the mean or median. Compare anomalous.
