A type of plant life that requires continuous high temperature and abundant rainfall (in excess of evapotranspiration)
Industry:Weather
A unit of frequency equal to one million (10<sup>6</sup>) cycles per second.
Industry:Weather
Prediction of hydrologic variables such as streamflow or snowmelt for periods three to seven days in advance.
Industry:Weather
A rainbow seen in sea spray. It is optically the same as the ordinary rainbow, although the slightly different index of refraction of saltwater results in a shift in the angular radius of the bow, which is apparent if accompanied by a bow formed in raindrops.
Industry:Weather
A type of filter matched to the known or assumed characteristics of a target signal, designed to optimize the detection of that signal in the presence of noise. Typically such filters are implemented in the temporal or spatial frequency domain, using digital techniques (though analog matched filters are found in radar receivers).
Industry:Weather
An elementary generalization of the earth's climatic pattern, based entirely upon the annual cycle of the sun's inclination. This early climatic classification recognized three basic latitudinal zones (summerless, intermediate, and winterless), which are now known as the Frigid, Temperate, and Torrid Zones, and which are bounded by the Arctic and Antarctic Circles and the Tropic of Cancer and Tropic of Capricorn. What we now call “mathematical climate” probably corresponds to what was classically considered to be climate (from the Greek word klima, meaning “inclination”). It is sometimes used synonymously with solar climate, but the latter has a more specific theoretical connotation.
Industry:Weather
A water mass that occupies the Eurafrican Mediterranean Sea below a depth of 500 m. It is formed in winter by convection in the Ligurian Sea and the Balearic Basin when very cold Siberian air is channeled through Alpine valleys and descends in a burst known as mistral to cool the sea surface. See deep water.
Industry:Weather
The process whereby solutes are mechanically mixed by velocity variations at the microscopic level during advective transport.
Industry:Weather
A cloud species peculiar to the genus cumulus. See cumulus mediocris, cloud classification.
