Analysis of stochastic processes for the purpose of estimating the probabilities of rare events. Such analysis is often made difficult by uncertainties in the statistics due to an inherent scarcity of data. In meteorology, extreme value analyses have been performed for the prediction of damaging rain, maximum frost penetration, and extreme winds.
Industry:Weather
Any cyclonic-scale storm that is not a tropical cyclone, usually referring only to the migratory frontal cyclones of middle and high latitudes. Compare subtropical cyclone.
Industry:Weather
In meteorology, typical of occurrences poleward of the belt of tropical easterlies.
Industry:Weather
Worldwide changes of sea level due to the increase in the volume of water in the ocean basins. Volume changes are due to mass increases from melting of grounded ice and thermal expansion or contraction of the oceans as they warm or cool. Over geological time the shape and volume of the ocean basins themselves also evolve.
Industry:Weather
Electromagnetic energy in a specified frequency band originating from sources other than those related to the earth, for example, cosmic or solar radiation.
Industry:Weather
An instrument designed by A. F. Dufton in 1929 to record the warmth of a room from the point of view of comfort. It consists of a blackened hollow copper cylinder heated by a carbon filament and a metal filament lamp, which are controlled by a thermostat to maintain a temperature of 75°F. The power used is interpreted in terms of equivalent temperatures.
Industry:Weather
The layer of a water body that receives sufficient sunlight to support effective photosynthesis.
Industry:Weather
A stormy wind from northeast or north-northeast in Arabia and the Near East. See gregale.
Industry:Weather
Adaptable to a wide range of temperatures. It is used in reference to organisms.
Industry:Weather
A series of satellites designed to study the earth's land, atmosphere, and oceans. The major instruments on ERS are an active microwave instrument, a radar altimeter, and an along-track scanning radiometer. The active microwave instrument operates in three modes: SAR image mode, SAR wave mode, and wind scatterometer mode. The scanning radiometer is made up of two instruments, an infrared radiometer and a microwave sounder. ERS-2 also has a global ozone monitoring experiment. ERS-1 was launched in 1991 and ERS-2 in 1995. Both satellites operate in sun-synchronous, near-polar orbits.
