1. Force of the wind on a structure, object, etc. , proportional to the square of wind speed. 2. Number on a progressive scale (Beaufort wind scale) corresponding to the effects produced by winds between a particular range of speeds.
Industry:Weather
1. For a set of data arranged in order, values that partition the data into three groups, each containing one-third of the total number of observations. 2. Values of a random variable that partition the variable range into three subintervals in such a way that the probability taken over each subinterval is equal to one-third.
Industry:Weather
1. Extension, usually of a fixed volume, in the direction of the local vertical. 2. A process in which ascending vertical motion of air increases with altitude, or descending motion decreases with (increasing) altitude.
Industry:Weather
1. Any portion of the earth characterized by a tropical climate. 2. Same as Torrid Zone. See Tropic of Cancer, Tropic of Capricorn.
Industry:Weather
1. According to general international usage, a change in wind direction in a clockwise sense (e.g., south to southwest to west) in either hemisphere of the earth; the opposite of backing. 2. According to widespread usage among U. S. Meteorologists, a change in wind direction in a clockwise sense in the Northern Hemisphere, counterclockwise in the Southern Hemisphere; the opposite of backing.
Industry:Weather
1. Amount of heat transported by a river or canal per unit time (Joules per second). 2. Amount of heat discharged by an outlet into a water body per unit time (Joules per second).
Industry:Weather
1. An analog voltage produced by a sensor and conveying information, often with some information parameter varying periodically with time. 2. In imaging systems, a voltage representing image intensity as a function of position in the image. 3. In radar or lidar, the signal produced by the detection system, usually conveying the signal intensity as a function of range.
Industry:Weather
1. Abbreviation for temperature–humidity index. 2. Abbreviation for time–height indicator.
Industry:Weather
1. A wind directed up a slope, often used to describe winds produced by processes larger in scale than the slope. Because this flow produces rising atmospheric motion, upslope winds experience cooling, increasing relative humidity, decreasing stability, and, if sufficient moisture is present, the formation of fog, clouds, and precipitation. 2. Flow directed up a mountain slope and driven by heating at the earth's surface under light larger-scale flow conditions; a component of the mountain–valley or mountain–plains wind systems; same as anabatic wind.
