Prevailing winds are strongly influenced by Earth's overall atmospheric circulation, in addition to smaller-scale and shorter-lived weather phenomena. In meteorology, prevailing wind in a region of the Earth's surface is a surface wind that blows predominantly from a particular direction. The dominant winds are the trends in direction of wind ...
Thermal comfort as a "condition of mind" is defined in psychological terms. Among the factors that affect the condition of mind (in the laboratory) are a sense of control over the temperature, knowledge of the temperature and the appearance of the (test) environment.
Flying insects, a subset of arthropods, are swept along by the prevailing winds, [133] while birds follow their own course taking advantage of wind conditions, in order to either fly or glide. [134] As such, fine line patterns within weather radar imagery, associated with converging winds, are dominated by insect returns. [135]
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
The simplest definition of socially necessary labour time is the amount of labour time performed by a worker of average skill and productivity, working with tools of the average productive potential, to produce a given commodity. This is an "average unit labour-cost", measured in working hours.
According to the Oxford English Dictionary, the base climate comes from the Middle French climat, which was first used to describe a region's prevailing weather conditions around 1314. [1] One of the first recorded uses of climate as a description of prevailing political attitudes was in The Vanity of Dogmatizing by Joseph Glanvill in 1661 ...
In 1994, the AASHTO Green Book [1] defined the operating speed as "the highest overall speed at which a driver can travel on a given highway under favorable weather conditions and under prevailing traffic conditions without at any time exceeding the safe speed as determined by the design speed on a section-by-section basis," a definition which ...
Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. [1] On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, [2] [3] just below the stratosphere.
