The speed and direction determined from tracking clouds in satellite imagery. If the clouds tracked are passive, that is, neither growing nor decaying, then the vector approximates the wind vector.
Industry:Weather
The smoke plume that is emitted from a stack (i.e., chimney) at an industrial facility. The plume is usually buoyant and rises up to a final height depending on its initial buoyancy and momentum and the stratification of the boundary layer.
Industry:Weather
The smallest cloud or portion of cloud that can be resolved by a remote sensing device or other instrument.
Industry:Weather
The small area on the anvil of a convective storm that appears colder than the majority of anvil pixels on an infrared satellite image. The region appears colder because it is associated with an overshooting top that is higher than the mean anvil height. Often an overshooting top is found to be the point of origin of an enhanced “v” signature.
Industry:Weather
The slowly varying aspects of the atmosphere–hydrosphere–land surface system. It is typically characterized in terms of suitable averages of the climate system over periods of a month or more, taking into consideration the variability in time of these averaged quantities. Climatic classifications include the spatial variation of these time-averaged variables. Beginning with the view of local climate as little more than the annual course of long-term averages of surface temperature and precipitation, the concept of climate has broadened and evolved in recent decades in response to the increased understanding of the underlying processes that determine climate and its variability. See also climate system, climatology, climate change, climatic classification.
Industry:Weather
The roughly conical surface representing the rising surface of the water table or piezometric surface surrounding a recharge well.
Industry:Weather
The rising of water from between 200 and 400 m to the surface along coastlines where an alongshore blowing wind has the coast on its left in the Northern Hemisphere or on its right in the Southern Hemisphere. Because the surface currents of the Ekman spiral are deflected offshore in these situations, the surface water is drawn away from the coast, causing the colder water from deeper layers to upwell. The associated lowering of the sea surface temperature results in atmospheric heat loss and modifies the local climate. The upwelled water is also rich in nutrients, and coastal upwelling regions are among the most important fishing regions of the World Ocean. The most important coastal upwelling regions are found in the eastern boundary currents of the subtropical gyres, that is, in the Peru/Chile, California, Benguela, and Canary Currents. The Somali, East Arabian, and South Java Currents develop upwelling on a seasonal basis.
Industry:Weather
The region of the electromagnetic spectrum in which CO2 plays a significant role in the transfer of infrared radiation through the atmosphere. Intense absorption is in the band centered at 14. 7 μm.
Industry:Weather
The reduction of stone to small particles through any natural action such as frost action (crevices formed through alternate freezing and thawing); biochemical action of plants, trees, and organisms growing in rocks; wind corrosion (a natural phenomenon akin to sand blasting); ocean wave action; glacial scouring; and tectonic action (the shearing and jointing of rocks caused by stresses in the earth's crust).
