Clouds within a deformation zone in the wind field. These clouds undergo elongation in one direction and contraction in the perpendicular direction. Often clouds evaporate on one side of the elongation axis producing a smooth cloud boundary.
Industry:Weather
A region of the atmosphere where the stretching or shearing deformation is large. See deformation.
Industry:Weather
A thermometer using transducing elements that deform with temperature. Examples of deformation thermometers are the bimetallic thermometer and the Bourdon tube type of thermometer.
Industry:Weather
Usually, the major axis along which deformation (stretching, compression) occurs.
Industry:Weather
In geology, the removal of loose soil and other surface material by the wind, leaving the rocks bare to the continuous attack of the weather. Deflation is usually the factor responsible for the frequently stony cover of desert surfaces, sometimes called “desert pavement. ”
Industry:Weather
(Abbreviated DGRF. ) A mathematical model of the geomagnetic field for a time in the past. It is to be distinguished from the International Geomagnetic Reference Field (IGRF), which is for the present time.
Industry:Weather
A series of polar orbiting sun- synchronous satellites operated by the U. S. Department of Defense. The first in the series (DMSP Block 4) was launched in September 1966. The current DMSP instrument payload includes the OLS, SSM/I, and SSM/T.
Industry:Weather
A British term for decrease with time of the central pressure of a depression.
Industry:Weather
A decrease in the central pressure of a pressure system as depicted on a constant- height chart, or an analogous decrease in height on a constant-pressure chart; the opposite of filling. The term is usually applied to low pressure rather than to high pressure, although technically it is acceptable in either sense. The deepening of a low is commonly accompanied by the intensification of its cyclonic circulation, and the term is frequently used to imply the process of cyclogenesis. Deepening can be quantitatively expressed in at least two ways: either 1) as the time rate of central-pressure decreases; or 2) as that component of the pressure tendency at any fixed point that is attributable neither to the motion of the pressure system relative to that point nor to the diurnal influence of atmospheric tides. Compare cyclogenesis.
