In hydrology, a line on a map connecting all points at which there exists an equal vertical distance between the earth's surface and the water table, or equal depths to the upper or lower surface of an aquifer.
Industry:Weather
A line or surface showing the depths in the ground at which points have the same temperature. Isogeotherms are often drawn against coordinates of time and depth to represent the diurnal or annual variation of soil temperature.
Industry:Weather
A singular point in a streamline field that constitutes the intersection of a convergence line and divergence line. It is analogous to a col in the field of a single-valued scalar quantity.
Industry:Weather
A line or surface showing the depths in the ground at which points have the same temperature. Isogeotherms are often drawn against coordinates of time and depth to represent the diurnal or annual variation of soil temperature.
Industry:Weather
The horizontal pressure gradient per unit mass, −α∇Hp, where α is the specific volume, p the pressure, and ∇H the horizontal component of the del operator. This force acts normal to the horizontal isobars toward lower pressure. It is one of the three important forces appearing in the horizontal equations of motion, the others being the Coriolis force and friction. See pressure force.
Industry:Weather
A snow particle, sometimes covered with rime, without visible crystalline facets; sometimes used as a last category for snow identification.
Industry:Weather
An instrument used to reveal but not necessarily measure the presence of an electrical quantity. It is used to display the output of a sensing element after suitable amplification and modification. In radar the term is used to refer to the cathode-ray oscilloscopes, or other recording devices, where the echoes returned from targets are presented visually or graphically. See radarscope.
Industry:Weather
A snow particle, sometimes covered with rime, without visible crystalline facets; sometimes used as a last category for snow identification.
Industry:Weather
A device for producing work by virtue of a temperature difference. The atmosphere may be considered such a device. See Carnot engine.
Industry:Weather
A code approved by the World Meteorological Organization in which the observable meteorological elements are encoded and transmitted in “words” of five numerical digits length.
