A type of disk hardness-gauge, especially useful in relatively soft snow.
Industry:Weather
A type of erosion peculiar to high latitudes and/or high elevations. Specifically, it is land reduction by the processes of intensive frost action, that is, congeliturbation, including soil creep, and supplemented by the erosive actions of running water, moving ice, and other agents.
Industry:Weather
A two-dimensional map of either the speed or of one vector component of current, generally plotted as a contour plot in the x–z plane, where x is horizontal distance and z is vertical distance.
Industry:Weather
A type of air mass with characteristics developed over a large land area that therefore has the basic continental characteristic of relatively low moisture content.
Industry:Weather
A two-conductor constant impedance transmission line consisting of one conductor centered inside and insulated from a second conductor.
Industry:Weather
A topographic depression, such as a valley or basin, filled with cold air. The cold air is heavy, and settles to the bottom of the depression. This air can remain stagnant, trapped by the surrounding higher terrain, resulting in long periods of poor air quality and fog, depending on the sources of pollution and amount of moisture in the air, respectively.
Industry:Weather
A thunderstorm attending a cold front. Formerly, the term was also applied to one of the line of thunderstorms that often appears up to a few hundred miles in advance of the cold front, along what is now known as an instability line or squall line.
Industry:Weather
A thorough, quantitative description of climate, particularly with reference to the tables and charts that show the characteristic values of climatic elements at a station or over an area. The term often has a comparative geographic connotation. Like descriptive climatology, it is sometimes used antithetically to climatology, when the latter is narrowly used to denote only the explanation of the causes for climatic conditions. See physical climate.
Industry:Weather
A thermometer consisting of a clock mechanism the speed of which is a function of temperature. It automatically calculates the mean temperature.
Industry:Weather
A thermodynamic diagram for the atmosphere used for studying cloud processes. One conserved variable representing heat or temperature is usually plotted along the abscissa, while the another conserved variable representing the conservation of water is plotted along the ordinate. The variables are chosen to be those that are conserved for both saturated and unsaturated motion. Examples of conserved variables are equivalent potential temperature θe, liquid water potential temperature θL, moist static energy se, liquid water static energy sL, total water mixing ratio rT, saturation point pressure PSP, and saturation point temperature TSP. These variables are not conserved for processes such as precipitation, radiative cooling, and mixing. When a third variable representing height z or pressure P is also indicated in the diagram, then there is enough information to define completely the thermodynamic state and water content of the air. Examples of popular sets of variables are (P, θe,rT), (P, θL, rT), (P, se, rT), (P, sL, rT), and (P, PSP, TSP).
