Satellite imagery that is reformatted into subsections covering specified geographic areas.
Industry:Weather
Response of an organism to the relative duration of dark and light periods. In plants, photoperiodism may affect flower or seed development, vegetative growth, formation of bulbs and tubers, leaf shape, character and extent of branching, abscission (dropping of vegetative growth, i.e., protective seed sheath) and leaf fall, root development, dormancy, and death.
Industry:Weather
Resistance to movement of air flowing along the surface of the earth or other surface such as an airplane wing. The total drag at the surface is a combination of skin drag due to viscosity, form drag due to pressure forces created as the wind hits roughness elements, and gravity wave drag in the case of statically stable air. In the atmosphere, surface friction is related to turbulent drag. Compare friction velocity, drag coefficient, Reynolds stress.
Industry:Weather
Report of ground radar weather observation. These encoded reports and transmitted reports usually give azimuth, distance, altitude, intensity, shape, movement, and other characteristics of precipitation echoes observed by the radar. See'' also'' RAREP.
Industry:Weather
Removal of pollutants from the air by either rain or snow. Rainout (or snowout), which is the in-cloud capture of particulates as condensation nuclei, is one form of scavenging. The other form is washout, the below-cloud capture of particulates and gaseous pollutants by falling raindrops. Large particles are most efficiently removed by washout. Small particles (especially those less than 1 μm in diameter) more easily follow the airstream flowing around raindrops and generally avoid capture by raindrops except in heavy rain events.
Industry:Weather
Ratio of the actual duration of bright sunshine to the geographically or topographically possible duration.
Industry:Weather
Ratio of the net available storage of a reservoir to the annual mean inflow.
Industry:Weather
Rectangular Cartesian coordinates in which the coordinates ''x'', ''y'', and ''z'' are measured along three mutually perpendicular axes such that a rotation of the positive ''x'' axis into the positive ''y'' axis will drive a right-handed screw in the direction of the positive ''z'' axis. The Cartesian coordinates most often used in meteorology form a right-handed system: ''x'' increasing to east, ''y'' to north, ''z'' to zenith.
Industry:Weather
Reduced visibility in the atmospheric boundary layer caused by suspended particles of soil, mixed into the air during strong winds. Sand haze is particularly prevalent in desert regions where there is little moisture and few plants to hold the sand grains to the surface. After a sandstorm the larger sand grains will fall out of the air quickly, leaving a sand haze of medium size particles (1–100 μm diameters, including silt and fine sand) and small particles (< 1 μm diameters, including clay particles). See sandstorm, haboob, aerosol, airborne particulates.
Industry:Weather
Referring usually to an object moving faster than the speed of sound in the gas or liquid surrounding it.
