A current that is proportional to the voltage and inversely proportional to the resistance.
Industry:Weather
A layer of oil on the water surface, usually as a result of an accidental or deliberate spill of crude oil or other petroleum product. The thickness of an oil slick can range from a few molecules thick up to many millimeters. Thin oil slicks appear as a “blue sheen”, due to optical interference effects. Even when very thin, slicks cause significant damping of centimeter-scale surface waves and thus appear as low-backscatter regions in airborne or satellite radar images. After spillage, oil slicks spread by the effects of the winds, tides, gravity, surface tension, and ocean current shear and turbulence. They eventually disperse by evaporation, dissolution, and downmixing by breaking waves. Wave action can also lead to the formation of oil-in-water emulsions.
Industry:Weather
Deposited snow in which the original crystalline forms are no longer recognizable, such as firn, spring snow.
Industry:Weather
Wind blowing from land to sea. During synoptic conditions of light winds, offshore winds near the surface often occur at night as a component of the land breeze.
Industry:Weather
Any aircraft course or track that does not lie within the bounds of prescribed airways.
Industry:Weather
A unit of magnetic field intensity equal to one dyne per cgs unit magnetic pole. See gauss.
Industry:Weather
The chemical species that contain an odd number of oxygen atoms, that is, chiefly atomic oxygen (O) and ozone (O<sub>3</sub>).
Industry:Weather
The sum of the concentrations of oxygen atoms and ozone (O<sub>3</sub>). In the lower atmosphere, the concentration of O<sub>3</sub> greatly exceeds that of O, and the odd oxygen level can be approximated by the O<sub>3</sub> concentration. See Chapman mechanism.
Industry:Weather
A collective term for the suite of inorganic chlorine compounds found in the atmosphere, including chlorine atoms (Cl), chlorine monoxide (ClO), hydrogen chloride (HCl), chlorine nitrate (ClNO<sub>3</sub>), hypochlorous acid (HOCl), and chlorine monoxide dimer (Cl<sub>2</sub>O<sub>2</sub>). The interconversion of these compounds in the stratosphere leads to ozone depletion.
