Any weakening of anticyclonic circulation in the atmosphere; the opposite of anticyclogenesis. Anticyclolysis (which refers to the circulation) should be distinguished from deepening (which refers to the atmospheric pressure), although the two processes usually occur together. Compare cyclolysis.
Industry:Weather
Any strengthening or development of anticyclonic circulation in the atmosphere; the opposite of anticyclolysis. This applies to the development of anticyclonic circulation (or the initial appearance of a high) where previously it was nonexistent, as well as to intensification of existing anticyclonic flow. The most common application of this term is to the formation of a new anticyclone. Care should be taken, however, to distinguish the increase in anticyclonic circulation from the increase in atmospheric pressure (filling), although they usually occur simultaneously. Compare cyclogenesis.
Industry:Weather
An extension of the crepuscular rays across the sky toward the antisolar point. Anticrepuscular rays seen with a rainbow or fogbow will always be radii to the bow.
Industry:Weather
Heat released to the atmosphere as a result of human activities, often involving combustion of fuels. Sources include industrial plants, space heating and cooling, human metabolism, and vehicle exhausts. In cities this source typically contributes 15–50 W m−2 to the local heat balance, and several hundred W m−2 in the center of large cities in cold climates and industrial areas. Compare urban heat island.
Industry:Weather
Emissions to the atmosphere of gases as a result of human activity. The term is often used to describe, but is not restricted to, the exhaust from combustion events.
Industry:Weather
Human-induced or resulting from human activities; often used to refer to environmental changes, global or local in scale.
Industry:Weather
Climate change that occurs as a result of human activities.
Industry:Weather
A luminous white spot that appears on the parhelic circle 180° in azimuth away from the sun. The origin of anthelion is not settled. The brightness of this spot may be due partly to the superposition of the parhelic circle and of the anthelic arcs, which intersect the parhelic circle at this point. Other candidate mechanisms giving light to anthelion have been suggested.
Industry:Weather
A group of halos, each of which passes through the anthelion. Four mechanisms have been proposed for producing arcs of various shapes that nevertheless pass through the anthelion. Each of the four predicted shapes has been documented photographically. Each mechanism involves refraction and internal reflection in columnar ice crystals, but they differ in the particular crystal faces involved.
