In atmospheric electricity, the sum of the electrical conductivities of the positive and negative ions found in a given portion of the atmosphere.
Industry:Weather
In a psychrometer, the thermometer that has the wet, muslin-covered bulb, and, therefore measures wet-bulb temperature.
Industry:Weather
In a photo image, the frequency of change and arrangement of tones, often due to highlights and shadows created by the irregular surface being viewed.
Industry:Weather
Ice with a white appearance caused by the occurrence of bubbles within the ice. The bubbles increase the scattering of all wavelengths of light in contrast to the appearance of bubble-free blue ice.
Industry:Weather
Ice modified by exposure to weather; usually applied to polar ice where melting does not occur, such as blue ice areas of Antarctica.
Industry:Weather
Horizontal motion in the oceanic surface layer driven by the wind stress. A rough estimate of wind drift is 3% of the wind speed, about 10° to the right (left) of the wind direction in the Northern (Southern) Hemisphere.
Industry:Weather
Generally, the climate that produces tundra vegetation; it is too cold for the growth of trees but does not have a permanent snow–ice cover. In W. Köppen's 1936 climatic classification it is one of the polar climates, defined as having a mean temperature for the warmest month of less than 10°C (50°F) (in contrast to snow forest and temperate rainy climates) but higher than 0°C (32°F) (which is the limit of perpetual frost climate). Tundra is designated ''ET''. Tundra climate appears as a temperature province in C. W. Thornthwaite's 1931 classification.
Industry:Weather
German expression (literally, “forest death”) for the forest dieback or decline usually associated with the effects of acid rain.
Industry:Weather
Generally, the discharge of water heated by industrial processes into natural water bodies. Also, the “waste heat” generated by industrial processes, such as those associated with petrochemical facilities, coke ovens, and flares, that result in large “plumes” of heated ambient air released into the atmosphere.
