The time of the successive rise and decline of a water table, over a day, year, or longer time period.
Industry:Weather
The time it takes the earth to complete one full orbit around the sun relative to the fixed stars.
Industry:Weather
The time interval from midnight to midnight, with midnight being the sun's transit across the lower meridian.
Industry:Weather
The time beyond which it is no longer possible to predict the state of a system, given knowledge of current and past states, with a desired level of accuracy.
Industry:Weather
The theory that the changes of climate through geologic time (the paleoclimates) have been due to changes of land and sea distribution and orography combined with fluctuations of solar radiation of the order of 10%–20% on either side of the mean. Topographic changes may account for the occurrence of ice ages as a whole, but not for the more rapid alternations of glacial and interglacial periods. A combination of the topographic with the solar fluctuations seems to offer a nearly complete explanation of climatic changes, but it is not yet clear which plays the main part.
Industry:Weather
The term for solid or liquid particles found in the air. Some particles are large or dark enough to be seen as soot or smoke. Others are so small they can be detected only with an electron microscope. Because particles originate from a variety of mobile and stationary sources, their chemical and physical compositions vary widely. Particulate matter can be directly emitted or can be formed in the atmosphere when gaseous pollutants such as sulfur dioxide (SO<sub><sub>2</sub></sub>) and NO<sub><sub>x</sub></sub> react to form fine particles. See aerosol.
Industry:Weather
The temporal and spatial statistics of radar weather echoes. See radar meteorology, radio climatology.
Industry:Weather
The term applied to toxic algal blooms caused by several genera of dinoflagellates (Gymnodinium and Gonyaulax) that turn the sea red and are frequently associated with a deterioration in water quality. The color occurs as a result of the reaction of a red pigment, peridinin, to light during photosynthesis. These toxic algal blooms pose a serious threat to marine life and are potentially harmful to humans. The term has no connection with astronomical tides. However, its association with the word “tide” is from popular observations of its movements with tidal currents in estuaries.
Industry:Weather
The temperature measured at a given soil depth, typically at 2, 4, 8, and sometimes 20 and 40 in. Many biological processes, including seed germination, plant emergence, microbial activity, and soil respiration are a function of soil temperature.
