One-celled plants, usually algae, that live in snow and ice and tint their habitat red or green.
Industry:Weather
One of four characteristic properties of solutions, namely, the interdependent changes in vapor pressure, freezing point, boiling point, and osmotic pressure, with a change in dissolved matter. If, under a given set of conditions, the value for any one property is known, the others may be computed. In general, with an increase in dissolved matter (e.g., salt in water), freezing point and vapor pressure decrease, and boiling point and osmotic pressure increase.
Industry:Weather
Minimum and maximum temperatures that define limits of growth and development of an organism, and an optimum temperature at which growth proceeds with greatest rapidity. Cardinal temperatures may vary with the stage of development.
Industry:Weather
Often used interchangeably with cloud drop. When used together, a cloud droplet is considered smaller and falling more slowly than a cloud drop; a cloud drop may grow by coalescence with cloud droplets.
Industry:Weather
One of a set of specified ideograms that represent the various cloud types of greatest significance or those most commonly observed. Cloud symbols are entered on a weather map as part of a station model.
Industry:Weather
Long-term observations of those quantities that describe the state of the earth's surface and atmosphere (e.g., temperature, pressure, precipitation) or climate forcing functions (e.g., solar output, atmospheric carbon dioxide concentrations).
Industry:Weather
Method that allows the height of a cloud base or top to be determined. See ceilometer.
Industry:Weather
Literally, the “wind countess”; a formation of one or more lenticular clouds above and alee of Mount Etna in Sicily. When more than one cloud is present, they are vertically stacked. See la serpe.
Industry:Weather
List of the standard crops of a region in the form of a calendar giving the average dates of sowing and various stages of their growth to harvest.
Industry:Weather
Lines or surfaces associated with a partial differential equation, or with a set of such equations, which are at all points tangent to characteristic directions, determined by certain specified linear combinations of the equations. The use of these lines or surfaces may facilitate the solution of the equations and is known as the method of characteristics. The method has been particularly successful, for example, in the problem of finite-amplitude expansion and shock waves, and the analogy between certain of these flows and a traveling disturbance on an inversion has been studied by meteorologists.
