A sensor that determines water level by pumping gas into a reservoir and measuring the changes in pressure.
Industry:Weather
A series of numbers from 0 to 12 indicating the state of the wind and sea.
Industry:Weather
A set of functions that can be linearly combined to form a more general set of functions.
Industry:Weather
A sea surface wave that has become too steep to be stable and that breaks on the shore or in the open ocean. Breakers can be classified into four categories: 1) A spilling breaker breaks gradually over a considerable distance; 2) plunging breakers tend to curl over and break with a crash; 3) surging breakers peak up, but then instead of spilling or plunging, they surge up on the beach face; 4) collapsing breakers break in the middle or near the bottom of the wave rather than at the top.
Industry:Weather
A representation of the atmospheric density actually encountered by a projectile in flight, expressed as a percentage of the density according to the standard artillery atmosphere. Thus, if the actual density distribution produced the same effect upon a projectile as the standard density distribution, the ballistic density would be 100%.
Industry:Weather
A representation of a tropical vortex based on a blend of observed surface winds and typical tropical storm wind profiles. Because of limited observations and coarse model resolution for the production of background fields, tropical cyclones are often poorly resolved in operational analyses. To alleviate this problem, a bogus vortex can be used in the analysis of tropical cyclones both in global data assimilation systems and for initial conditions of limited area, high-resolution hurricane models.
Industry:Weather
A relative number related to the contribution that fire behavior makes to the amount of effort needed to contain a fire of a specified fuel type. The calculated burning index falls on a scale of 1–100: 1–11 is no fire danger; 12–35 is medium danger; 40–100 is high danger. See fire-danger meter.
Industry:Weather
A reference against which measurements may be evaluated, for instance, a runoff- measuring station established as representative or typical of a hydrologic region to provide a continuing series of hydrological observations that are relatively uninfluenced by past or future artificial changes.
Industry:Weather
A recording barometer. Barographs may be classified, on the basis of their construction, into the following types: 1) aneroid barograph (including microbarograph); 2) float barograph; 3) photographic barograph; and 4) weight barograph. The aneroid barograph is the one most commonly used in weather stations.
Industry:Weather
A plot of relative concentration of a given substance versus time where relative concentration is defined as the ratio of the actual concentration to the source concentration.
