1. In hydrology, the ratio of discharge to the cross-sectional area perpendicular to the flow direction. 2. In hydrology, the ratio of integrated velocity profile to the flow depth.
Industry:Weather
Forecast, intended for aviation, of weather conditions at the surface and at various altitudes for a specific period of time.
Industry:Weather
In radar, the time-averaged power transmitted by an antenna into space. Mathematically, average power is the product of the peak power transmitted, the pulse duration, and the pulse repetition frequency. See transmitted power.
Industry:Weather
Net characteristics when all eddy sizes are considered together; used in boundary layer studies when considering the integral effect of all turbulence scales. An example is the mixing length, which represents an average eddy size.
Industry:Weather
The sum of accumulation and ablation over an ice mass (the mass balance) divided by the total surface area. It is the most useful parameter for summarizing the change in a given glacier or ice sheet.
Industry:Weather
Same as drag coefficient, but averaged over a domain composed of different roughness elements. The process of combining different drag coefficients from neighboring small uniform regions into an average value over a larger heterogeneous area is called aggregation.
Industry:Weather
The average velocity of groundwater particles at a certain part of a saturated geologic material.
Industry:Weather
A climatological term referring to the extreme minimum or extreme maximum extent of the ice edge averaged over any given month or period based on observations over a number of years. The term should be preceded by minimum or maximum.
Industry:Weather
1. Same as arithmetic mean. 2. In a very broad sense, any number lying between the extremes of a set of numbers.
Industry:Weather
The rush of air produced in front of an avalanche of dry snow or in front of a landslide. The most destructive form, the avalanche blast, occurs when an avalanche is stopped abruptly, as in the case of an almost vertical fall into a valley floor. Such blasts may have very erratic behavior, leveling one house without damaging its neighbor.
