SURFACE BOUNDARY LAYER
The lowest layer of the earth's atmosphere, usually up to 3,300 feet, or one kilometer, from the earth's surface, where the wind is influenced by the friction of the earth's surface and the objects on it.

BOW ECHO
A radar echo signature often associated with severe thunderstorms, especially those that produce wind damage. It is bent outward in a "bow" shape.
There is a thin layer immediately above the earth's surface known as the surface boundary layer (or simply the surface layer).
power-law profile"A formula for the variation of wind with height in the surface boundary layer.
The lowest layer of the earth's atmosphere, usually up to 3,300 feet, or one kilometer, from the earth's surface, where the wind is influenced by the friction of the earth's surface and the objects on it. Related terms: surface boundary layer and ...
The troposphere is characterized by decreasing temperature with height, appreciable vertical wind motion, appreciable water vapor, and weather. Dynamically, the troposphere can be divided into the following layers: surface boundary layer, ...
Wind speeds increase rapidly with altitude, and most anemometers are in the surface boundary layer. A more detailed discussion of the vertical wind profile will be found in Turbulence, as well as below in the section on surface effects.
Also known as a surface boundary layer or boundary layer. FRONT The transition zone or interface between two air masses of different densities, which usually means different temperatures.
