PLANETARY BOUNDARY LAYER

Specialty Definition: PLANETARY BOUNDARY LAYER

DomainDefinition

Aerospace

That layer of the atmosphere from a planet's surface to the geostrophic wind level including, therefore, the surface boundary layer and the Ekman layer. Above this layer lies the free atmosphere. Also called friction layer, atmospheric boundary layer. (references)

Science

The turbulent layer of atmosphere occupying the lowest few hundred meters of the atmosphere. (references)

Weather

The transition region between the turbulent surface layer and the normally nonturbulent free atmosphere. This region is about 1 km in thickness and is characterized by a well-developed mixing generated by frictional drag as the air masses move over the Earth's surface. This layer contains approximately 10% of the mass of the atmosphere. Also called the atmospheric boundary layer or frictional layer. (references)
