In general, a layer of air adjacent to a bounding surface Specifically, the term most often refers to the planetary boundary layer (PBL), which is the layer within which the effects of friction are significant For the earth, this layer is considered to be roughly the lowest 1 or 2 kilometers of the atmosphere
the layer of slower flow of a fluid past a surface
The region in the immediate vicinity of a surface in which the phase shift between a direct and a reflected path wave is negligible within the audio frequency spectrum of interest The Pressure Zone
The layer of fluid in the immediate vicinity of a bounding surface, eg sea bottom At the boundary layer the frictional forces are significant and can lead to wave distortion
This is a transitional area between two distinct regions with different physical properties (e g , air and water) In atmospheric modeling, the boundary layer is usually considered to be the layer of air adjacent to the Earth's surface There are basically two ways to represent the boundary layer in a numerical prediction model One way is to provide sufficient levels near the Earth's surface to resolve the boundary layer Another way is to apply boundary layer parameterization methods so that the boundary layer processes can be approximately represented with model variables
The part of the troposphere that is directly influenced by the presence of the Earth's surface, and responds to surface forcings with a timescale of an hour or less
The relatively still layer of water just above the bed of a river
A transition layer between two neighboring regions of plasma in the magnetosphere Some examples are the plasma sheet boundary layer, which is the transition from the plasma sheet to the tail lobes, and the low latitude boundary layer, just inside the magnetopause, which is the transition between the equatorial magnetosphere and the solar wind in the magnetosheath (which is solar wind modified in various ways by the bow shock)
A common interface between two software components that is standardized to allow other components to connect to this interface
In general, a layer of air adjacent to a bounding surface Specifically, the term most often refers to the planetary boundary layer, which is the layer within which the effects of friction are significant For the earth, this layer is considered to be roughly the lowest one or two kilometers of the atmosphere It is within this layer that temperatures are most strongly affected by daytime insolation and nighttime radiational cooling, and winds are affected by friction with the earth's surface The effects of friction die out gradually with height, so the "top" of this layer cannot be defined exactly
the layer of fluid in the immediate vicinity of a bounding surface; in the atmosphere, the air layer near the ground affected by diurnal heat, moisture or momentum transfer to or from the surface
The region of fluid close to the surface of a solid body where, due to viscosity, the transverse gradients of velocity are large compared to horizontal variations and where shear stress is significant
The layer of reduced velocity in fluids, such as air and water, that is immediately adjacent to the surface of a solid past which the fluid is flowing. In fluid mechanics, a thin layer of flowing gas or liquid in contact with a surface (e.g., of an airplane wing or the inside of a pipe). The fluid in the boundary layer is subjected to shear forces. A range of velocities is established across the boundary layer, from zero (provided the fluid is in contact with the surface) to maximum. Flow in boundary layers is more easily described mathematically than is flow in the free stream. Boundary layers are thinner at the leading edge of an aircraft wing and thicker toward the trailing edge; such boundary layers generally have laminar flow in the leading (upstream) portion and turbulent flow in the trailing (downstream) portion.

A layer of air saturated with water vapor (from transpiration) that forms next to a leaf surface when there is no air movement
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
a layer of fluid whose dynamic behavior is directly influenced by an adjacent solid or liquid surface Meteorological examples are the atmospheric boundary layer and the sheath of air enveloping a falling raindrop
A general term for the layer of air adjacent to a surface
Layer of atmosphere directly affected by the earth's surface
The region of the atmosphere below ~3,000 ft (1 km) altitude, where air motion is affected by turbulent interaction with the ground surface Back
