As a result, smoke plumes emitted into the RL tend to disperse at equal rates in the vertical and lateral directions, creating a cone-shaped plume.
Figure 1. Smoke emissions into the stable air fan out in the horizontal with little vertical dispersion other than wavelike OScillations.
Smoke emissions in the neutral residual-layer air spread with an almost equal rate in the vertical and horizontal, allowing the smoke plume to assume a cone-like shape. Sometimes gaseous chemicals may react to form aerosols or particulates which can precipitate out. The RL often exists for a while in the mornings before being entrained into the new ML. During this time solar radiation may trigger photochemical reactions among the constituents in the RL.
Moisture often behaves as a passive tracer.
Each day, more moisture may be evaporated into the ML and will be retained in the RL. During succeeding days, the re- entrainment of the moist air into the ML might allow cloud formation to occur where it otherwise might not. Variables such as virtual potential temperature usually decrease slowly during the night because of radiation divergence.
The cooling rate is more-or-less uniform throughout the depth of the RL, thus allowing the RL virtual potential temperature profile to remain nearly adiabatic. The RL does not have direct contact with the ground.
During the night, the nocturnal stable layer gradually increases in thickness by modifying the bottom of the RL. Thus, the remainder of the RL is not affected by turbulent transport of surface-related properties and hence does not really fall within our definition of a boundary layer.
IN ADDITION TO READING ONLINE, THIS TITLE IS AVAILABLE IN THESE FORMATS:
Nevertheless, we will include the RL in our studies as an exception to the rule. This is characterized by statically stable air with weaker, sporadic turbulence. Although the wind at ground level frequently becomes lighter or calm at night, the winds aloft may accelerate to supergeostrophic speeds in a phenomenon that is called the low-level jet or nocturnal jet.
The statically stable air tends to suppress turbulence, while the developing nocturnal jet enhances wind shears that tend to generate turbulence.
As a result, turbulence sometimes occurs in relatively short bursts that can cause mixing throughout the SBL.
During the non turbulent periods, the flow becomes essentially decoupled from the surface. The top of the ML is defined as the base of the stable layer, while the SBL top is defined as the top of the stable layer or the height where turbulence intensity is a small fraction of its surface value.
Pollutants emitted into the stable layer disperse relatively little in the vertical. They disperse more rapidly, or "fan out", in the horizontal.In both cases, it worked flawlessly. Enter your email address below and we will send you your username.
Therefore, the book is useful to beginning graduate students as well as established scientists. During the night, the nocturnal stable layer gradually increases in thickness by modifying the bottom of the RL.

The resulting layer of air is sometimes called the residual layer because its initial mean state variables and concentration variables are the same as those of the recently-decayed mixed layer. Convective conditions promote rapid growth; thus, the IBL depth quickly reaches the existing capping inversion. First published: Substantial hydrostatic stability modulation of stress and surface wind fields has also been observed in association with sea surface temperature variations typical of coastal regions.
