A Similarity Model for Atmospheric Turbulence Structure In the Planetary Boundary Layer

摘要

The planetary boundary layer, the lowest 1000 meters of the atmosphere, is of special interest because most Army operations and materiel function within it. This layer of air is characteristically turbulent. This property not only affects the overall behavior of the layer, but also directly influences Army operations and materiel. Meaningful measurements of atmospheric turbulence are difficult to obtain, and techniques must be developed for assessing the turbulence structure from simple observations or, in some cases, no observations at all. The report discusses numerical solutions of energy and transport equations in the planetary boundary layer.
