One-Dimensional Atmospheric Boundary Layer Model: Intermittent Wind Shears and Thermal Stability at Night

摘要

A one-dimensional, time-dependent computer model of the atmospheric boundary layer was developed to simulate intermittent turbulence and the near- ground microclimate under nighttime stable conditions. In this study, the model produced several turbulent events (oscillations) through the nighttime period that varied in number, frequency, and strength along the axes of initial geostrophic wind speed. These results were found to be in close agreement with results from several previous observational and theoretical studies of this type. It is suggested, therefore, that the one-dimensional computer model is a useful mathematical representation of the nighttime case that includes intermittency.
