Abstract: A method is presented to estimate the vertical extent of atmospheric mixing during the afternoon and the average transport wind speed, i.e., the average wind speed within the mixing layer. Afternoon mixing depth is assumed ...

Abstract: Forecasts of air pollution potential by semi-objective means are demonstrated and shown to be useful in delineating stagnation areas associated with the quasi-stationary anticyclone and ridge aloft over the western United ...

Abstract: Previous studies of changes in visibility over a period of years have indicated either a general trend toward better horizontal visibilities or no change. In this study, visibility, relative humidity, wind direction, and ...
