Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This report examines details of a one-dimensional (1D) atmospheric boundary layer model to establish the proper functioning of its soil, plant, and atmospheric physics. To achieve this goal, I inspect, repair, and modify a computer program that scientists at the Hebrew University, Department of Soil and Water Sciences, gave to me years ago. The computer program was exercised to determine if the model results are stable when initial conditions are changed and to determine whether the results are sensible and generally consistent with observed data. To show this, I present a time series of the modeled surface energy budget and modeled profiles of boundary layer wind speed, potential temperature, and specific humidity for daytime (atmospherically unstable conditions) and for nighttime (atmospherically stable conditions). I compare these results, wherever practical, with observed meteorological data. From these results, I infer how well the transfers of momentum, heat, and moisture from one model layer to the next are characterized. I also present root mean square error and d values, where d is an index of agreement, to summarize the model results and comparison with observed data. From the results, I find that the 1D model is functioning properly in solving for many parameter relationships and is as reliable as the earlier models of this type in predicting the general features of boundary layer development.

Available in PDF, EPUB and Kindle. Book excerpt: Almost half the U.S. population lives along the coast. In another 20 years this population is expected to more than double in size. The unique weather and climate of the coastal zone, circulating pollutants, altering storms, changing temperature, and moving coastal currents affect air pollution and disaster preparedness, ocean pollution, and safeguarding near-shore ecosystems. Activities in commerce, industry, transportation, freshwater supply, safety, recreation, and national defense also are affected. The research community engaged in studies of coastal meteorology in recent years has made significant advancements in describing and predicting atmospheric properties along coasts. Coastal Meteorology reviews this progress and recommends research that would increase the value and application of what is known today.

Available in PDF, EPUB and Kindle. Book excerpt: This paper presents an efficient two-dimensional time-dependent one-layer boundary layer model designed specifically for use in general circulation models. Two fundamental problems associated with the boundary layer parameterization are examined using the one-dimensional version of the model. These are the effects of different PBL parameterization schemes and different flux profiles on the model wind and temperatures. This paper concludes that the effect of different PBL parameterization is very significant on temperature calculation but less important on the wind speed. In general, the use of linear flux profiles for the vertical divergence of momentum, heat and moisture is found to be satisfactory. We conclude this study by testing the validity of our two-dimensional model by comparing it with multi-level boundary layer model results. For this purpose, a numerical integration was done to simulate a stably stratified air flow passing from smooth to rough surfaces. (Author).
