    • On the Measurement of the Transfer of Gases across the Air–Sea Interface 

      Businger, Joost A. (American Meteorological Society, 1997)
      An outline is given of the procedure for obtaining the gas transfer across the air?sea interface when the heat flux from the water to the surface is known. An essential assumption is similarity between the fluxes of heat ...

      Holcombe, Troy Leon; Ley, Trevor; Gillette, Dale A. (American Meteorological Society, 1997)
      A better understanding of the effects of precipitation and source area on blowing dust in the Sonoran Desert has been sought through the study of 1190 dust episodes occurring during the 1948?78 time period at Blythe, ...

    • Modeling Wind Field and Pollution Transport over a Complex Terrain Using an Emergency Dose Information Code SPEEDI 

      Venkatesan, R.; Möllmann-Coers, M.; Natarajan, A. (American Meteorological Society, 1997)
      Atmospheric dispersion code system SPEEDI (System for Prediction of Environmental Emergency Dose Information) has been applied to simulate the field experiments conducted over a complex terrain. A diagnostic mass-consistent ...

    • Complete Urban Surface Temperatures 

      Voogt, J. A.; Oke, T. R. (American Meteorological Society, 1997)
      An observation program using ground and airborne thermal infrared radiometers is used to estimate the surface temperature of urban areas, taking into account the total active surface area. The authors call this the complete ...

    • Analysis of Wind and Turbulence Fields in a Region with Complex Orography 

      Feller, Waldemar; Gassmann, Fritz (American Meteorological Society, 1997)
      In a region of about 1000 km2 with complex orography, 1-h averages of wind and turbulence fields were analyzed over a period of 1 yr. It was shown that spatial homogeneity and temporal stationarity of the wind fields as ...

    • A PDF Dispersion Model for Buoyant Plumes in the Convective Boundary Layer 

      Weil, J. C.; Corio, L. A.; Brower, R. P. (American Meteorological Society, 1997)
      A probability density function (PDF) dispersion model is presented for buoyant plumes in the convective boundary layer (CBL), where the mean concentration field C is obtained from the PDFs py and pz of tracer particle ...

    • The Long Lifetime of the Dispersion Methods of Pasquill in U.S. Regulatory Air Modeling 

      Turner, D. Bruce (American Meteorological Society, 1997)
      The suggestions of Pasquill as set forth in his landmark 1961 Meteorological Magazine paper are briefly reviewed. These methods are viewed from the perspective of the requirements placed upon air agencies after the passage ...

    • EDITORIAL 

      Hanna, Steven R. (American Meteorological Society, 1997)

    • VALDRIFT—A Valley Atmospheric Dispersion Model 

      Allwine, K. Jerry; Bian, Xindi; Whiteman, C. David; Thistle, Harold W. (American Meteorological Society, 1997)
      VALDRIFT (valley drift) is a valley atmospheric transport, diffusion, and deposition model. The model is phenomenological?that is, the dominant meteorological processes governing the behavior of the valley atmosphere are ...

    • Nocturnal Wind Structure and Plume Growth Rates Due to Inertial Oscillations 

      Gupta, Shekhar; McNider, R. T.; Trainer, Michael; Zamora, Robert J.; Knupp, Kevin; Singh, M. P. (American Meteorological Society, 1997)
      Theoretical plume growth rates depend upon the atmospheric spatial energy spectrum. Current grid-based numerical models generally resolve large-scale (synoptic) energy, while planetary boundary layer turbulence is ...

    • Improvements to the EPA Industrial Source Complex Dispersion Model 

      Atkinson, Dennis G.; Bailey, Desmond T.; Irwin, John S.; Touma, Jawad S. (American Meteorological Society, 1997)
      Air quality models are a key component in determining air pollution control requirements. The Industrial Source Complex (ISC2) model is a steady-state Gaussian plume model that is used for modeling point, area, volume, and ...

    • Sensitivity of the Industrial Source Complex Model to Input Deposition Parameters 

      Schwede, Donna B.; Paumier, James O. (American Meteorological Society, 1997)
      The Industrial Source Complex model has recently been revised to include algorithms for estimating dry and wet deposition of particles in addition to air concentration. This study examines the sensitivity of the maximum ...

    • A Three-Parameter PDF for the Concentration of an Atmospheric Pollutant 

      Lewis, D. M.; Chatwin, P. C. (American Meteorological Society, 1997)
      This paper follows on from the work of two previous papers that presented a new model [exponential and a generalized Pareto distribution (EGPD)] for the probability density function of the concentration of a contaminant ...

    • Boundary Layer Parameterization for a Non-Gaussian Puff Model 

      Tirabassi, T.; Rizza, U. (American Meteorological Society, 1997)
      The paper presents two boundary layer parameterizations for a model based on a general technique for solving the K equation using the truncated Gram?Charlier expansion (type A) of the concentration field and a finite set ...
