On the Diagnosis and Conservation of Energy During Condensation
Publisher: American Meteorological Society
Abstract: The diagnosis and conservation of energy during condensation is examined. It is shown that the latent enthalpy, when defined in conjunction with the individual enthalpies of water vapor and liquid water, cannot be a function ...
A Numerical Simulation of Fog Dissipation Using Passive Burner Lines. Part I: Model Development and Comparison with Observations
Publisher: American Meteorological Society
Abstract: A two-dimensional model is developed to simulate dissipation of fog using passive burner lines under either cross-wind or no-wind conditions. The vorticity model developed by Murray (1970) forms the basis for the development. ...
A Numerical Simulation of Fog Dissipation Using Passive Burner Lines. Part II: Sensitivity Experiments
Publisher: American Meteorological Society
Abstract: A two-dimensional model (Tag, 1979) is used to perform sensitivity experiments simulating fog dissipation using passive burner lines under both cross-wind and no-wind conditions. For a cross-wind experiment, heat output ...
A Numerical Simulation of Warm Fog Dissipation by Electrically Enhanced Coalescence: Part I. An Applied Electric Field
Publisher: American Meteorological Society
Abstract: It has been suggested that the use of charged particles or electric fields be considered as a technique for dissipating warm fogs. The study presented here attempts to determine the degree of improvement one could expect ...
A Numerical Simulation of Warm Fog Dissipation by Electrically Enhanced Coalescence: Part II. Charged Drop Seeding
Publisher: American Meteorological Society
Abstract: A numerical study of the use of highly charged water drops to clear warm fog has been conducted. The mechanism studied is the polarization of neutral fog droplets and their capture by the charged drops. A multi-level ...
An Examination of the Breakup of Marine Stratus: a Three-Dimensional Numerical Investigation
Publisher: American Meteorological Society
Abstract: Cloud top entrainment instability, as a mechanism for the breakup of marine stratus, is examined with a three-dimensional, planetary boundary layer (PBL) model. Specifically, we examine the criterion developed by Randall ...
Toward Automated Interpretation of Satellite Imagery for Navy Shipboard Applications
Publisher: American Meteorological Society
Abstract: The U.S. Navy has plans to develop an automated system to analyze satellite imagery aboard its ships at sea. Lack of time for training, in combination with frequent personnel rotations, precludes the building of extensive ...
Accuracy and Energy Conservation in a Three-Dimensional Anelastic Model
Publisher: American Meteorological Society
Abstract: Accuracy and energy conservation are examined in a three-dimensional (3D) anelastic model. For both dry and moist (noncondensing) atmospheres, we prescribe analytic solutions of momentum, potential temperature and mixing ...
Improved Detection of Hotspots using the AVHRR 3.7-um Channel
Publisher: American Meteorological Society
Abstract: The 3.7-?m channel on-board the National Oceanic and Atmospheric Administration's (NOAA) Advanced Very High Resolution Radiometer (AVHRR) provides the unique capability to detect small, but hot, surface features. We present ...
