The Potential of a Spaceborne Cloud Radar for the Detection of Stratocumulus Clouds
(American Meteorological Society, 1997)The radar reflectivity and liquid water content of stratocumulus clouds have been computed from cloud droplet spectra recorded during more than 4000 km of cloud penetrations by an aircraft, and the probability of detecting ... -
Rainfall Anomaly over the Lee Side of Mount Carmel (Israel) and the Associated Wind Field
(American Meteorological Society, 1997)Yagur and other rain gauge stations located on the lee side of Mount Carmel in Israel experience much higher amounts of precipitation than those measured on the windward side of the mountain at a similar altitude and more ... -
Model-Simulated Influences of Shelterbelt Shape on Wind-Sheltering Efficiency
(American Meteorological Society, 1997)The authors report results of a numerical model used to simulate wind and turbulence fields for porous, living shelterbelts with seven different cross-sectional shapes. The simulations are consistent with results of Woodruff ... -
Some Recent Long-Range Diffusion Observations
(American Meteorological Society, 1995)Recent atmospheric cloud-spreading (relative diffusion) data from a variety of sources are combined to show that the horizontal spreading rate is approximately linear over a time range from 1 to 10 or more hours (20?200 ... -
Trajectories for Saharan Dust Transported to Barbados Using Stokes's Law to Describe Gravitational Settling
(American Meteorological Society, 1995)Atmospheric chemistry programs often make use of retrospective back trajectories to determine the source regions of substances sampled at a particular site. Isentropic trajectories, which depict motion on hypothetical ... -
Large-Scale Analysis of Cirrus Clouds from AVHRR Data: Assessment of Both a Microphysical Index and the Cloud-Top Temperature
(American Meteorological Society, 1997)An algorithm that allows an automatic analysis of cirrus properties from Advanced Very High Resolution Radiometer (AVHRR) observations is presented. Further investigations of the information content and physical meaning ... -
Variability of Microphysical Parameters in High-Altitude Ice Clouds: Results of the Remote Sensing Method
(American Meteorological Society, 1997)The remote sensing method for retrieving vertical profiles of microphysical parameters in ice clouds from ground-based measurements taken by the Doppler radar and IR radiometer was applied to several cloud cases observed ... -
Differential Doppler Velocity: A Radar Parameter for Characterizing Hydrometeor Size Distributions
(American Meteorological Society, 1997)Observations of Doppler-resolved spectra of differential radar reflectivity provide estimates of particle shapes as a function of their terminal velocity, and they can be derived by having the antenna at a significant ... -
Local Advection of Momentum, Heat, and Moisture during the Melt of Patchy Snow Covers
(American Meteorological Society, 1995)A numerical atmospheric boundary layer model, based on higher-order turbulence closure assumptions, is developed and used to simulate the local advection of momentum, heat, and moisture during the melt of patchy snow covers ... -
Evaluation of the Effect of Horizontal Diffusion on the Long-Range Atmospheric Transport Simulation with Chernobyl Data
(American Meteorological Society, 1995)The effect of horizontal diffusion on the long-range transport simulation is examined with a Lagrangian particle transport model. The transport of radioactivity released from Chernobyl is simulated by the model with different ... -
Simulated Urban Climate Response to Modifications in Surface Albedo and Vegetative Cover
(American Meteorological Society, 1995)Three-dimensional meteorological simulations have been conducted to investigate the potential impact of urban surface characteristic modifications on local climate. Results for a base case simulation for the Los Angeles ... -
A Simple Method for Spatial Interpolation of the Wind in Complex Terrain
(American Meteorological Society, 1995)The topographical elevation difference is proposed as a new variable for spatial interpolation of the sparse surface wind measurements to a finer mesh in a complex terrain area. The most used method for the initialization ... -
Meteorological Modeling on High-Ozone Days in Perth, Western Australia
(American Meteorological Society, 1995)The West Australian capital city of Perth is located on a coastal plain between the sea to the west and an escarpment rising to the east. It is isolated from all other cities or sources of pollution. In this study, the ... -
Removal of the Solar Component in AVHRR 3.7-µm Radiances for the Retrieval of Cirrus Cloud Parameters
(American Meteorological Society, 1995)A numerical scheme has been developed to remove the solar component in the Advanced Very High Resolution Radiometer (AVHRR) 3.7-µm channel for the retrieval of cirrus parameters during daytime. This method uses a number ... -
Horizontal Heat Fluxes over Complex Terrain Computed Using a Simple Mixed-Layer Model and a Numerical Model
(American Meteorological Society, 1995)The thermally induced local circulation over a periodic valley is simulated by a two-dimensional numerical model that does not include condensational processes. During the daytime of a clear, calm day, heat is transported ... -
Growth and Decay of Error in a Numerical Cloud Model Due to Small Initial Perturbations and Parameter Changes

A Water Vapor Index from Satellite Measurements
(American Meteorological Society, 1995)A method for deriving a water vapor index is presented. An important feature of the index is the fact that it does not rely on radiosondes. Thus, it is not influenced by problems associated with radiosondes and the extent ... -
