Measurements of Overwater Diffusion: The Separation of Relative Diffusion and Meander
(American Meteorological Society, 1987)Data compiled from surface releases of SF6 gas in a purely overwater environment are used in an attempt to parameterize both relative and single-particle diffusion in the lateral direction. Relative diffusion is found to ... -
An Evaluation of Alternatives to the Retrieval Methods Used in Processing FGGE Level II TIROS-N Soundings
(American Meteorological Society, 1987)Alternatives to the retrieval techniques applied by NESDIS operations to derive the FGGF Level IIa soundings are examined. A physical iterative retrieval technique is compared to the operational statistical method, and the ... -
Analysis of Recording Raingage Data for the Israeli II Experiment. Part II: Differential Day and Night Effects of Cloud Seeding
(American Meteorological Society, 1987)This paper reports separate analyses of daytime and nighttime precipitation based on data from recording raingages of the second Israeli randomized experiment. These analyses seemed important because there are a number of ... -
A Climatology of Mean Monthly Snowfall for the Conterminous United States: Temporal and Spatial Patterns
(American Meteorological Society, 1987)Mean monthly snowfall data for 216 stations across the conterminous United States were analyzed to produce a climatology that identifies statistical, spatial and intraseasonal aspects. Geographic variations in the length ... -
Characteristics of Radar-Identified Big Drop Zones in Swiss Hailstorms
(American Meteorological Society, 1987)The characteristics of the so-called ?radar-identified big drop zones? (rBDZ) have been investigated. The study employs radar observations of several thunderstorms and simultaneous microphysical and vertical wind measurements ... -
The Relationship between Incident and Double-Way Transmittances: An Application for the Estimate of Surface Albedo from Satellites over the African Sahel
(American Meteorological Society, 1987)The inference of surface reflectance from satellite observations requires the knowledge of the double-way transmittance through the atmosphere. Since the existing pyranometer networks routinely provide measurements of the ... -
Determination of Cloud Ice Water Content and Geometrical Thickness Using Microwave and Infrared Radiometric Measurements
(American Meteorological Society, 1987)Cloud ice water content and cloud geometrical thickness have been determined using a combination of near-infrared, thermal infrared and thermal microwave radiometric measurements. The radiometric measurements are from a ... -
Doppler Sodar Analysis of Frontal Friction in Relation to Frontal Slope
(American Meteorological Society, 1987)Doppler sodar information on the wind field in relation to frontal slope observed on reflectivity facsimile records was considered during Mesogers 84 experiment. The data have been analyzed to examine and quantify the ... -
Analysis of Recording Raingage Data for the Israeli II Experiment. Part I: Effects of Cloud Seeding on the Components of Daily Rainfall
(American Meteorological Society, 1987)Earlier Published analyses of the second Israeli randomized experiment (1969?75) were restricted to 24-h data; this paper provides more details which are based on continuous time data from recording raingages. The present ... -

On the Prediction of India Monsoon Rainfall Anomalies
(American Meteorological Society, 1987)A complex of anomalies in the premonsoon large-scale circulation setting heralds the interannual variability of India summer monsoon rainfall. The most prominent precursors of precipitation anomalies are the latitude ... -
Coincident Lidar and Aircraft Observations of Entrainment into Thermals and Mixed Layers
(American Meteorological Society, 1987)Coincident observations of the daytime convective boundary layer over Oklahoma were made with the NCAR Queen Air aircraft and the University of Wisconsin ground-based lidar. The two data sets have been merged to provide a ... -
Numerical Modeling of Hailstorms and Hailstone Growth. Part III: Simulation of an Alberta Hailstorm—Natural and Seeded Cases
(American Meteorological Society, 1987)This paper reports on simulations of a multicellular hailstorm case observed during the 1983 Alberta Hail Project. The field operations on that day concentrated on two successive feeder cells which were subjected to ... -
Convectivc Elements in the Marine Atmospheric Boundary Layer. Part II: Entrainment at the Capping Inversion
(American Meteorological Society, 1987)Data from two aircraft flights in the marine atmospheric boundary layer are analyzed in an investigation of entrainment processes at the top of the well-mixed layer. Both days had strong wind shear across the inversion, ... -
The Representation of Atmospheric Motion in Models of Regional-Scale Air Pollution
(American Meteorological Society, 1987)A method is developed for generating ensembles of wind fields for use in regional scale (1000 km) models of transport and diffusion. The underlying objective is a methodology for representing atmospheric motion in applied ... -
Convective Elements in the Marine Atmospheric Boundary Layer. Part I: Conditional Sampling Statistics
(American Meteorological Society, 1987)The properties of updrafts and downdrafts through the entire depth of the marine atmospheric boundary layer are investigated using conditional sampling based on an indicator function derived from the vertical velocity time ... -
Two Case Studies of the Transport of Dust Storm Aerosol and the Potential for Incorporation into Precipitation
(American Meteorological Society, 1987)To investigate the hypothesis that dust storms enhanced the calcium concentrations in precipitation in the mid-1950s, two case studies were performed for major dust events in the southern Plains of the United States during ... -
Assimilation of Scalar Versus Horizontal Gradient Information from the VAS into a Mesoscale Model
(American Meteorological Society, 1987)Comparisons are made between analyses and forecasts which incorporate VAS geopotential data as either scalar or horizontal gradient information for a mw study on the AVE/VAS day of 6 March 1982. On this day, incorporating ... -
Severe Storm Identification with Satellite Microwave Radiometry: An Initial Investigation with Nimbus-7 SMMR Data
