Evaluation of Several “Single-Pass” Estimators of the Mean and the Standard Deviation of Wind Direction
(American Meteorological Society, 1986)Proposed single-pass methods for estimating the mean (D?) and the standard deviation (σd) of wind direction and other problems in wind statistics have been evaluated using extensive field data. It can be concluded that ... -
Delayed Effects of Cloud Seeding with Silver Iodide
(American Meteorological Society, 1986)Apparent delayed effects of aerial cloud seeding with silver iodide are demonstrated in Smith et al.'s experiment in Tasmania. These effects reached a maximum nine days after a seeded day and were most unlikely to have ... -
A High Resolution Spatial and Temporal Multiple Doppler Analysis of a Microburst and Its Application to Aircraft Flight Simulation
(American Meteorological Society, 1986)Multiple Doppler radar data collected during the Joint Airport Weather Studies (JAWS) Project is used to synthesize the three-dimensional wind in the region of a microburst. The particular microburst used in this study is ... -
Analysis of Spatial Inhomogeneities in Cumulus Clouds Using High Spatial Resolution Landsat Data
(American Meteorological Society, 1986)Aircraft observations and high resolution Landsat Multispectral Scanner digital data are used to determine the sizes of spatial inhomogeneities (?holes?) in cumulus clouds. The majority of holes are found near cloud edges, ... -
The Lognormal Fit to Raindrop Spectra from Frontal Convective Clouds in Israel
(American Meteorological Society, 1986)Measurements of rain drop size spectra in Israel were carried out over a period of two years. It is shown that the size distribution can be best described by a lognormal distribution. With its parameters weighted by a ... -
A Statistical Approach of Estimating Vertical Temperature Gradients from Near-Surface Observations
(American Meteorological Society, 1986)A simple method for estimating vertical temperature gradients in the atmospheric boundary layer from near-surface temperature data is developed. The method is based on the statistical correlation existing between the ... -
The Contribution of Mesoscale Convective Weather Systems to the Warm-Season Precipitation in the United States
(American Meteorological Society, 1986)The contribution of precipitation from mesoscale convective weather systems to the warm-season (April?September) rainfall in the United States is evaluated. Both Mesoscale Convective Complexes (MCC's) and other large, ... -
Weibull Statistics of Wind Speed over the Ocean
(American Meteorological Society, 1986)The probability distribution of wind speed data over the world's oceans is studied using a two-parameter Weibull distribution. The parameters are estimated following a linearized least-squares approach. The seasonal and ... -

Comments on “A Model for Solar Irradiance and Radiance at the Bottom and Top of a Cloudless Atmosphere”
(American Meteorological Society, 1986)No abstract available. -
Comments on “Strategies for Assessing Skill and Significance of Screening Regression Models with Emphasis on Monte Carlo Techniques”
(American Meteorological Society, 1986)In a recent paper, Lanzante reviewed methods for estimating the skill and significance of screening regression models through the use of Monte Carlo simulations. The strategies reviewed have several limitations that were ... -
Cloud Cover Estimation Using Bispectral Satellite Measurements
(American Meteorological Society, 1986)An algorithm has been developed for cloud cover estimation using bispectral satellite measurements. Based on the distribution of pixels in albedo?brightness temperature space, a number of threshold values are applied to ... -

Characteristics of Supercooled Liquid Water in Clouds at Mountaintop Sites in the Colorado Rockies
(American Meteorological Society, 1986)Observations and measurements were made of supercooled liquid water in clouds which enveloped high elevation sites in the Colorado Rocky Mountains for the winters of 1980/81 through 1983/84. The observations showed that ... -
Atmospheric Mass Transport by Along-Valley Wind Systems in a Deep Colorado Valley
(American Meteorological Society, 1986)Hourly tethered-balloon wind soundings from the 650-m deep, narrow, Brush Creek Valley of Colorado are analyzed to determine the nocturnal atmospheric mass (or volume) budget of the valley. Under the assumption that the ... -
Urban Warming
(American Meteorological Society, 1986)Meteorological stations located in an urban environment in North America warmed between 1941 and 1980, compared to the countryside, at an average rate of about 0.12°C per decade. Secular trends of surface air temperature ... -
Mesoscale Wind Variability near Point Conception, California during Spring 1983
(American Meteorological Society, 1986)Wind variability in a mesoscale region near Point Conception, California is studied. The data base is derived from an array of near-surface meteorological recording stations yielding hourly winds during 51 days from 11 ... -
Reconstruction of Precipitation in Northeastern Nevada Using Tree Rings, 1600–1982
(American Meteorological Society, 1986)September?August annual precipitation in northeastern Nevada has been reconstructed for 1600?1982 using a single independent variable, an average of the White Horse Summit and Connors Pass tree-ring indices. The regression ... -
Southern Hemisphere Surface Air Temperature Variations: 1851–1984
(American Meteorological Society, 1986)A new compilation of monthly mean surface air temperature data for the Southern Hemisphere for 1851?1984 is presented based on land-based meteorological station data. Where possible, the station data used in the analysis ... -
An Extension of the Column Model Technique for Estimating Outgoing Longwave Irradiance: The Column Weighting Model
(American Meteorological Society, 1986)The procedure used by NOAA to estimate the outgoing longwave irradiance at the top of the atmosphere from an array of satellite window region measurements includes the averaging of the flux values inferred from the columns ...
