Temperature Corrections for the VIZ and Vaisala Radiosondes
(American Meteorological Society, 1995)The National Weather Service VIZ radiosonde and the Vaisala RS-80 radiosondes are used worldwide to obtain upper-air measurements of atmospheric temperature and moisture. The temperature measured by each sensor is not equal ... -
Automated Classification Scheme for Wind Fields
(American Meteorological Society, 1995)In earlier works of several authors, wind fields or flow patterns were grouped by means of trajectory calculations or by use of a principal component analysis. A new automated classification method is proposed that makes ... -
Modeling and Parameterization of Near-Source Diffusion in Weak Winds
(American Meteorological Society, 1995)A critical assessment is made of several different approaches that can be used for modeling near-source diffusion in weak winds, including the calm condition. For the convective boundary layer, the statistical theory ... -
Accuracy Analysis of Rubsonde-GPS Wind Sounding System
(American Meteorological Society, 1995)The results of program of estimate the limiting accuracy of atmospheric wind profiles obtained by tracking a new balloon, the Rubsonde, with the Global Positioning System (GPS) are presented. In the first part, the authors ... -
A New Look at the Israeli Cloud Seeding Experiments
(American Meteorological Society, 1995)Two statistical experiments, carried out in Israel, appeared for a time to have provided a unique demonstration of the ability of cloud seeding to increase rainfall. In this paper the authors examine the possibility that ... -
Improved Detection of Optically Thin Cirrus Clouds in Nighttime Multispectral Meteorological Satellite Imagery Using Total Integrated Water Vapor Information
(American Meteorological Society, 1995)The accurate identification of optically thin cirrus clouds in global meteorological satellite imagery by automated cloud analysis algorithms is critical to environmental remote sensing studies, such as those related to ... -
An Intercomparison of Gauge Observations and Satellite Estimates of Monthly Precipitation
(American Meteorological Society, 1995)In order to further our quantitative understanding of the advantages and the shortcomings of the various sources of data used to represent climatic-scale precipitation, monthly gauge observations and satellite estimates ... -
Tornado Detection Based on Seismic Signal
(American Meteorological Society, 1995)At the present time the only generally accepted method for detecting when a tornado is on the ground is human observation. Based on theoretical considerations combined with eyewitness testimony, there is strong reason to ... -
Thermal Remote Sensing of Surface Soil Water Content with Partial Vegetation Cover for Incorporation into Climate Models
(American Meteorological Society, 1995)This study outlines a method for the estimation of regional patterns of surface moisture availability (M0) and fractional vegetation (Fr) in the presence of spatially variable vegetation cover. The method requires relating ... -
A Comparison of Seeded and Nonseeded Orographic Cloud Simulations with an Explicit Cloud Model
(American Meteorological Society, 1995)Ice initiation by specific cloud seeding aerosols, quantified in laboratory studies, has been formulated for use in mesoscale numerical cloud models. This detailed approach, which explicitly represents artificial ice nuclei ... -
A Review of Procedures for Updating Air Quality Modeling Techniques for Regulatory Programs
(American Meteorological Society, 1995)Air quality models are a key component in determining pollution control requirements. To ensure that the best techniques are used, modeling guidance must be flexible and include better techniques as they become available. ... -
An Estimation of the Bulk Transfer Coefficients for a Bare Soil Surface Using a Linear Model
(American Meteorological Society, 1995)A linear heat budget model is developed to estimate the daytime means of the bulk transfer coefficients for heat and evaporation efficiency using the daily variation of observational data. The daily variation of shortwave ... -
Surface Measurements of Solar Irradiance: A Study of the Spatial Correlation between Simultaneous Measurements at Separated Sites
(American Meteorological Society, 1995)Pyranometers have been used for many years to measure broadband surface incoming solar irradiance, data that is necessary for surface energy budget, cloud forcing, and satellite validation research. Because such measurements ... -
Multiparameter Radar Study of Rainfall: Potential Application to Area Time Integral Studies
(American Meteorological Society, 1994)Multiparameter radar measure one or more additional parameters in addition to the conventional reflectivity factor. The combination of radar observations from a multiparameter radar is used to study the time evolution of ... -
