On Certain Truncation Errors Associated with Spherical Coordinates
(American Meteorological Society, 1970)Excessive errors are committed in grids, in which mesh-lengths in the longitudinal direction are preserved in polar regions, if the hydrodynamic equations written in spherical coordinates are directly transformed into ... -
Parameterization of Macroscale Transient Heat Transport for Use in a Mean-Motion Model of the General Circulation
(American Meteorological Society, 1970)Recent work on mean-motion models of the general circulation has led to renewed interest in the parameterization (i.e., expression in terms of model-generated average variables) of the horizontal flux of heat in the ... -
Experiments with a Regional Fine-Mesh Prediction Model
(American Meteorological Society, 1970)Twelve and 24-hr 500-mb forecasts have been made using a hemispheric dependent, limited-area, fine-mesh prediction model. The model is barotropic and makes use of the primitive equations. Boundary conditions are obtained ... -

Meteorological Application of Satellite Window Radiation
(American Meteorological Society, 1970)Some of the TIROS satellites measured several bands of radiation from which characteristics of the atmosphere can be inferred. In this study, the 8?12? band of window radiation data from TIROS II, III and IV were used in ... -
Statistical Characteristics of Subtropical jet-Stream Features in Terms of MRIR Observations from Nimbus II
(American Meteorological Society, 1970)A sample of 60 individual cases of southwesterly jet-stream maxima located over the continental United States during the Nimbus II period is studied in relation to the MRIR characteristics surrounding the jet. The analysis ... -
A Study of Cloud Distributions using Reflected Radiance Measurements from the ATS Satellites
(American Meteorological Society, 1970)Reflected radiance measurements from the multicolor spin-scan cloud camera on Applications Technology Satellite III are used to determine the percentages of selected areas of the earth that are cloud-free. The areas chosen ... -
Integration of Radar and Raingage Data for Improved Rainfall Measurement
(American Meteorological Society, 1970)Oklahoma thunderstorm data were used to determine how the estimation of area rainfall by radar can be improved by using one or several raingages. The radar data were collected between 1964 and 1968 with the WSR-57 radar ... -
Elevation and Spatial Variation Effects of Wintertime Orographic Cloud Seeding
(American Meteorological Society, 1970)This study is concerned with the elevation and spatial variation effects of wintertime orographic cloud seeding over an area encompassing Fremont, Hoosier and Vail mountain passes in the central Colorado mountains during ... -
Lead Measurement in Urban Air As It Relates to Weather Modification
(American Meteorological Society, 1970)Results from measurements made to study the behavior of lead aerosols in Denver urban air as latent ice nuclei are discussed. In the study, use was made of three independent measuring systems. These were: 1) an NCAR ... -
The Use of Jet Aircraft Engines to Dissipate Warm Fog
(American Meteorological Society, 1970)This paper describes a pilot study carded out to determine the feasibility of using the heat and mixing properties of jet engine exhaust to evaporate fog from an aircraft runway. It was found that visibilities can be raised ... -
Some Numerical Experiments for Warm Fog Clearing by Seeding with Hygroscopic Nuclei
(American Meteorological Society, 1970)The effectiveness of warm fog clearing by seeding with hygroscopic nuclei was studied numerically. A parcel of air with a known distribution of fog droplets was assumed to be seeded with hygroscopic nuclei. While new drops ... -
Mid-Tropospheric Cyclones of the Southwest Monsoon
(American Meteorological Society, 1970)Mid-tropospheric cyclones are an important part of the tropical general circulation of the summer season. These are synoptic-scale disturbances which appear in the daily and monthly mean circulation maps with greatest ... -
Interaction of Binary Tropical Cyclones of the Western North Pacific Ocean
(American Meteorological Society, 1970)Fifteen years of typhoon data (1953?67) were evaluated to determine the general character of the ?Fuji-whara effect? with respect to the separation distance between two interacting tropical cyclones. The results show that ... -
Mesoscale Weather Systems within an Occlusion
(American Meteorological Society, 1970)Precipitation systems within a mature extratropical cyclone are related to the mesoscale thermal and circulation fields aloft using data from Project Stormy Spring conducted by the Air Force Cambridge Research Laboratories. ... -
The Energy Budget Over the Florida Peninsula When a Convective Regime Dominates
(American Meteorological Society, 1970)In order to assess the role played by convective processes in the vertical transfer of energy, the mean structure and energy budget over the Florida Peninsula have been studied, when the convective scale is the dominant ...
