50-MILLIBAR PATTERNS AND THEIR RELATIONSHIP TO TROPOSPHERIC CHANGES
(American Meteorological Society, 1956)Data from three recent winters are utilized to study the large changes in the temperature and flow fields at 50 mb. It is reasoned that the major changes in this region arise from the development of an unstable flow pattern ... -
METEOROLOGICAL APPLICATIONS OF CONSTANT-PRESSURE BALLOON TRAJECTORIES
(American Meteorological Society, 1956)The areal coverage to be expected from 300-millibar constant-pressure balloons (CPB) is examined for various numbers of releases per day from various stations. The meteorological variables which can be measured are discussed. ... -
THE SEMI-ANNUAL PRESSURE OSCILLATION, ITS CAUSE AND EFFECTS
(American Meteorological Society, 1956)No Abstract Available -
PARTICULATE COUNTS IN NATURAL CLOUDS AND FOGS
(American Meteorological Society, 1956)Measurements of droplet count have been made in fogs, natural clouds, and laboratory clouds. All droplets larger than 0.75-micron radius that were contained in a small volume (approximately 1 cubic centimeter) of the cloud ... -
AN APPROXIMATE ANALYSIS OF THE SOLAR REFLECTANCE AND TRANSMITTANCE OF A SNOW COVER
(American Meteorological Society, 1956)The transmittance and reflectance of a snow cover has been analyzed by use of the model of a diffusing medium introduced by Schuster. The general case of a slab of finite thickness, irradiated from both sides, is solved ... -
THE TEMPERATURE DISTRIBUTION NEAR A COLD SURFACE
(American Meteorological Society, 1956)Theoretical considerations suggest that the temperature distribution within a meter of a cold surface may be partially stratified as a result of radiative and turbulent processes. Even though stratification would be of ... -
COMMENTS ON "A GENERAL SURVEY OF FACTORS INFLUENCING DEVELOPMENT AT SEA LEVEL"
(American Meteorological Society, 1956)No Abstract Available -
CRITERIA FOR THE OCCURRENCE OF AN ECCENTRIC CIRCUM-POLAR VORTEX IN THE ATMOSPHERE INFERRED FROM MODEL EXPERIMENTS

A TEST OF NUMERICAL PREDICTION METHODS BASED ON THE BAROTROPIC AND TWO-PARAMETER BAROCLINIC MODELS
(American Meteorological Society, 1956)A two-parameter baroclinic model for vertically integrated flow is derived under the assumption of an isogonal geostrophic wind shear, and constitutes a generalization of the theory of equivalent baroclinic flow. The ... -

THE RELATION BETWEEN RAINFALL AND METEOR SHOWERS
(American Meteorological Society, 1956)Examination of rainfall figures for a large number of stations shows that there is a tendency for more rain to fall on certain calendar dates than on others. There is a close correspondence between the dates of the rainfall ... -
KINETIC-ENERGY SPECTRUM OF MERIDIONAL MOTION IN THE MID-TROPOSPHERE
(American Meteorological Society, 1956)A study is made of the daily kinetic-energy spectra of meridional motions at 500 millibars at latitude 45°N for a three-months winter period. A pronounced characteristic of these spectra is the occurrence of a double ... -
A SELECTIVE ANALYSIS OF THE SCALE OF ATMOSPHERIC TURBULENCE
(American Meteorological Society, 1956)A preliminary investigation of the scale problem in atmospheric turbulence has been carried out. An analytic filter of limited resolving power is applied to simultaneous data from four heated-thermocouple anemometers spaced ... -
ENERGY-RELEASING PROCESSES AND STABILITY OF THERMALLY DRIVEN MOTIONS IN A ROTATING FLUID
(American Meteorological Society, 1956)The effects of the various physical factors on the motions produced by differential heating in a rotating fluid are examined by solving the simultaneous hydrodynamic and thermodynamic equations. It is shown that both the ... -
ON THE MAGNITUDE OF DIVERGENCE AND VORTICITY
(American Meteorological Society, 1956)No Abstract Available -
THE INFLUENCE OF SNOW COVER ON LOCAL CLIMATE IN GREENLAND
(American Meteorological Society, 1956)Study of thermal storage in the local environment (landscape and climatologic air) provides an approach to an understanding of surface-created local climates, such as those in snow-covered regions. Such a local climate, ... -
LONG WAVES IN A TWO-FLUID SYSTEM
(American Meteorological Society, 1956)The differential equations governing the unsteady motion of a system of two superimposed liquids are integrated by use of the method of characteristics. The solution differs significantly from that obtained by assuming a ... -
A THREE-PARAMETER BAROCLINIC NUMERICAL-PREDICTION MODEL
(American Meteorological Society, 1956)From the premise that the modelling approximation for an integrated numerical-prediction model is given by a constraint on the stability factor in the first law of thermodynamics for adiabatic flow, a three-parameter ...
