THE GROWTH OF SEA-SALT PARTICLES BY CONDENSATION OF ATMOSPHERIC WATER VAPOR
(American Meteorological Society, 1954)Measurements of the rate of growth of sea-salt particles have been made when the particle is shifted from an environment of dry air to one of relative humidity between 80 and 100 per cent. For particles ranging in mass ... -
NOTES ON THE TRANSFORMATION OF MECHANICAL ENERGY FROM AND TO EDDYING MOTION
(American Meteorological Society, 1954)The equations of mechanical energy of total, mean and eddying motions are derived and discussed. It is shown that, in general, no term of these equations can directly be interpreted as representing the rate of transformation ... -
AN ABRIDGED METHOD FOR COMPUTING DAYTIME AND NIGHTTIME AVERAGES OF SOME METEOROLOGICAL ELEMENTS
(American Meteorological Society, 1954)A method is described for calculating mean values of some meteorological elements for the periods sunrise to sunset, and sunset to sunrise, respectively. The method is simple to apply and requires relatively few data, ... -
ON THE USE OF CONSTANT-LEVEL BALLOONS TO MEASURE HORIZONTAL MOTIONS IN THE ATMOSPHERE
(American Meteorological Society, 1954)In the course of government-sponsored work in the development of the constant-level balloon, the writers supervised many constant-level balloon flights on the standard meteorological surface of 300 millibars. The tracks ... -
THE USE OF CORRELATION FIELDS IN RELATING PRECIPITATION TO CIRCULATION
(American Meteorological Society, 1954)The physical meaning of a correlation-field pattern is explored, and such patterns are shown to be analogous to composite patterns. Correlation fields are used to investigate the relationship of precipitation to mean ... -
A PROPOSED MECHANISM FOR THE DEVELOPMENT OF THE EYE OF A HURRICANE
(American Meteorological Society, 1954)An attempt is made to explain the process of the development and growth of the eye of a hurricane from the small immature stage to the large mature stage. The assumption is made that a hurricane starts as a simple vortex ... -
STUDIES OF ALASKAN ICE-FOG PARTICLES
(American Meteorological Society, 1954)During the 1952?1953 winter, studies were made at Eielson Air Force Base, Alaska, of ice fog and other low-temperature aerosol phenomena. The particulate material, collected by settling onto glass slides at temperatures ... -
REGIONS OF VALIDITY OF VARIOUS ABSORPTION-COEFFICIENT APPROXIMATIONS
(American Meteorological Society, 1954)No Abstract Available -
A NOTE ON THE APPLICATION OF THE HYDROSTATIC EQUATION TO ATMOSPHERIC STATISTICS
(American Meteorological Society, 1954)No Abstract Available -
THE OCCURRENCE OF CRITICAL FLOW AND HYDRAULIC JUMPS IN A MULTI-LAYERED FLUID SYSTEM
(American Meteorological Society, 1954)With use of the speed of long waves of infinitesimal amplitude as the criterion for critical flow, general expressions are obtained for critical conditions in a fluid system of n layers, where velocity as well as density ... -
INITIATION OF SHOWERS BY SNOW
(American Meteorological Society, 1954)Examination of radar records shows that snow trails frequently occur around the tops of showers. Evidence has been sought that showers are occasionally initiated by the seeding of supercooled cumulus clouds by snow. Certain ... -
ELECTRIC-FIELD REGENERATION IN THUNDERSTORMS
(American Meteorological Society, 1954)A season's.record of the electric-field intensity measured on the earth during active thunderstorms is evaluated. The records show that two basic types of storms exist. The most common, or positive, type of active storm ... -
THE HIGH TROPOSPHERE OF THE TROPICS: A PROBLEM FOR THE INTERNATIONAL GEOPHYSICAL YEAR
(American Meteorological Society, 1954)No Abstract Available -
AN INFRARED DETECTOR FOR MEASUREMENT OF THE BACK RADIATION FROM THE SKY
(American Meteorological Society, 1954)A long-wave radiometer is described in considerable detail. Physical and transmission characteristics of the hemispherical ?windows? are presented, and calibration and use of the instrument are discussed. The results of a ... -
AN APPROXIMATE METHOD OF DIVERGENCE MEASUREMENT
(American Meteorological Society, 1954)With the vorticity equation for horizontal motion as a beginning, and with the aid of several assumptions, the equation ?H·? = ?T·?H In ? is derived, giving the horizontal divergence as the product of (?T) the vector ... -
A THEORY OF SNOW-CRYSTAL HABIT AND GROWTH
(American Meteorological Society, 1954)Strong evidence, available from the experiments of Nakaya and his co-workers and bolstered by an analogue experiment, supports the argument that type of snow-crystal growth is determined principally by the excess of the ... -
A LABORATORY INVESTIGATION OF COLLISION EFFICIENCIES, COALESCENCE AND ELECTRICAL CHARGING SIMULATED CLOUD DROPLETS
(American Meteorological Society, 1954)A laboratory experiment is described in which liquid drops are formed in a viscous medium to simulate cloud droplets in air by equating the Reynolds number for the experiment to that of the atmospheric case. Certain ... -

(American Meteorological Society, 1954)No Abstract Available -
ON THE ASYMMETRY OF THE MIDDLE-LATITUDE CIRCUMPOLAR CURRENT
(American Meteorological Society, 1954)Evidence is presented that the circumpolar current of temperature latitudes often is not symmetric about the earth's axis of rotation. This asymmetry, which varies with time, is frequently so large that the ?zonal index? ...
