DROPLET-ELECTRIFICATION PROCESSES AND COAGULATION IN STABLE AND UNSTABLE CLOUDS
(American Meteorological Society, 1955)The fundamental electromechanics of droplet electrification and coagulation within stable and unstable clouds is investigated. The analysis shows that atmospheric ions formed by cosmic rays or other means normally diffuse ... -

ANGULAR MOMENTUM AS A PARAMETER IN THE INVESTIGATION OF CYCLONE-SCALE CIRCULATIONS
(American Meteorological Society, 1955)Angular momentum relative to a fixed vertical axis is used as a measure of rotational flow on the scale of cyclones and anticyclones. An exact equation derived by Starr for the time rate of change of this momentum is ... -
ON THE FORECASTING POSSIBILITIES OF EMPIRICAL INFLUENCE FUNCTIONS
(American Meteorological Society, 1955)The possibilities of using empirically derived influence functions for forecasting the upper-air contour-height distribution are explored. Such empirical influence functions are derived for an irregular three-dimensional ... -
TURBULENCE AND SHEARING STRESSES MEASURED OVER THE NORTH ATLANTIC OCEAN BY AN AIRPLANE-ACCELERATION TECHNIQUE
(American Meteorological Society, 1955)A method of measuring the horizontal and vertical turbulent components of the wind has been developed to meet the need for these measurements over the open ocean. An anemometer, a vertical accelerometer, and a gyroscope ... -
INTENSIFICATION OF PRECIPITATION BY DIFFERENTIAL ADVECTION
(American Meteorological Society, 1955)The effect of vertical instability on the intensity of precipitation is illustrated by a theoretical example. This example and others from the literature lead to the hypothesis that instability produced by a process such ... -
A CASE STUDY OF HURRICANE FORMATION
(American Meteorological Society, 1955)The development of storm Alice of 1953 in the Gulf of Mexico is studied by means of successive changes in the thickness patterns between four standard isobaric surfaces. The manner in which the patterns change indicates ... -
DETERMINATION OF HIGH-ALTITUDE WINDS AND TEMPERATURES IN THE ROCKY MOUNTAIN AREA BY ACOUSTIC SOUNDINGS, OCTOBER 1951
(American Meteorological Society, 1955)An attempt was made to determine upper-atmosphere winds and temperatures to 100 kilometers by acoustic soundings during the early part of October 1951. At the first inversion near 50 km, light and variable winds with ... -
ON ICE-CRYSTAL NUCLEI AND OTHER SUBSTANCES FOUND IN SNOW CRYSTALS
(American Meteorological Society, 1955)Ice-crystal nuclei and other substances found in snow crystals collected in Japan were observed with an electron microscope and identified by means of their electron diffraction-patterns. Among the nuclei observed, clay ... -
HOMOGENEOUS NUCLEATION IN SUPERCOOLED WATER
(American Meteorological Society, 1955)No Abstract Available -

A NEW ASPECT OF COALESCENCE THEORY
(American Meteorological Society, 1955)The process of growth by coalescence is examined from the viewpoint of a discrete rather than a continuous accretion process. It is concluded that, for drops beginning growth at twice the volume of their neighbors, random ... -

NOTE ON HORIZONTAL DIFFUSIVITY FOR LARGE-SCALE TROPOSPHERIC CURRENTS
(American Meteorological Society, 1955)No Abstract Available -
SPECIFICATION OF TEMPERATURE AND PRECIPITATION IN TERMS OF CIRCULATION PATTERNS
(American Meteorological Society, 1955)High-speed calculation techniques using Whirlwind I, the digital computer at the Massachusetts Institute of Technology, make practical the use of an objective approach to the classification of climatic data based on the ... -
FURTHER REMARKS ON THE CORRELATION OF DENSITY OF NEW SNOW WITH 700-MILLIBAR TEMPERATURE
(American Meteorological Society, 1955)No Abstract Available -
NOTES ON THE TRANSFORMATION OF MECHANICAL ENERGY FROM AND TO EDDYING MOTION
(American Meteorological Society, 1955)No Abstract Available -
A THREE-DIMENSIONAL STUDY OF THE HORIZONTAL VELOCITY DIVERGENCE
(American Meteorological Society, 1955)A three-dimensional picture of the horizontal velocity divergence is constructed at seven times, at twelve-hour intervals, with use of observed winds as a basis for divergence computations. No level of non-divergence is ... -
THE NATURE AND DETECTABILITY OF CLOUDS AND PRECIPITATION AS DETERMINED BY 1.25-CENTIMETER RADAR
(American Meteorological Society, 1955)A survey is made of the clouds and precipitation detected at a wavelength of 1.25 centimeters. The frequencies of various cloud types and their typical echo characteristics are presented. Within 89 periods during which ... -
RADAR ANALYSIS OF PRECIPITATION STREAMERS OBSERVED 25 FEBRUARY 1954
(American Meteorological Society, 1955)A radar study of the streamers of 25 February 1954 at Cambridge, Mass., indicates that horizontal bands of rain are produced by the action of wind shear on the precipitation particles. It is suggested that a ?generating ...
