DEPENDENCE OF THE FORMS OF NATURAL SNOW CRYSTALS ON METEOROLOGICAL CONDITIONS
(American Meteorological Society, 1954)Observations were made on the crystal structure of natural snow during a snowfall and related to the meteorological data obtainable for the period of observation. A dependence of crystal type on temperature, in reasonable ... -
ENERGY TRANSFER BY INFRARED BANDS
(American Meteorological Society, 1954)The energy transfer between air layers, and that between an air layer and black surface, are examined for a schematic rotation-vibration band of a gas whose mixing ratio decreases with height. It is found, in general, that ... -
FURTHER COMMENTS ON VISIBILITY AND LIQUID CONTENT IN CLOUD
(American Meteorological Society, 1954)No Abstract Available -
PLANETARY WAVES IN THE ATMOSPHERE
(American Meteorological Society, 1954)A numerical method is presented for solving the non-linear barotropic vorticity equation in spherical coordinates. It is shown that, when the stream function is expressed as a sum of surface spherical harmonics, the ... -
RADAR EVIDENCE OF A GENERATING LEVEL FOR SNOW
(American Meteorological Society, 1954)Vertical-section radar observations of precipitation in the winter of 1951?1952 have been related to upper-air data. On three of the 22 days, there was very little signal and practically no pattern observed. It is possible ... -
ERRORS INHERENT IN THE RADAR MEASUREMENT OF RAINFALL AT ATTENUATING WAVELENGTHS
(American Meteorological Society, 1954)An equation for the rate of rainfall at a given range from the radar is derived. This is expressed in terms of the power level of the received signal (corrected for attenuation by intervening cloud and atmospheric gases) ... -
ASPECTS OF THE CIRCULATION OF THE SOUTHERN HEMISPHERE
(American Meteorological Society, 1954)An evaluation is made of the synoptic features and characteristic pressure patterns of the Southern Hemisphere as they relate to the seasonal circulations. Examples of both strong and weak polar outbreaks are presented, ... -

ON FLUCTUATIONS OF THE ATMOSPHERIC CIRCULATION IN THE VICINITY OF SOUTH AMERICA, AND THEIR RELATION TO SUNSPOTS
(American Meteorological Society, 1953)The longitudinal section of pressure distribution over a given hemisphere shows minima near the equator and at about latitude 60 deg, and has maxima at about latitude 30 deg and near the pole. A trigonometric equation with ... -
PREDICTION OF WET PERIODS IN EGYPT FOUR TO SIX DAYS IN ADVANCE
(American Meteorological Society, 1953)An attempt is made to predict the occurrence of wet periods in the Middle East 4 to 6 days in advance. Such a forecast is of great value for cotton cultivation in Egypt during the cold season (December to March). Generally, ... -

SOME POSSIBLE APPLICATIONS OF MOMENTUM-TRANSPORT THEORY
(American Meteorological Society, 1954)The accumulation of relative angular momentum due to transport into zonal ring segments between selected longitudes is studied with the help of five-day mean 700-mb charts. Latitudinal displacement and intensity tendencies ... -
ON THE ANNUAL HEAT BALANCE OF THE NORTHERN HEMISPHERE
(American Meteorological Society, 1954)The increased knowledge of atmospheric radiation during the last twenty years has made it desirable to re-compute the heat balance of the northern hemisphere. Insofar as possible the computations are based on observational ... -
HOMOGENEOUS NUCLEATION OF SUPERCOOLED WATER DROPS
(American Meteorological Society, 1953)The experimentally observed crystallization of supercooled water near ?40C is examined in terms of the theory of homogeneous nucleation. The thermodynamic and molecular-kinetic nature, of the nucleation process is outlined ... -

A STUDY OF VERTICAL VELOCITIES IN THE VICINITY OF JET STREAMS
(American Meteorological Society, 1953)Three-hour average vertical velocity values are computed at the 500-and 300-mb levels under the assumption of adiabatic motion by the ?isobaric? technique. The patterns of the isolines of vertical velocity (isanabats) are ... -

COMMENTS ON THE IMPULSIVE GENERATION OF CERTAIN CHANGES IN THE TROPOSPHERIC CIRCULATION"
(American Meteorological Society, 1953)No Abstract Available -
RAINDROP SIZE-DISTRIBUTION IN HAWAIIAN RAINS
(American Meteorological Society, 1953)A brief survey of the major techniques of raindrop size-sampling is given. The filter-paper technique, finally adopted for use in this study, adapts itself admirably to the sampling of Hawaiian orographic rains. The change ... -
STRUCTURE OF ATMOSPHERIC TURBULENCE
(American Meteorological Society, 1953)Experimental data on the energy spectra, correlation coefficients and energy isotropy of atmospheric turbulence at low elevations are presented. It is shown that the very simple formulas derived with the aid of Kolmogoroff's ...
