MEASUREMENT OF SNOW PARAMETERS BY RADAR
(American Meteorological Society, 1952)According to Rayleigh scattering theory for small spheres, back scattering is proportional to |K2Z where K is the dielectric factor and Z is the sum of the sixth powers of the diameter D. For small non-spherical particles ... -
THE DIURNAL VARIATION OF ATMOSPHERIC ELECTRICITY AS A METEOROLOGICAL-AEROLOGICAL PHENOMENON
(American Meteorological Society, 1952)This paper first gives a short survey of the modern view of atmospheric electricity. According to this, there exists in the atmosphere an electric-current system which generates from the thunderstorm activity and which is ... -
FLUCTUATIONS OF ATMOSPHERIC TEMPERATURE AS A MEASURE OF THE SCALE AND INTENSITY OF TURBULENCE NEAR THE EARTH'S SURFACE
(American Meteorological Society, 1952)This study summarizes certain preliminary observations on the structure of turbulence near the earth's surface. An array of sensitive bead thermistors is used to measure temperature or temperature-difference fluctuations ... -
AN OBSERVATIONAL STUDY OF THE UPPER WIND-CIRCULATION TROPICAL STORMS
(American Meteorological Society, 1952)All available rawin-reports taken within the circulation of tropical storms are combined to obtain a generalized pattern of the upper wind-circulation. The cyclonic circulation decreases rapidly with height, and by 45,000 ... -
ON THE LOW-LEVEL STRUCTURE OF THE TYPHOON EYE
(American Meteorological Society, 1952)Mean soundings are presented for the typhoon eye and storm circulation, based principally on dropsonde data taken by reconnaissance aircraft flying at the 700-millibar level. The vertical distribution of temperature and ... -
INFLUENCE OF LINE SHIFT AND ASYMMETRY OF SPECTRAL LINES ON ATMOSPHERHC HEAT-TRANSFER
(American Meteorological Society, 1952)The model of the stratosphere proposed by Strong and Plass assumed that the spectral lines had the Lorentz shape. Actually the center of the line shifts to a lower frequency by an amount proportional to the pressure, and ... -
A QUANTITATIVE METHOD FOR THE PREDICTION OF RAINFALL PATTERNS
(American Meteorological Society, 1952)Under certain assumptions, the vertical motion in the low and middle troposphere is directed upward in regions where the relative vorticity decreases downstream along the streamlines at 300 millibars, and inverse. Computations ... -
THREE-DIMENSIONAL DISTURBANCES IN A BAROCLINIC ZONAL CURRENT
(American Meteorological Society, 1952)In the first part of this paper, the partial differential equations governing the three-dimensional large-scale disturbances in a baroclinic zonal current are derived by applying a semi-Lagrangian coordinate system. These ... -
SEVERE TURBULENCE RESULTING FROM EXCESSIVE WIND-SHEAR IN TROPICAL CYCLONES
(American Meteorological Society, 1952)No Abstract Available -
NOTES ON THE MEAN JET-STREAM OVER AUSTRALIA
(American Meteorological Society, 1952)Further data on the distribution of the mean geostrophic west-wind over Australia are presented. Profiles of the 200-mb geostrophic west-wind for the southern and northern hemispheres are compared. The deduction is made ... -

THE WATER AND ENERGY BUDGETS OF THE THUNDERSTORM AND THEIR RELATION TO THUNDERSTORM DEVELOPMENT
(American Meteorological Society, 1952)A quantitative estimate, based upon data from the Thunderstorm Project, is made of the various water sources and sinks and the energy sources and sinks of an average thunderstorm cell. It is found that a large fraction of ... -
THE LATITUDE DEPENDENCE OF INTENSITY IN CYCLONES AND ANTICYCLONES
(American Meteorological Society, 1952)An enquiry is made into the way in which the mean intensities of cyclones and anticyclones vary with latitude. For middle latitudes a linear relation is shown to hold between the mean central pressure of cyclones, and of ... -
SOME REMARKS ON LETTAU'S NEW THEORIES OF THE ATMOSPHERIC SURFACE LAYER
(American Meteorological Society, 1952)No Abstract Available -
APPLICATION OF THE STATISTICAL THEORY OF TURBULENT DIFFUSION TO MICROMETEOROLOGY
(American Meteorological Society, 1952)Some elements of the statistical theory of turbulence are briefly reviewed from the viewpoint of their application to micrometeorology.Several relations concerning turbulent diffusion in a field of homogeneous and isotropic ... -
EVALUATION OF ADVECTIVE EDDY TERM OVER NEW ENGLAND FOR JANUARY 1945
(American Meteorological Society, 1952)No Abstract Available -
SYNOPTIC ASPECTS OF THE MONSOON CIRCULATION AND RAINFALL OVER INDO-PAKISTAN
(American Meteorological Society, 1952)The circulation and rainfall distribution over India during August 1949 were studied with a view toward determination of the degree of steadiness of monsoonal weather conditions. Not less than five different patterns of ... -
THE FEBRUARY MINIMUM IN HAWAIIAN RAINFALL AS A MANIFESTATION OF THE PRIMARY INDEX-CYCLE OF THE GENERAL CIRCULATION
(American Meteorological Society, 1952)The climatic minimum in rainfall observed in February at most stations in the Hawaiian Islands is ascribed to the expansion of the circumpolar westerly vortex of the mid-troposphere incident to the annual primary index-cycle. ... -
THE FLOW OF A LIQUID PAST A BARRIER IN A ROTATING SPHERICAL SHELL
(American Meteorological Society, 1952)The experiment reported in this paper was designed to study the effect of large mountain-barriers on zonal currents in the atmosphere. Obstacles of various sizes and shapes are moved zonally in a rotating spherical shell ... -
ATMOSPHERIC SALT PARTICLES AND RAINDROPS
(American Meteorological Society, 1952)Marshall and Palmer (1948) have shown that, for rains of a given intensity, there is a definite distribution curve of number of raindrops of a particular range of diameter. The writer has indicated here that the chlorinity ...
