THE COLLISION EFFICIENCY OF CLOUD DROPS OF EQUAL SIZE
(American Meteorological Society, 1957)An investigation by modeling techniques has been made of the collision between cloud drops of equal size in the diameter range from 11 to 22 microns. It was found that such drops will collide with an initial vertical ... -
COMMENTS ON "TURBULENT DISPERSION OF DYNAMIC PARTICLES"
(American Meteorological Society, 1957)No Abstract Available. -
RELATIVE ATMOSPHERIC DIFFUSION OF SMOKE PUFFS
(American Meteorological Society, 1957)The spreading of smoke puffs in the atmosphere should be governed by the laws of relative diffusion that have been advanced by Brier and by Batchelor, and not (contrary to what has been previously assumed) by Taylor's ... -

SOME KINEMATIC ASPECTS OF FRONTAL ZONES
(American Meteorological Society, 1957)It is possible that the technique of wind analysis, developed long ago by Sandstrom and V. Bjerknes, may supplement the standard isobaric and frontal analysis of surface weather maps. A first approximation to a theory ... -
SPACE AND TIE CORRELATIONS IN WIND VELOCITY

THE DISTRIBUTION OF SOLAR RADIATION THROUGHOUT SOUTHERN AFRICA
(American Meteorological Society, 1957)Since about 1950, considerable emphasis has been placed upon the registration of solar radiation in Africa by a number of the meteorological services of the territories on the continent. It is now considered that sufficient ... -
EVAPORATION, AND MOISTURE AND HEAT FIELDS IN THE SOIL
(American Meteorological Society, 1957)Recent developments in the study of moisture and heat fields in the soil are applied to the problem of evaporation from bare soil surfaces. Most of the analysis is confined to steady conditions, but it definitely suggests ... -
COMPARATIVE STUDIES OF RELATIVE VORTICITIES COMPUTED FROM GEOSTROPHIC AND OBSERVED WINDS
(American Meteorological Society, 1957)Fixed networks of rawinsonde stations were used to compute geostrophic relative vorticity from reported heights and observed relative vorticity from components of reported winds at 500 mb. The geostrophic vorticity was ... -
A PRELIMINARY REPORT ON THE DESIGN OF A COMPUTER FOR MICROMETEOROLOGY
(American Meteorological Society, 1957)Since all micrometeorological parameters must be uniquely determined by the macrometeorological parameters and the characteristics of the underlying surface, it should be possible to predict the former from a knowledge of ... -
A POSSIBLE SUNSPOT INFLUENCE ON THE GENERAL CIRCULATION
(American Meteorological Society, 1957)No Abstract Available. -
THE NON-EQUILIBRIUM ELECTRIFICATION OF RAINDROPS BY THE ASSOCIATION OF CHARGED CLOUD DROPLETS
(American Meteorological Society, 1957)Whenever the number of collisions experienced by raindrops growing by coalescence with cloud droplets is limited either by a finite distance of fall or by the drop size, then the accumulated electrical charge is similarly ... -
HEMISPHERIC NUMERICAL FORECASTING WITH THE BAROTROPIC MODEL, AND SOME REMARKS ON BOUNDARY-CONDITION ERROR
(American Meteorological Society, 1957)After further experiments with a pilot case reported earlier, the results are summarized for a selected ten-day series of predictions obtained over the northern hemisphere by conventional numerical methods with the barotropic ... -
A GRAPHICALLY INTEGRABLE PREDICTION MODEL INCORPORATING OROGRAPHIC INFLUENCES
(American Meteorological Society, 1957)An attempt to incorporate the effect of sloping terrain in a two-level model is presented. The resulting prediction equations may be integrated by graphical techniques. To derive the equations, it is necessary to prescribe ... -
A CORRECTED MIXING-LENGTH THEORY OF TURBULENT DIFFUSION
(American Meteorological Society, 1957)The results of the conventional mixing-length theory disagree with those of the statistical theory of turbulence, and must be rejected also on common-sense grounds since they imply the existence of infinite velocities. ... -
ELECTRIC ACTIVITY ASSOCIATED WITH THE BLACKWELL-UDALL TORNADO
(American Meteorological Society, 1957)No Abstract Available. -
