AN INVESTIGATION OF CERTAIN SHORT-PERIOD ATMOSPHERIC MICRO-OSCILLATIONS
(American Meteorological Society, 1953)An equation is developed, to show the magnitude of pressure change required to produce a given amplitude for a given period on the galvanometric record of the Macelwane electromagnetic microbarograph. The simultaneous ... -
PHYSICAL PROPERTIES OF CUMULUS CLOUDS
(American Meteorological Society, 1953)Measurements of droplet size and visibility have been made at different levels above the base of all types of cumulus clouds. The evaluation of these data permits calculations of corresponding values of water content and ... -
FORECASTING THE SPEED OF MOVEMENT OF SELECTED CYCLONES ALONG UPPER-AIR STEERING CHANNELS
(American Meteorological Society, 1953)Following the selection of upper-air steering channels on the basis of the height of the ?closed? circulation, an objective technique is developed for forecasting the 24- and 30-hour displacements of surface ?lows.? Data ... -
THE DYNAMICS OF A VORTEX EMBEDDED IN A CONSTANT ZONAL CURRENT
(American Meteorological Society, 1953)The condition that the absolute vorticity be conserved is applied to the model of a symmetric vortex embedded in a constant zonal current. It is shown that the radial variation of the rotational component of the wind must ... -
THE RADIATIONAL TEMPERATURE CHANGES OVER THE EASTERN NORTH PACIFIC OCEAN IN JULY 1949
(American Meteorological Society, 1953)The net gain or loss of energy at 700 millibars over the eastern North Pacific Ocean due to the absorption and emission of radiation by water vapor was computed for nine days during a period when the subtropical anticyclone ... -
A MECHANISM FOR CONVECTION OVER THE OCEAN
(American Meteorological Society, 1953)The cumuli which form over the ocean near Puerto Rico cannot be the result of ?thermals.? A theory is evolved, based on the oscillation of the boundary between the well-mixed layer near the ocean and the cloud layer. The ... -
STEADY MOTION AROUND A SYMMETRICAL OBSTACLE MOVING ALONG THE AXIS OF A ROTATING LIQUID
(American Meteorological Society, 1953)An investigation by G. I. Taylor, of the steady motion of an obstacle along the axis of a rotating fluid, is extended in this paper. It is shown that Taylor's particular solution is just one of an infinity of functions ... -
METHOD OF NUMERICAL FORECASTING BY JUXTAPOSITION OF ONE-DIMENSIONAL SOLUTIONS, AND ITS APPLICATION TO THE EQUIVALENT BAROTROPIC MODEL
(American Meteorological Society, 1953)By juxtaposition of a series of one-dimensional solutions at adjacent latitudes, numerical forecasts may easily and inexpensively be incorporated into forecasting routine. Forecasts for 140 degrees of longitude, for the ... -
A THEORY OF THE TEMPORAL AND LATITUDINAL DISTRIBUTION OF TEMPERATURE
(American Meteorological Society, 1953)An attempt is made to explain the observed distribution of mean temperature near the earth's surface over latitude and through the year in terms of insolation, radiative processes, and large-scale atmospheric eddy conduction ... -
CLOUD VISIBILITY, RADAR REFLECTIVITY, AND DROP-SIZE DISTRIBUTION
(American Meteorological Society, 1953)The coefficient C in Trabert's visibility equation, V = (C?r?)/W, where r? is linear mean radius, ? density, and W is liquid-water content, is shown to be a function of the breadth of the drop-size distribution but has ... -
REMARKS ON "ATMOSPHERIC SALT PARTICLES AND RAINDROPS"
(American Meteorological Society, 1953)No Abstract Available -
POLARIZATION OF LIGHT FROM ILLUMINATED AREAS IN A CEILOMETER BEAM DURING RAIN
(American Meteorological Society, 1953)The observed polarization of the light emitted from certain illuminated areas in a ceilometer beam during rain is explained as due to the polarization of light rays by reflection and refraction in passing through the ... -
PRELIMINARY REPORT ON SEA SALT AS AN ICE NUCLEUS

SEASONAL VARIATIONS OF THE ANTARCTIC TROPOPAUSE
(American Meteorological Society, 1953)Computations of radiative cooling are made, and the conclusion is reached that the rate of cooling in the antarctic atmosphere is more than sufficient for the observed minimum temperatures to be attained in the lower ... -
TILTED-TROUGH MODEL AS AN INTERACTION BETWEEN LOW- AND HIGH-LATITUDE DISTURBANCES
(American Meteorological Society, 1953)No Abstract Available -
REGIONS OF VALIDITY OF VARIOUS ABSORPTION-COEFFICIENT APPROXIMATIONS
(American Meteorological Society, 1953)Elsasser's integral for the absorption by a periodic line pattern is evaluated and used to examine the validity of various approximations concerning the absorption coefficient. It is found that composite absorption curves, ... -
OBSERVATION OF NON-RAYLEIGH SCATTERING IN THE SPECTRUM OF THE DAY SKY IN THE REGION 0.56 TO 2.2 MICRONS
(American Meteorological Society, 1953)Spectral records of the day skylight from 0.56 to 2.2µ were obtained at 5415- and 2200-ft stations for the morning sun along the solar almucantar with a lead-sulfide cell and glass-prism spectrometer. Scattering intensities ... -
NUMERICAL INTEGRATION OF THE QUASI-GEOSTROPHIC EQUATIONS FOR BAROTROPIC AND SIMPLE BAROCLINIC FLOWS
(American Meteorological Society, 1953)An n-level generalization of the 2½-dimensional model is derived by specialization of the complete three-dimensional quasi-geostrophic equations. In the case n = 1, it reduces to the two-dimensional single-layer barometric ...
