50-MILLIBAR PATTERNS AND THEIR RELATIONSHIP TO TROPOSPHERIC CHANGES
(American Meteorological Society, 1956)Data from three recent winters are utilized to study the large changes in the temperature and flow fields at 50 mb. It is reasoned that the major changes in this region arise from the development of an unstable flow pattern ... -
A BAROCLINIC MODEL ATMOSPHERE SUITABLE FOR NUMERICAL INTEGRATION
(American Meteorological Society, 1953)Subject to various approximations, a system of three simultaneous partial differential equations is derived to predict the height of a contour surface, the thickness of the layer from 1000 mb to that surface, and the field ... -

A CASE STUDY OF CONFLUENCE AS RELATED TO THE JET STREAM
(American Meteorological Society, 1951)This is the second report on a continuing project designed to investigate quantitatively the confluence process and associated changes in the strength and location of the mid-tropospheric jet stream. An empirical study has ... -
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 ... -
A CENSUS OF CUMULUS-CLOUD HEIGHT VERSUS PRECIPITATION IN THE VICINITY OF PUERTO RICO DURING THE WINTER AND SPRING OF 1953-1954
(American Meteorological Society, 1955)The analysis of fifteen cloud-census flights confirms the common existence of warm precipitation from trade-wind cumuli. A probability that over-water clouds of certain vertical developments will contain precipitation is ... -
A CHEMICAL TRACER EXPERIMENT IN OROGRAPHIC CLOUDS
(American Meteorological Society, 1956)In the summer of 1954, and experiment was conducted on the Island of Maui, Territory of Hawaii, in which a chemical tracer technique was exployed to ?tag? water droplets sprayed into an orographic cloud from a site near ... -
A COMPARISON BETWEEN GEOSTROPHIC AND NONGEOSTROPHIC NUMERICAL FORECASTS OF HURRICANE MOVEMENT WITH THE BAROTROPIC STEERING MODEL
(American Meteorological Society, 1959)The steering flow of a hurricane is obtained by eliminating the vortex pattern from the total flow field. The evolution of the steering flow is predicted by solving the barotropic nondivergent vorticity equation. Based ... -
A COMPARISON BETWEEN TWO TRANSFORMATIONS USED IN NORMALIZING METEOROLOGICAL DATA
(American Meteorological Society, 1960)No Abstract Available -
A COMPARISON OF THE RESPONSE OF THE NORTH AMERICAN AND EUROPEAN SURFACE PRESSURE DISTRIBUTIONS TO LARGE GEOMAGNETIC DISTURBANCES
(American Meteorological Society, 1959)The persistence of the three-day mean surface pressure distribution in a mid-latitude region centered on the Greenwich meridian is examined in connection with large increases in geomagnetic activity and is compared with ... -
A CONTINUOUS-RECORDING PRECIPITATION PARTICLE SAMPLER
(American Meteorological Society, 1961)No Abstract Available. -
A CONTINUOUSLY RECORDING WATER-CONTENT METER
(American Meteorological Society, 1956)A simple airborne instrument is described which continuously measures the liquid-water content in ?warm? and supercooled clouds. It is largely temperature independent and has a half-value time of approximately 0.5 second. -
A CONVERGENT METHOD FOR SOLVING THE BALANCE EQUATION
(American Meteorological Society, 1958)The nonlinear balance equation is replaced by an infinite system of linear differential equations. This system has a series of solutions which under certain conditions converge toward the solution of the balance equation. ... -
A COORDINATE SYSTEM HAVING SOME SPECIAL ADVANTAGES FOR NUMERICAL FORECASTING
(American Meteorological Society, 1957)No Abstract Available. -
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. ... -
A DEMONSTRATION OF FRONTS AND FRONTAL WAVES IN ATMOSPHERIC MODELS
(American Meteorological Society, 1956)The remarkable similarity between the motions in a heated rotating tank of water (dishpan experiments) and the large-scale motions of the atmosphere has raised the question of the similarity of the details of the motion. ... -
A DESCRIPTIVE THEORY OF THE PHOTO DE-ACTIVATION OF SILVER IODIDE AS AN ICE-CRYSTAL NUCLEUS
(American Meteorological Society, 1959)The photo de-activation of silver iodide as an ice-crystal nucleus is ascribed to the production of photolytic silver at trapping centers in the volume and on the surface of the nucleating particle. Silver produced at the ... -
A DIFFERENT EXPLANATION OF THE "BRIGHT LINE"
(American Meteorological Society, 1947)No Abstract Available -
A DYNAMIC WIND SIMULATOR FOR THE FRICTIONAL BOUNDARY LAYER
(American Meteorological Society, 1959)An experimental model of an electronic analogue computer which solves the two dimensional equations of motion is described in complete meteorological and engineering detail. Several solutions of the equations are illustrated ... -
A FEW FOG DROP-SIZE DISTRIBUTIONS
(American Meteorological Society, 1961)An independent calibration of an instrument called a Particle Counter and the resulting fog drop-size distributions are discussed. The distributions exhibit an increasing number of droplets with decreasing size. The magnitude ...
