An Analysis of Turbulence Statistics at Fort Wayne, Indiana
(American Meteorological Society, 1968)Published measurements of wind speed, wind direction and turbulence levels made at Fort Wayne, Ind., provide a basis for an analysis of mesoscale variations over the Fort Wayne area. Average values of data from Vector Vane ... -
Concurrent Airplane and Balloon Measurements of Atmospheric Boundary-Layer Structure over a Forest
(American Meteorological Society, 1968)During three observational periods in the spring and summer of 1964, an experimental program was conducted over a forested area in northeastern Wisconsin in which airplane measurements in the planetary boundary layer were ... -
Turbulence and Wind Speed Spectra within a Japanese Larch Plantation
(American Meteorological Society, 1968)Mean horizontal wind speed profiles within and above a plantation of Japanese larch were obtained. A log-profile analysis of above-vegetation wind speeds yielded a wide range of values for the roughness length parameter ... -
Application of the Microaerofluorometer to the Study of Dispersion of a Fluorescent Aerosol into a Selected Atmosphere
(American Meteorological Society, 1968)An electro-optical device, the Goldberg Microaerofluorometer (MAFIA), has been developed to provide a nearly instantaneous fluorescent aerosol count. It has an effective sampling rate of 12 liters min?1 and a useful ... -
The Mesoscale Wind Field in an Occlusion
(American Meteorological Society, 1968)Data from a 10-site mesoscale rawinsonde network are used to document a number of features in the wind field in a mature cyclone of moderate intensity. The general nature of, and some particular phenomena in, the mesoscale ... -
Some Characteristics of Strong Wind Periods in Coastal East Antarctica
(American Meteorological Society, 1968)The intensity and duration of strong wind events at three Australian stations in East Antarctica are discussed using four years of records. The longer term events are examined in relation to the pressure, temperature, wind ... -
Beneficial Aspects of the Tropical Cyclone
(American Meteorological Society, 1968)This paper deals almost entirely with beneficial rains. Records of drought severity in the climatic divisions of the states are examined. The rainfall data from tropical cyclones which have moved over drought-stricken areas ... -
Grid Telescoping in Numerical Weather Prediction
(American Meteorological Society, 1968)A technique is presented as a means of treating problems in meteorology by numerical prediction on a fine scale. The method involves solution of numerical equations on a grid of data points in the usual way. Then, results ... -
Modifications to an Operational Numerical Weather Analysis System and Application to Rainfall
(American Meteorological Society, 1968)Modifications are made to an operational numerical weather analysis procedure concerning, chiefly, generation of the first approximation and consistency of analyzed scale with information density, with a view to extending ... -
An Elementary Mathematical Model for the Interpretation of Precipitation Probability Forecasts
(American Meteorological Society, 1968)A mathematical model is constructed for interpreting precipitation probability forecasts which have areal connotations. The paper is chiefly concerned with a simple discrete form of the model, in which a forecast area is ... -

Evaluation and Design of Wind Vanes
(American Meteorological Society, 1967)Wind vane motion constants (damping ratio, natural wavelength and decay distance) are derived in a way which can accomodate both mechanical friction and the presence of a propeller. The motion is shown to be insufficiently ... -
An Airborne Continuous Cloud Particle Replicator
(American Meteorological Society, 1967)An instrument for collecting cloud particles from an airplane has been developed. Cloud particles are captured and permanently replicated using the well known Formvar technique. From the continuous record of hydrometeor ... -
A Calibration of the NCAR Acoustical Ice Nucleus Counter
(American Meteorological Society, 1967)The NCAR acoustical ice nucleus counter was calibrated against a Bigg-Warner Weather Bureau type chamber modified as a mixing chamber. The mixing chamber was in turn calibrated against the CSU-NSF isothermal diffusion cloud ... -
On the Infrared Transmission Through Cirrus Clouds and the Estimation of Relative Humidity from Satellites
(American Meteorological Society, 1967)On the basis of satellite and other types of information, it is shown, both on observational and theoretical grounds, that cirrus clouds have a higher transmission for radiation at 10 ? than for radiation at 6 ?. Thus, in ... -
Doppler Radar Observation of Drop Sizes in Continuous Rain
(American Meteorological Society, 1967)Doppler radar observations were made of continuous rain in a situation where particles with terminal velocities of up to 5 m sec?1 were present above the 0C isotherm. It is shown that under these conditions, the presence ...
