Mesoscale Transport and Dispersion of Airborne Pollens
(American Meteorological Society, 1974)Pollen transport and dispersion from generalized area sources was studied by 29 flights to distances of 100 km and heights of 3 km using an aircraft-mounted isokinetic sampler. Tree pollens and ragweed pollen served as ... -
A Method for the Production and Determination of the Characteristics of Water Droplet Aerosols in the Above-Micron Range
(American Meteorological Society, 1974)A generator of water aerosols that produces almost uniform droplets in the above-micron range is described. The operational behavior and the effect of various parameters of the apparatus is reported. Attention is also paid ... -
Errors in the Lidar Measurement of Atmospheric Gases by Differential Absorption
(American Meteorological Society, 1974)An analysis is presented of the lidar measurement of the distribution of atmospheric gases by the differential absorption of scattered energy. The error involved in the measurement of the spatial distribution of the gas ... -
Silver Iodide Plume Characteristics Over the Bridger Mountain Range, Montana
(American Meteorological Society, 1974)A modified NCAR acoustical ice nucleus counter was used in an airborne mode to measure the characteristics of silver iodide plumes released in mountainous terrain. These measurements were a supplement to a winter randomized ... -
Lower Turbulent Zones Associated with Mountain Lee Waves
(American Meteorological Society, 1974)The characteristics of the lower turbulent zone (LTZ) which is associated with mountain lee waves have been investigated through the analysis of aircraft observations made near Boulder, Colo. Numerical filters and statistical ... -
Observational Studies of Mesoscale Cellular Convection
(American Meteorological Society, 1974)An observational study of mesoscale cellular convection occurring over vast regions of the North Atlantic and North Pacific has been done for the period 1 January 1969 through 30 June 1970. Satellite cloud photography from ... -
Calibration and Tests of a Yaw Sphere-Thermometer System for Sensible Heat Flux Measurements
(American Meteorological Society, 1974)A yaw sphere-thermometer assembly, to measure sensible heat flux density by the eddy correlation method, was built following the design of Tanner and Thurtell. Wind tunnel experiments indicate that the sphere constant ... -
Vertical Exchange Measurements in the Lower Troposphere Using ThB (Pb-212) and Radon (Ru-222)
(American Meteorological Society, 1974)Various methods of determining vertical eddy diffusion coefficients in the planetary boundary layer from two natural radioactive tracers, radon (Rn-222) and ThB (Pb-212), are presented and discussed. In all cases, it is ... -
Thunderstorm Potential of Cold Air Cumulonimbi
(American Meteorological Society, 1974)Cumulonimbi are often reported in cold air during winter months in northern Europe but thunderstorms are observed much less frequently. This suggests that some cold air cumulonimbi cannot develop into thunderstorms. The ... -
A Statistical Model for the Surface Relative Humidity
(American Meteorological Society, 1974)The beta distribution is the model for frequency distributions of relative humidity observations. The standard chi-square (?2) test measures the goodness of fit of the beta distribution model to the observed data base. ... -
Formulation of the Lateral Boundary Conditions for the NCAR Limited-Area Model
(American Meteorological Society, 1974)The Limited-Area Model (LAM) developed at the National Center for Atmospheric Research for use in conjunction with the NCAR Global Circulation Model is described including details of the lateral boundary conditions. One ... -
Factor Analysis of Coastal Air and Water Temperatures
(American Meteorological Society, 1974)Examination of the orthogonally rotated factors of a common factor analysis program has revealed a relationship between water temperatures and coastal air temperatures. However, this statistical relationship occurred only ... -

A Comparison of Satellite-Derived, Low-Level and Cirrus-Level Winds with Conventional Wind Observations
(American Meteorological Society, 1973)The suitability of satellite-derived, low-level and cirrus-level winds for application to operational weather analyses in low latitudes is established. It is shown that satellite-derived, low-level winds compare very ... -
