Observations of Cloud Condensation Nuclei, Sodium-Containing Particles, Ice Nuclei and the Light-Scattering Coefficient Near Barrow, Alaska
(American Meteorological Society, 1976)Measurements of the concentrations of cloud condensation nuclei (CCN), sodium-containing particles (SCP) and ice nuclei (IN), and the aerosol light-scattering coefficient were made near Barrow, Alaska, from 8?28 March 1970. ... -
Further Comments on “The Effect of Tropospheric Temperature Lapse Rates on the Ascent Rates of Pilot Balloons”
(American Meteorological Society, 1976)Observations using a double-theodolite system for tracking pilot balloons were made to further examine the effects of temperature lapse rates on pibal ascent rates. It was found that under stable atmospheric conditions ... -
On the Role of Strong Winds in Damage to Crops by Hail and Its Estimation with a Simple Instrument
(American Meteorological Society, 1976)Surface winds which accompany the fall of hail have a profound effect on crop damage. Quantitative estimates of the horizontal and total flux of hailstone kinetic energy can be made with simple theoretical considerations ... -
Wind Speeds Required to Drive Straws and Splinters into Wood
(American Meteorological Society, 1976)Laboratory experiments duplicating the tornadic phenomenon in which small projectiles are driven into various objects such as posts or trees have established the penetration of straws and splinters into various kinds of ... -

On the Response of Hemispheric Mean Temperature to Stratospheric Dust: An Empirical Approach
(American Meteorological Society, 1976)The cooling effects of stratospheric dust and the corresponding response times for hemispheric mean temperature changes are studied using an empirical approach and a simple time-dependent formulation. The approach couples ... -
A Multi-Level Model of the Planetary Boundary Layer Suitable for Use with Mesoscale Dynamic Models
(American Meteorological Society, 1976)In this paper a simple model of the planetary boundary layer (PBL) is proposed. The surface layer is modeled according to established similarity theory. Above the surface layer a prognostic equation for the mixing length ... -
The Regionalization of Climate in the Western United States
(American Meteorological Society, 1976)The western United States is divided into climatic regions based on the air masses that predominate during the winter and summer. Equivalent potential temperature, chosen because it apparently best reduces the effect of ... -
Changes in Temperature from Month to Month for Central England for a Quintile Distribution
(American Meteorological Society, 1976)Anomalies from the respective decadal means of the monthly mean temperatures for central England covering a period of 250 years are ranked to form a quintile distribution. Contingency tables are then prepared which show ... -
Error Estimation in Wind Fields Derived from Dual-Doppler Radar Measurement
(American Meteorological Society, 1976)Variance in horizontal and vertical winds are predicted when these components are computed from dual-Doppler velocity measurements combined with terminal velocity estimates and the continuity equation. Errors in horizontal ... -
Range Statistics as Estimators of Intensity of Turbulence at Diablo Canyon
(American Meteorological Society, 1976)Simultaneous measurements of the standard deviation of the azimuth and vertical wind direction fluctuations from a digital recording system and the range in wind direction fluctuations from an analog recording system have ... -
Dynamics of an Urban Temperature Field—A Case Study
(American Meteorological Society, 1976)Surface and airborne temperature and air pollution data collected in Calgary's urban area show the formation of a multiple-celled heat island at street level. Temperature gradients and their variability correlated with ... -
Experiments on Collection Efficiency. II. The Collection of a Cylinder at Aircraft Speed
(American Meteorological Society, 1976)The results of an experiment determining the collection efficiency of a cylinder at aircraft speeds are presented and compared with the theoretical computations of Langmuir and Blodgett. It was found that the agreement was ... -
Effects of Atmospheric Parameters on the Concentration of Photochemical Air Pollutants
(American Meteorological Society, 1976)This paper presents the results of a study in which a numerical model for photochemical air pollution was used to assess the effect of atmospheric parameters on concentration levels of both primary and secondary air ... -
Microenvironmental Modification by Small Water Droplet Evaporation
(American Meteorological Society, 1976)A mathematical model is developed to predict the microclimatic modification of air near the ground by the evaporation of an ultrafine water mist. The model equations with realistic parameters and boundary values are solved ... -
Vorticity and Divergence Fields within Tornadic Storms from Dual-Doppler Observations
(American Meteorological Society, 1976)Tornadic storms passed between the two NSSL Doppler radars on 20 April and 8 June, 1974. Both radars simultaneously collected Dopplar data throughout these storms. From the derived velocity fields, vorticity and divergence ... -
Long-Distance Transport of 2,4-D
(American Meteorological Society, 1976)Ambient 2,4-D herbicide concentrations in south-central Washington's grape growing areas can reach damaging levels due to aerial 2,4-D applications to wheat fields tens of miles removed from the affected areas. An atmospheric ... -
Experimental Investigation of the Radar Cross Section of Cloud-to-Ground Lightning
(American Meteorological Society, 1976)A 10 cm radar was employed in an effort to measure the radar cross section of cloud-to-ground lightning channels and its temporal variation. A data acquisition system was developed which is capable of recording the amplitude ... -
