Monitoring and Predicting El Niño Invasions
(American Meteorological Society, 1974)Southern Oscillation indices (differences in sea level atmospheric pressure between Easter Island and Darwin, Australia, and between Juan Fernandez Island and Darwin) were treated so as to emphasize interannual changes and ... -

Aircraft Water Vapor Measurements Utilizing an Aluminum Oxide Hygrometer
(American Meteorological Society, 1974)A hygrometer for water vapor measurements from an aircraft was developed. An aluminum oxide hygrometer mounted in an aircraft Rosemount air temperature scoop was flown on the NASA Convair 990 and on a USAF B-57 aircraft. ... -
Objective Determination of the Noise Level in Doppler Spectra
(American Meteorological Society, 1974)A method is described for the objective determination of the noise level in Doppler spectra. The method makes use of the physical properties of white noise and is suitable for automatic computation. It is shown that the ... -
Measurement of Rainfall Rates by Lidar
(American Meteorological Society, 1974)Monostatic lidar is explored as a means for determining the rainfall rate over an extended atmospheric path with a spatial resolution comparable to that of rain gages. An empirical relationship is established between the ... -
Collisions of Raindrops with Chaff
(American Meteorological Society, 1974)The purpose of this study is to assess the entrainment by rain of chaff which is used to track air motions by radar. Experiments are described where 214 individual water drops with diameters of 4.9 mm and falling at 78% ... -
Projected Utilization of Warm Fog Dispersal Systems at Several Major Airports
(American Meteorological Society, 1974)Hourly surface weather observations are combined with air traffic records to calculate projected utilization of operational warm fog dispersal systems at 15 Air Force bases in the United States and Europe, and at one ... -
Possible Influence of Evaporation Below Cloud Base on Rain Enhancement
(American Meteorological Society, 1974)The possibility is discussed that evaporation in the subcloud layer might be a major factor controlling the efficiency of rain enhancement by seeding, under the simplistic assumption that seeded clouds produce larger ... -
Silver Halides and Iodine Monobromide Systems as Freezing Nuclei
(American Meteorological Society, 1974)Silver chloride, bromide and iodide hydrosol particles were studied as freezing nuclei. Ice nucleation was enhanced through the exchange of iodine ions on the surface of solid silver iodide, using iodine monobromide. Drops ... -
Application of a Diagnostic Richardson Number Tendency to a Case Study of Clear Air Turbulence
(American Meteorological Society, 1974)An index for the development of clear air turbulence on a synoptic scale is derived using the time rate of change of the Richardson number following the air motion, the so-called diagnostic Ri tendency. The method used in ... -
A Study of Self-Similarity in Turbulence Measured at an Urban Site
(American Meteorological Society, 1974)The self-similarity concept has proved useful in describing turbulence for aircraft design purposes. There is an increasing awareness of the interaction of the turbulent planetary boundary layer and buildings and structures. ... -
Precipitable Water and Its Relationship to Surface Dew Point and Vapor Pressure in Athens
(American Meteorological Society, 1974)The relationship between the total amount of precipitable water and surface dew point and the square root of surface vapor pressure have been examined in Athens on the basis of mean monthly values. The correlation coefficients ... -
Polar Boundary Conditions in Zonally Averaged Global Climate Models
(American Meteorological Society, 1974)We consider global climate models based on zonally averaged balance relations. Inherent boundary conditions require the meridional fluxes of non-negative properties (temperature, humidity, energy, etc.), as well as the ... -
The Typhoons of October 1970 in the South China Sea: Intensification, Decay and Ocean Interaction
(American Meteorological Society, 1974)In October 1970 the South China Sea experienced three typhoons. Meteorological and oceanographic data were examined in an attempt to explain why the typhoons underwent intensity changes while over the South China Sea. The ... -
Influence of the Tropopause Height on the Global Stratospheric Aerosol Burden and Implications for the Recent Increase in Ozone
(American Meteorological Society, 1974)Seasonal tropopause height variations are utilized in studying the global stratospheric aerosol burden and possible ozone asymmetries and long-term variations. It is concluded that an intimate relationship between tropopause ... -

On the Computation of Isobaric Wet-Bulb Temperature and Saturation Temperature over Ice
(American Meteorological Society, 1974)Non-iterative methods for computing isobaric wet-bulb temperature and the temperature at the lifted sublimation level are presented. These quantities are then computed by these direct techniques and compared to values ...
