Observations of Saharan Aerosols: Results of ECLATS Field Experiment. Part II: Broadband Radiative Characteristics of the Aerosols and Vertical Radiative Flux Divergence
(American Meteorological Society, 1987)The results presented in this paper are a part of those obtained during the ECLATS experiment The broadband radiative characteristics of the Sahelian aerosol layer and the vertical radiative flux divergence within the dust ... -
Observations of Saharan Aerosols: Results of ECLATS Field Experiment. Part I: Optical Thicknesses and Aerosol Size Distributions
(American Meteorological Society, 1987)A series of ground-based and airborne observations of desert aerosols, the ECLATS experiment was carried out in December 1980 in the vicinity of Niamey (Niger). This paper deals with aerosol optical thicknesses and size ... -
Concerning the Relationship between Evapotranspiration and Soil Moisture
(American Meteorological Society, 1987)Evapotranspiration observations have traditionally been scaled by potential evapotranspiration as a means of unifying the soil moisture-evapotranspiration relationship under a variety of meteorological conditions. However, ... -
Empirical Analysis of Passive Microwave Observations from Bbaskara-II SAMIR and Remote Sensing of Atmospheric Water Vapor and Liquid Water
(American Meteorological Society, 1987)Empirical and statistical techniques have been used to examine a large dataset of near-nadir brightness temperature measurements at 19, 22 and 31 GHz over tropical oceans from the Satellite Microwave Radiometer (SAMIR) ... -
Numerical Modeling of Hailstorms and Hailstone Growth. Part I: Preliminary Model Verification and Sensitivity Tests
(American Meteorological Society, 1986)This paper is the first in a three part series describing numerical simulations of hailstorms and hailstone growth using a two-dimensional, time-dependent cloud model. In this model. cloud water, cloud ice and rain are ... -
Effect of Elevation and Aspect on Wind, Temperature and Humidity
(American Meteorological Society, 1986)Meteorological patterns around an isolated, conical mountain were analyzed for 2 consecutive years July through October. Nine remote automatic weather stations were deployed on nearly uniform slopes, all four aspects, and ... -
Comments on “Need for Requirement that Details of Seeding Operations Be Adequately Specified”

Aircraft Observations of Transport and Diffusion in Cumulus Clouds
(American Meteorological Society, 1986)A gaseous tracer, sulfur hexafluoride, was used to follow the path of two different AgI cloud seeding aerosols in cumulus clouds. The materials were released at cloud base or midlevels. Plumes sampled at midlevels were ... -
A Method for Coupling a Parameterization of the Planetary Boundary Layer with a Hydrologic Model
(American Meteorological Society, 1986)Deardorff's parameterization of the planetary boundary layer is adapted to drive a hydrologic model. The method converts the atmospheric conditions measured at the anemometer height at one site to the mean values in the ... -
Narrow- and Broad-Band Satellite Measurements of Shortwave Radiation: Conversion Simulations with a General Circulation Model
(American Meteorological Society, 1986)The Oregon State University/Lawrence Livermore National Laboratory general circulation model has been employed as a vehicle for suggesting and exploring various means of converting narrow-band measurements of reflected ... -
The Urban-related Nocturnal Rainfall Anomaly at St. Louis
(American Meteorological Society, 1986)Studies during the Metropolitan Meteorological Experiment (METROMEX) sought to define influences of St. Louis on the summer atmosphere that led to alterations in rainfall. These studies defined how city influences caused ... -
A Minimum Assumption Tornado-Hazard Probability Model
(American Meteorological Society, 1986)One of the principle applications of climatological tornado data is in tornado-hazard assessment. To perform such a hazard-potential determination, historical tornado characteristics in either a regional or tom area are ... -
Comparisons of Aircraft and Tower Measurements around Tarama Island during the AMTEX ‘75
(American Meteorological Society, 1986)During the field observation period of the Air Mass Transformation Experiment in 1975 (AMTEX ?75), one of the boundary-layer research flights of the National Center for Atmospheric Research (NCAR) Electra aircraft was ... -
Hailstone Shape Factor and Its Relation to Radar Interpretation of Hail
(American Meteorological Society, 1986)The shape factor of hailstones, defined as the ratio of their long and short axes (m?/m), has been measured for hailstones from three geographical areas: northeastern Colorado, central Oklahoma and central Alberta. The ... -
Evaluating Precipitation Modification under Drought Conditions for Utah Agriculture
(American Meteorological Society, 1986)The impacts of the 1934 and 1977 droughts in the seven Climatological regions of Utah were examined using a linear programming model that simulated crop and livestock production in Utah for 1979. Crop and range production ... -
Further Exploratory Analysis of the Bridger Range Winter Cloud Seeding Experiment
(American Meteorological Society, 1986)Further exploratory analysis of the Bridger Range Experiment was carried out with 6 h data blocks partitioned from the original 24 h experimental units. The analysis was limited to 6 h periods having a rawinsonde observation, ... -
Low- and Midlevel Cloud Analysis Using Nighttime Multispectral Imagery
(American Meteorological Society, 1986)A multispectral cloud analysis technique using NOAA-7 Advanced Very High Resolution Radiometer (AVHRR) infrared imagery was developed and tested using the AFGL Man-computer Interactive Data Access System (McIDAS) and the ... -
Aerosols in Polluted versus Nonpolluted Air Masses: Long-Range Transport and Effects on Clouds
(American Meteorological Society, 1986)To assess the influence of anthropogenic aerosols on the physics and chemistry of clouds in the northeastern United State, aerosol and cloud-drop size distributions, elemental composition of aerosols as a function of size, ... -
Earth Rotation as a Proxy for Interannual Variability in Atmospheric Circulation, 1860-Present
(American Meteorological Society, 1986)Modern atmospheric and geodetic datasets have demonstrated that changes in the axial component of the atmosphere's angular momentum and in the rotation rate of the solid earth are closely coupled on time scales of up to ...
