Problems with the Current Definitions of the Standard Deviation of Wind Direction
(American Meteorological Society, 1987)Much of the ongoing debate about how to define the standard deviation of wind direction can be attributed to the widespread implementation of a faulty method of defining it in wind-measuring instrumentation in the previous ... -
Infrared and Visible Satellite Rain Estimation. Part II: A Cloud Definition Approach
(American Meteorological Society, 1987)This study examines the relationships between satellite infrared clouds and rainfall, and infrared-threshold visible clouds and rainfall. Clouds are defined by the outline of the 253 K isotherm. Cloud infrared area was ... -
Aircraft Observations of Meteorological Conditions along Africa's West Coast between 30°–35° South
(American Meteorological Society, 1987)Meteorological conditions along the west coast of Africa between 30° and 35°S were monitored by means of an instrumented aircraft flown at a height of 150 m over the continental shelf and coastal margin. Case studies, ... -
Infrared and Visible Satellite Rain Estimation. Part I: A Grid Cell Approach
(American Meteorological Society, 1987)The relationships between satellite-viewed cloudy (or partly cloudy) grid cells and the variability of the precipitation contained therein are explored. Using a 32 km grid and 30 min interval visible, infrared and radar ... -
Ground-Based, High-Resolution Measurements of the Spatial and Temporal Distribution of Rainfall
(American Meteorological Society, 1987)Preliminary data from ground-based measurements of rainfall using an optical disdrometer and high-resolution rain gage network are described. The recurrence of the rain period is shown to be non-Poisson with evidence of ... -
Comments on “Delayed Effects of Cloud Seeding with Silver Iodide”
(American Meteorological Society, 1987)tract -
Parameterization of Radiative Flux Profiles within Layer Clouds
(American Meteorological Society, 1987)The vertical structure of radiative flux profiles within clouds can have a significant impact on the thermodynamic processes that maintain and dissipate the clouds, particularly in the case of marine stratus and stratocumulus. ... -
Radar Observation of Snowfall from a Natural-Draft Cooling Tower Plume
(American Meteorological Society, 1987)One of the potential atmospheric effects of energy dissipation at large power parks is the mesoscale modification of the precipitation field. Meteorological conditions favorable for such an influence mainly correspond to ... -

Seasons, Singularities, and Climatic Changes over the Midlatitudes of the Northern Hemisphere during 1899–1969
(American Meteorological Society, 1987)The annual regime of atmospheric circulation over the midlatitudes of the Northern Hemisphere for the years 1899?1969 was determined by factor analysis of daily frequencies of Dzerdzeevskii's Northern Hemisphere extratropical ... -

The Influence of Soil and Vegetation on the Development of Mesoscale Circulations
(American Meteorological Society, 1987)A two-dimensional mesoscale model including a detailed representation of the planetary boundary layer, the soil and the vegetation is developed. A sea breeze over flat terrain is simulated, thereby confirming the ability ... -
Climatic Temperature Normals
(American Meteorological Society, 1987)The published 1951?80 daily normals of maximum and minimum temperatures were prepared by interpolating between average monthly values. This study compares the published normal and 30-yr average daily temperatures in the ... -
A Pattern Recognition Technique for Distinguishing Surface and Cloud Types in the Polar Regions
(American Meteorological Society, 1987)Measurement of polar cloud cover is important because of its strong radiative influence on the energy balance of the snow and ice surface. Conventional satellite cloud detection schemes often fail in the polar regions ... -
The Numerical Simulation of Drainage Winds in a Small Urban Valley under Conditions with Supercritical Richardson Numbers
(American Meteorological Society, 1987)A two-dimensional numerical model is used to simulate nocturnal drainage flow in a small urban valley with light prevailing winds and conditions of supercritical Richardson numbers (Ri). The model uses a hydrostatic and ... -
Experiments on the Cloud Droplet Collision Efficiency of Cylinders
(American Meteorological Society, 1987)The theory of Langmuir and Blodgett for the droplet collision efficiency was verified by growing rime ice accretions on rotating cylinders in a wind tunnel. The results show that the theory is in excellent agreement with ... -
Estimating Tropical Pacific Rainfall Using Digital Satellite Data
(American Meteorological Society, 1987)Statistical models that estimate tropical Pacific rainfall from the National Oceanic and Atmospheric Administration's global archive of polar-orbiter satellite data have been derived and tested. These rainfall models are ... -
Aspects of the Load Circulation at the Grand Canyon during the Fall Season
(American Meteorological Society, 1987)The atmosphere and circulation of air within, above, and around the Grand Canyon of the Colorado River was studied from an instrumented aircraft and from ground-based instruments in September and October 1984. Several ... -
Modeling Ambient Carbon Monoxide Trends to Evaluate Mobile Source Emissions Reductions
(American Meteorological Society, 1987)Regression models have been used with poor success to detect the effect of emission control programs in ambient concentration measurements of carbon monoxide. An advanced CO regression model is developed whose form is based ... -
Testing for Climate Change: An Application of the Two-Phase Regression Model
(American Meteorological Society, 1987)A statistical test for detecting a change in the behavior of an annual temperature series is presented. The test is based on the two-phase regression model. By trading the hypothesized time of change as an unknown parameter, ...
