The Use of Permutation Techniques in Evaluating the Outcome of a Randomized Storm Seeding Experiment
(American Meteorological Society, 1996)The inappropriateness of standard parametric inference procedures for the analysis of weather modification experiments has been well documented and has led to permutation tests being strongly recommended by, among others, ... -
Study of Environmental Pollution in a Hail-Protected Area
(American Meteorological Society, 1996)Fourteen years of observations of the content of cloud seeding agents in the air and water of a hail-protection area in the Republic of Moldova are summarized. During the observational period, the amount and type of the ... -
Results of Experiments on Convective Precipitation Enhancement in the Camaguey Experimental Area, Cuba
(American Meteorological Society, 1996)Experiments on randomized seeding of individual convective clouds and cloud clusters were conducted in the Camaguey experimental area, Cuba, from 1985 through 1990 in order to elucidate whether cold-cloud dynamic seeding ... -
The Effects of Desert Particles Coated with Sulfate on Rain Formation in the Eastern Mediterranean
(American Meteorological Society, 1996)Measurements of aerosol composition in the eastern Mediterranean reveal that sulfate is found in most aerosol particles. Some of the large particles contain mixtures of chemicals such as sulfate and sea salt. The most ... -
Seeding Effectiveness The Interaction of Desert Dust and the Southern Margins of Rain Cloud Systems in Israel
(American Meteorological Society, 1996)Statistical analyses suggest that cloud seeding has caused a net increase of rainfall only in northern Israel. These analyses also identify the reported desert dust as a detrimental factor for the seeding effectiveness. ... -
Ice Nuclei, Rainwater Chemical Composition, and Static Cloud Seeding Effects in Israel
(American Meteorological Society, 1996)This study analyzed the temporal and spatial variation of natural ice nuclei (IN), total suspended particles (TSP), and rainwater chemical composition (RCC) in Israel. This research is complementary to the statistical ... -
Assessing the Potential for Rain Augmentation The Nelspruit Randomized Convective Cloud Seeding Experiment
(American Meteorological Society, 1996)The experimental design, analyses, and results of the first Nelspruit randomized cloud seeding experiment are described. The experiment ran for three years, commencing in October 1984, and involved the on-top seeding of ... -
Project Mountain Valley Sunshine Progress in Science and Technology
(American Meteorological Society, 1996)In order to improve the cloud seeding reaction, the basic processes in cloud microphysics and dynamics were critically examined. The disadvantage of the large temperature dependence in heterogeneous ice nucleation, as well ... -
Seeding Convective Clouds with Ice Nuclei or Hygroscopic Particles: A Numerical Study Using a Model with Detailed Microphysics
(American Meteorological Society, 1996)Simulations of seeding clouds for rain enhancement with ice nuclei (IN) or hygroscopic particles were conducted using a numerical model of an axisymmetric convective cloud with detailed treatment of both warm and cold ... -
Australian Winter Mountain Storm Clouds: Precipitation Augmentation Potential
(American Meteorological Society, 1996)Two Australian winter mountain storm field research projects were conducted by the Commonwealth Scientific and Industrial Research Organisation Division of Atmospheric Research and the Desert Research Institute Atmospheric ... -
The Effects of Mountain Lee Waves on the Transport of Liquid Propane-Generated Ice Crystals
(American Meteorological Society, 1996)A combination of rawinsonde balloon ascent rates, low-elevation aircraft, and ground-based tracer sampling measurements are presented. These data indicate that mountain-induced gravity waves have a significant impact on ... -
Feeder-Cell Ingestion of Seeding Aerosol from Cloud Base Determined by Tracking Radar Chaff
(American Meteorological Society, 1996)Questions of delivery, transport, and dispersion of cloud seeding aerosol in a convective feeder cloud are addressed by using radar chaff as a surrogate for aerosol and tracking it with circular-polarization radar. In a ... -

Combined Use of Three Techniques for Studying Transport and Dispersion in Cumuli
(American Meteorological Society, 1996)The results from three methods for studying transport and dispersion in cumuli are compared. These three methods include two tracer techniques and a numerical simulation. The tracers, SF6 and radar chaff, were simultaneously ... -
Turbulence Spectra and Eddy Diffusivity over Forests
(American Meteorological Society, 1996)The main objectives of this observational study are to examine the stability dependence of velocity and air temperature spectra and to employ the spectral quantities to establish relations for eddy diffusivity over forests. ... -
An Assessment of the Quality of Forecast Trajectories
(American Meteorological Society, 1996)Forecast and ?analysis? (reference) trajectories were computed from six sites over North America at three altitudes (500, 1000, and 1500 m above ground) twice a day for a one-year period using Nested Grid Model wind fields. ...
