RISSilver Iodide Plume Characteristics Over the Bridger Mountain Range, Montana
Publisher: American Meteorological Society
Abstract: A modified NCAR acoustical ice nucleus counter was used in an airborne mode to measure the characteristics of silver iodide plumes released in mountainous terrain. These measurements were a supplement to a winter randomized ...
Evaluation of the Bridger Range Winter Cloud Seeding Experiment Using Control Gages
Publisher: American Meteorological Society
Abstract: A randomized exploratory single-area cloud seeding experiment was carried out in the Bridger Range of southwestern Montana during the winters of 1969?72. Seeding was accomplished using ground-based silver iodide (AgI) ...
Microphysical Effects of Wintertime Cloud Seeding with Silver Iodide over the Rocky Mountains. Part II: Observations over the Bridger Range, Montana
Publisher: American Meteorological Society
Abstract: During January 1985 six aircraft sampling flights were made in cloud over the target area of an earlier randomized exploratory cloud seeding experiment in the Bridger Range, Montana. One of the two diver iodide (AgI) ...
Microphysical Effects of Wintertime Cloud Seeding with Silver Iodide over the Rocky Mountains. Part III: Observations over the Grand Mesa, Colorado
Publisher: American Meteorological Society
Abstract: During March 1986, several airborne and ground-based silver iodide (AgI) seeding experiments were conducted over the Grand Mesa, Colorado, during a three-day period of northerly flow and shallow orographic cloud. While ...
Raingage Network Requirements from a Simulated Convective Complex Weather Modification Experiment
Publisher: American Meteorological Society
Abstract: A convective complex weather modification experiment was simulated using Monte Carlo techniques. The purpose was to estimate the optimum raingage density for evaluation of a possible future experiment. The data base consisted ...
Simulating the Influence of Type II Error on the Outcome of Past Statistical Experiments
Publisher: American Meteorological Society
Abstract: Simulations of randomized winter orographic weather modification experiments were used to explore a possible cause of the many inconclusive results from previous statistical experiments. There is increasing evidence that ...
Observations of Silver Iodide Plumes over the Grand Mesa of Colorado
Publisher: American Meteorological Society
Abstract: A series of wintertime airborne tracing experiments was examined to determine some characteristics of the plumes of silver iodide smoke released either from the ground or from an aircraft over the Grand Mesa of Colorado. ...
The Practicability of Dry Ice for On-Top Seeding of Convective Clouds
Publisher: American Meteorological Society
Abstract: Dry ice is shown to be an attractive agent for on-top seeding of convective clouds. A modest payload of small dry ice pellets can effectively seed dozens of clouds, depending on cloud volumes encountered and crystal ...
Field Observations of the Persistence of AgI-NH4I-Acetone Ice Nuclei in Daylight
Publisher: American Meteorological Society
Abstract: A field method of estimating the persistence of a commonly used silver iodide seeding agent is described. The method involved measurement of the AgI plume structure at two downwind distances from the ground generator(s). ...
