A Review of Cloud Seeding Experiments to Enhance Precipitation and Some New Prospects

چکیده
Water is one of the most basic commodities on earth sustaining human life. In many regions of the world, however, traditional sources and supplies of ground water, rivers and reservoirs, are either inadequate or under threat from ever-increasing demands on water from changes in land use and growing populations. In many countries water supplies frequently come under stress from droughts and increased pollution in rivers, resulting in shortages and an increase in the cost of potable water. Ground water tables have been steadily decreasing in many areas around the world where ground water is one of the primary sources of freshwater. This is particularly evident in the southwest United States and Mexico. To help alleviate some of these stresses, cloud seeding for precipitation enhancement has been used as a tool to help mitigate dwindling water resources. While many countries conducting weather modification activities are located in semiarid regions of the world, several countries in the Tropics such as Indonesia, Malaysia, India, and Thailand are also involved in weather modification activities. Although these countries receive a relatively large amount of rainfall, a 5% below normal rainfall year translates into a drought for them due to their infrastructure and agricultural practices that are more water intensive than in other parts of the world. Weather modification activities to enhance water supplies have been conducted for a wide variety of users including water resource managers, hydroelectric power companies, and agriculture. Only a small part of the available moisture in clouds is transformed into precipitation that reaches A Review of Cloud Seeding Experiments to Enhance Precipitation and Some New Prospects

Cloud Seeding Experiment
The experimental data are the result of a series of weather modification experiments conducted in south Florida from 1968 to 1972. These experiments were designed to test a hypothesis that massive injection of silver iodide into cumulus clouds can, under specified conditions, lead to cumulus growth, thereby increased precipitation. On each of 52 days that were deemed suitable for cloud seeding,...
متن کاملAnother Wintertime Cloud Seeding Case Study with Strong Evidence of Seeding Effects
In the 1990s numerous winter orographic cloud seeding experiments were conducted over Utah’s Wasatch Plateau. Several previously published case studies successfully documented the physical response in clouds and precipitation to ground-based seeding with silver iodide and liquid propane. A previously unpublished case study that shows additional evidence of positive seeding effects is presented ...
متن کاملImplementation of a Silver Iodide Cloud-Seeding Parameterization in WRF. Part II: 3D Simulations of Actual Seeding Events and Sensitivity Tests
Four cloud-seeding cases over southern Idaho during the 2010/11 winter season have been simulated by the WeatherResearch and Forecasting (WRF)model using the coupled silver iodide (AgI) cloud-seeding scheme that was described in Part I. The seeding effects of both ground-based and airborne seeding as well as the impacts of model physics, seeding rates, location, timing, and cloud properties on ...
متن کاملCloud Systems and Precipitation Processes in Pacific Coast Storms
From the records obtained during the Weather Bureau Artificial Cloud Nucleation Project carried out in western Washington State during the winters of 1952-53 and 1953-54, i t is possible to study the nature of some of the precipitation processes evident in that locality, and to form a preliminary generalized picture of certain types of cloud systems involved. Evidence is presented of natural se...
