Description:

This Topic in Depth begins with a Web site from the Oklahoma Weather Modification Program called Cloud Physics - The Basics (1 ). Students are encouraged to initiate a debate on the controversy surrounding the issue of inducing or enhancing precipitation. Next, the Texas Water Resources Institute Web site, Does Weather Modification Really Work? (3 ) provides a more basic description of cloudseeding. The site offers several categories including The Science of Cloud Seeding, A Brief History of Weather Modification in Texas, Legal and Policy Issues, Current and Future Activities, and more. The Western Kansas Weather Modification Program offers the next site, Aircrew Pictures 2001 (4 ). The page contains pictures of the planes and crew involved in the program as well as pictures from the plane during a mission. Other links on the site contain radar, data, and other information. The next site from ABCNEWS.com is an article entitled Weather as a Weapon? (5 ) The piece explorers what might happen "on some battlefield of the future where the US military could gain a tactical advantage by changing the weather." A discussion on the possibilities of changing the weather, an Air Force research paper and several other links are provided to learn more. The 6th site maintained by the North Dakota State Water Commission is entitled Atmospheric Resources-Photos and Videos (6 ). Here, visitors can find more photographs of cloudseeding equipment and most notably three videos of cloudseeding planes in action. Atmospherics Incorporated, an operations and research company in the field of applied meteorology, provides the next site, The Physical Basis for Seeding Clouds (7 ). The page describes techniques for cloud seeding and has a link to photographs of pyrotechnic seeding devices. The last site provided by North American Weather Consultants, Inc. is titled, Cloud Seeding -Frequently Asked Questions (8 ). The site briefly answers questions such as When did application of modern cloud seeding technology begin?, Is cloud seeding effective?, and Do the commonly used seeding materials pose any direct health or environmental risks?
