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...

This collection of resources, provided by the National Weather Service Forecast Office for the El Paso area, allows users to be their own meteorologists. For example, armed with data such as current temperature, humidity, and windspeed, users may calculate the heat index or wind chill. Using the resources on this page, and providing basic meteorological data such as temperature, air pressure, and...

The first site, offered by stormdisplay.com, is entitled All About....Fog (1). Visitors will find a brief and simple explanation of the weather phenomenon, including how it forms, where it occurs, and how it dissipates. The second site, Atmospheric Moisture (2), is presented by the Naval Meteorological and Oceanography Command Public Affairs Office. This one-page graphically friendly site also...
