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 provides simple descriptions and informative illustrations on moisture and resulting fog. Next, from USA Today, comes the Understanding Clouds and Fog (3) Web site. This extensive site provides a great section on fog that includes descriptions of various types: advection, radiation, steam, precipitation, upslope, and valley fog. The fourth site (4), maintained at University of California at Boulder by Professor Robert Tardif, is entitled Interactions Between Aerosols and Fog (5). Visitors will find descriptions of aerosol properties and fog characteristics, as well as how aerosol causes the formation of fog. The Natural Hazard Statistics (6) Web site is provided by the National Weather Service's Office of Climate, Water, and Weather Services. The site provides statistical information on fatalities, injuries, and damages caused by weather related hazards including fog. For example, in 2001, there were seven fatalities and 67 injuries attributed to the visibility thief. The seventh site, from Web Weather for Kids of the University Cooperation for Atmospheric Research, is called Make Fog in a Jar (7). Letting students see first hand how fog forms, this simple activity can be completed with a little help from an adult, some paper, a jar, warm water, matches, and a bag of ice. The last Web site, GOES Nighttime Fog and Low Cloud Imagery (8), is maintained by the Office of Research and Applications at NOAA. The site shows fog depth images and animations from around the US. These are generated from two GOES InfraRed (IR) channels that are combined to create a product for the detection of fog and low stratus clouds at night.
