Lightning and Its Impacts
Ronald L. Holle - Holle Meteorology & Photography, Oro Valley, Arizona
"About 25 million cloud-to-ground lightning flashes hit the surface of the United States every year. These flashes are well detected in the U.S. and many other countries by national lightning detection technology. In addition, other specialized regional networks detect many more cloud flashes that can extend over 100 km in length across the sky. Continuing advances in extremely long-range lightning detection are showing lightning over remote oceans and land masses around the globe. Every cloud-to-ground lightning strike is fully capable of causing casualties and damages. For this reason, lightning data are used in forestry, utilities, aviation, weather services, military, industrial, recreation, media, and insurance applications. The activity, location, time trends, and medical issues of lightning casualties will be described. The talk will conclude with a set of updated lightning safety recommendations."
