Holzworth or University of Washington, Seattle. Murican heavy metal band formed originally in the 1980s, Lightning Strikes has had a long and somewhat complicated history. These findings not only improve our understanding of why lightning is less common over the ocean, but also how lightning, storms, and atmospheric circulation may be impacted by climate change in the future.Ībout the researchers: This project was a collaboration between many researchers including Wei Gong, Zengxin Pan, Feiyue Mao, Lin Zang, Xin Lu, and Jianhua Yin of Wuhan University, Daniel Rosenfeld and Avichay Efraim of The Hebrew University of Jerusalem, Yannian Zhu of Nanjing University and Joel A. If fewer ice particles form, there is less chance for cloud electrification. Almost 1 out of 4 lightning strike victims are aged 15 through 24. Lightning can strike anyone, but certain groups may be more at risk. 59 of lightning strike victims engage in outside leisure activities on the weekend. Many lightning victims are caught outside during a storm because they did not act promptly to get to a safe place, or they go back outside too soon after a storm has passed. Lightning strikes cause more deaths on weekends, mostly on Saturday. Large aerosols such as salt particles weaken convection (updrafts and downdrafts) within the cloud, and this promotes droplets to fall as rain instead of rising upward to form ice. Lightning is unpredictable and can strike outside the heaviest rainfall areas or even up to 10 miles from any rainfall. They also show how inĬontrast, fine aerosols, which are more common over land, promote cloud electrification. In their recent study, published in Nature Communications, the authors share how coarse marine aerosols, such as salt from sea spray, can reduce the frequency of lightning. As the ice and water collide, electrons are stripped off the molecules, resulting in the electrification of the cloud. When these are eventually pushed downward by a downdraft, the frozen droplets collide with uprising liquid droplets. In such clouds, water droplets that are drawn to the top of the cloud by updrafts freeze. Lightning is often associated with storm clouds, which are turbulent masses of water droplets. Lightning is a spark of electricity caused when two electrically charged regions neutralize each other. In 2012, 28 people died from lightning in the United States. But lightning does injure about 240,000 people and kill 24,000 each year, according to a 2003 study. Most of those strikes don’t touch anyone. To get to the bottom of this, a collaborative team of researchers from Wuhan University and Nanjing University in China, The Hebrew University of Jerusalem, and the University of Washington, Seattle, USA, analyzed weather, aerosol, and lightning activity data from over Africa and the continent’s adjacent oceans. Around the world, lightning occurs about 100 times every second of every day. The reduced frequency of lightning over the oceans is a phenomenon that has thus far eluded a convincing explanation. The amount of lightning in thunderstorms over land is typically greater than that seen in thunderstorms over tropical oceans.
