Study confirms lightning more powerful over ocean than land

People who live and work along the coasts and coasts of the world may be more susceptible to supercharged lightning, according to new research from the Florida Institute of Technology shows that lightning can be much more potent ocean than on land.

Amitabh Nag, an assistant professor of physical and space sciences in Florida, and Kenneth L. Cummins, a professor of technology research at Florida and the University of Arizona, recently published “The Negative Characteristics of Early Drivers In the breeze on land and the ocean “in the geophysical research charts of the American Geophysical Union.

Scientists analyzed parts of their coast data using Florida and provided by US lightning detection. National Network.

Some earlier indirect observations have led scientists and others believe that seawater strikes tend to be more potent, but the Nag and Cummins study represents the first time an independent measure validated these beliefs.

Lightning scientists break every cloud to ground strikes in threads to better understand how it formed. Many physics are packed in a second fractions of the time when particles charged in cloud shadows are formed in the descendants of electricity channels “Attach” to the charge-responsible electric channels, which rise from the ground Or water to form the familiar zigzag pin.

During its study, which measures current peak of several Earth-to-Earth beam of clouds and oceans from 2013 to 2015, Nag and Cummins have calculated the duration of the “negative leader” – the electric channel reaching below a Storm cloud

When this head hits the ground, a surge, typically with a peak value of approximately 30 kilos amperes, flows upward into the cloud. The duration of the negative leaders of the ocean was considerably shorter than that of the land, indicating that they must bear more costs. This leads to an increase in the highest current of the earth.

Nag and Cummins have found that with water strikes in West Florida, the average length of time was 17 percent lower compared to the ocean than on land, and in East Florida, the median was 21 and 39 percent shorter in two oceanic regions on land.

Using a relationship between leader length and peak lightning current derived in this study, the authors estimate that lightning with peak currents of more than 50 kilos of amps is twice as likely to occur in ocean storms.

These results suggest that people living in or near them are more likely to suffer damage if enlightening storms develop over the oceans and move ashore.

This new understanding of lightning’s nature could inform how offshore infrastructure and ships should be built to minimize the risk of super-powerful thunderstorms formed over the sea.
