Lightning can induce powerful transient voltage spikes on the power lines that can destroy solid-state electronics in the space of a heartbeat. Proceed with caution. This lightning bolt of energy that is let out is called a leader stroke. Thundersnow. We still don't know what triggers the … A new technique can remotely sense strong electrical fields within storm clouds. No one is sure why lightning bolts follow a zigzag path as they move. A lightning current may also hit a tree, building, or object and then travel to you. Lightning rods and metallic conductors can be used to protect a structure by intercepting and diverting the lightning current into the ground as harmlessly as possible. ), 9.1 – When severe adverse weather conditions (snow, ice, wind, rain, lightning, etc.) One lightning flash could run a whole power station – and there are 8 million strikes around the Earth every day. lightning mostly happens when there are a lot of clouds in the sky because lightning is the result when ice particles with negative charge is rubbed with another ice particle but with positive charge. A lightning current may also travel on the ground from the site of … It can also travel from person to person or from telephone wires to you. Lightning is a significant weather hazard and occurs at an average rate of 50 to 100 discharges per second worldwide. Lightning and thunder can occur with any type of winter precipitation - including snow, sleet ('thundersleet') and freezing rain. Most lightning happens inside a cloud, but sometimes it happens between the cloud and the ground. It will make a flash of lightning. It isn't nearly as pretty, but it is fascinating nonetheless. Lightning Strikes. Source: Geophysical Research Letters The University of … An adverse operating condition may result from climatic conditions (snow, ice, wind, rain, lightning, etc. Lightning is a naturally occurring electrostatic discharge during which two electrically charged regions in the atmosphere or ground temporarily equalize themselves, causing the instantaneous release of as much as one gigajoule of energy. Or, a leader stroke can go from the cloud to another cloud. Yes, that was a pun. Strong winter snowstorms and blizzards commonly produce lightning strikes, a phenomenon referred to as 'thundersnow'. Lightning may hit you directly when you are in an open area or outdoors. Above: Christmas season lightning in St. Louis in December 2012. When Ice and Lightning Align . The ground's positive charge concentrates around anything that sticks up - trees, lightning conductors, even people! A weird thing happens when ice freezes under the influence of an electric field. Strikes can cause cardiac arrest and severe burns, but 9 of every 10 people survive. It can go from the cloud to the ground. One of my favorite movies called Sweet Home Alabama had a scene in it where lightning struck the sand and created a beautiful glass sculpture. Finding out that this was a figment of Hollywood's imagination, I learned what really happens when lightning strikes the sand. The average American has about a 1 in 5,000 chance of being struck by lightning during a lifetime. The main bolt or stroke will go back up to the cloud. A build up of positive charge builds up on the ground beneath the cloud, attracted to the negative charge in the bottom of the cloud.
