Lightening is one of the most common phenomenon occurring in day to day scenario. It is occurring mainly due to the electro-discharge occurring over the clouds. It is one of the most spectacular phenomenon in the natural world.
It is striking our planet with a bolt of electrical energy which is occurring more than three million times daily.
Meteorologists have revealed details about the most extreme lightening bolts ever recorded. They further add that lightening bolts seen over Oklahoma during 2007 were longest ever reported. They were having horizontal distance of 199.4 miles(321km).
Recording Flash of Lightning:
Over the southern France, scientists has recorded a flash of lightning which lasted continuously for 7.74 seconds in 2012. It was one of the longest duration reported.
Experts from the World Meteorological Organization has now announced officially over the added events to its records of weather extremes.
Petteri Taalas who is secretary general for World Meteorological Organization says, “Lightening is a major weather hazard that claims many lives each year.
Improvements over detecting and monitoring these extreme events will improve public safety.”
Satellite data is suggestive of lightening flashes which are spreaded across the sky which is about 30 times every second. Though it is also including those within the clouds and even those which strike the ground.
During earlier part of the year NASA has revealed that Lightening Imaging Sensor on-board is having one of its satellites detected an area in Venezuela experiences which were more lightening than elsewhere on the planet.
Various Thunderstorms Records:
Lake Maracaibo located Venezuela is getting about 297 thunderstorms every year and is experiencing up to 1.2 million lightening strikes every year.
Newer records is showing that there are other lightening hotspots around the world where these bolts of electrical energy can be behaving in strange ways.
Friction between the ice particles in clouds of thunderstorms can cause to build up electrostatic charge. Exactly what is triggering this includes a discharge which is still a mystery.
Most of the discharges travel from the cloud to the ground is following channels of the ionised air.
Some of the scientists is believing that these challenges are created by means of collision of high energy cosmic rays or neutrinos from deep space with the atmosphere of earth.
Lightning bolts can also travel from cloud to cloud while creating a variety of different types such as street lightning.
It streaked from Tulsa which is near the Arkansas border which is near to the Oklahoma Panhandle. It is starting at an altitude of 6 miles and has reached the ground in quite number of places.
Flash itself is lasting a little over five seconds. Even scientists are saying that length of the strike could be change to think about the safety during storms.
Views of Researchers:
Timothy Lang which is a researcher from NASA’s Marshall Space Flight Centre in Huntsville, Alabama says, “The lightning can start tens or hundreds of miles away and then come back to where you are.
You have to be careful of where the lightning is coming to ground, even though the storm is past.”
Randy Cerveny who is WMO’s chief rapporteur of climate and weather extremes adding to the same says, “The end result reinforces critical safety information regarding lightening, specifically that lightning flashes can travel huge distances from their parent thunderstorms.”
Lightening bolt in France has occurred on 30th August 2012 over Provence Alps Cote d’Azur. Bolt apparently doubled back over itself. Both of the bolts has recorded in the Bulletin of the American Meteorological Society.
