As many as 21 people died in Zimbabwe in 1975 when rushed for safety to a hut that was hit by the bolt. Imagine a lightning bolt igniting in a giant thunderstorm over San Diego and then shooting north almost all the way to San Francisco. Where Was the Birthplace of Modern Humans? | The Newshour Debate, PM Modi takes stocks of COVID-19 vaccine; Will appeal for talks end takrar? (Source: World Meteorological Organization), The two record-setting lightning flashes, one over Brazil that's the longest ever documented, and another over Argentina that persisted longer than any observed before. The earlier record holder for the longest duration of a single lightning flash was 7.74 seconds, which was measured on August 30, 2012, in southern France, WMO said. What's It Like to Simulate the Next Cascades Volcanic Eruption? The lightning mapper aboard GOES-16 offers an unmatched opportunity to monitor two hotspots for the development of Mesoscale Convective Systems: the Great Plains in North America, and the La Plata basin in South America.

The flash lasted for a full 16.73 seconds. Photographer: Sean Waugh NOAA/NSSL. The largest lightning discharge in recorded history occurred on Oct. 31, 2018, in southern Brazil, although the flash stretched from eastern Argentina all the way to the Atlantic. WMO has recognized 2 new world records for a single #lightning #megaflash Another new world record was set for the duration of a lightning flash, with a single flash, that developed continuously over north Argentina on March 4, 2019, WMO's committee of experts on weather and climate extremes said. The first of a new generation, GOES-16 carries an instrument that continuously maps all lightning activity across North and South America. They often occur on the Great Plains of the USA and can spawn tornadoes. The quirky weather records are stored in the WMO Archive of Weather and Climate Extremes. It occurs over and around Lake Maracaibo, typically over a bog area formed where the Catatumbo River flows into the lake. Another record is for an indirect strike when lightning struck a set of oil tanks in Egypt's Dronka in 1994 causing burning oil to flood in the town. WMO’s Committee on Weather and Climate Extremes also announced a new record for longest duration flash: 16.73 seconds from a flash that developed over northern Argentina on March 4, 2019. | The Urban Debate, Know about the average calories and nutrition facts in dosa, Pune: Oxford University vaccine 90% effective, Government Job Recruitment Exam racket busted, Pune: No social distancing during protests, Bakhtawar Bhutto gets engaged to Mahmood Chaudhary [PICS], Shillong Teer 27.11.2020 1st and 2nd round result announced, Amrik Sukhdev dhaba in Murthal serves free food to farmers, Shillong Teer 28.11.2020 results announced, World's most expensive handbag unveiled. DOUBLE the previous records One of them is for the most people killed by a single direct strike of lightning. "This makes the GOES-16 GLM an excellent platform for documenting extreme lightning," scientists concluded in a recent paper on the record-setting flashes. 74 seconds over France in 2012 — right out of the, well, cloud... "These are extraordinary records from single lightning flash events," says the WMO's Randall Cerveny, quoted in a WMO release about the episodes. This far surpasses the previous record of 199.5 miles, set by a flash on June 20, 2007 over Oklahoma. | The Newshour Debate, KT Rama Rao on GHCP, illegal encroachments, AIMIM-TRS friendship & more | Frankly Speaking, Will the demands of Annadatas be fulfilled? In each case, they were the product of a gigantic collection of thunderstorms acting as a single system — a phenomenon meteorologists call a "Mesoscale Convective System," or MCS. 2011 Supercells are powerful thunderstorms which form around a mesocyclone, a deep, rotating updraft. At up to several kilometres across, they can last several hours, making them the longest-lasting and largest of all thunderstorms. These record-setting bolts were not spawned by every day thunderstorms, the kind of compact storms that flash frequently and thereby deplete the electrical charges that give rise to lightning. If that seems impossible, consider that just such a prodigious lightning flash has now been confirmed — not in SoCal but in South America. (Credit: WMO). The new record-setters came under the discerning eye of what was then a newish weather satellite, GOES-16. Megaflashes "are defined as horizontal mesoscale lightning discharges that reach hundreds of kilometres in length," Michael J Peterson, of the Space and Remote Sensing Group of Los Alamos National Laboratory in the US, said in the statement.

How Old Is the Oldest Stuff in the Solar System? The UN agency has revealed similar weather-related milestones in the past, such as in 2016 a record wave measurement of a behemoth that towered 19 metres (62.3 feet) above the North Atlantic. The massive overhanging anvils and raining regions of these monsters have large electrified clouds with low flash rates, which allows charges to build up significantly. As many as 469 people had died in the incident.

It happened on Halloween of 2018, when a system of massive thunderstorms boiled up over southern Brazil and spawned a single bolt stretching across 440 miles, from the Atlantic coast all the way into Argentina. The new megaflash records have been verified with a new satellite lightning imagery technology. It originates from a mass of storm clouds at a height of more than 1 km, and occurs during 140 to 160 nights a year, 10 hours per day and up to 280 times per hour.
