The plume thought to have been from Pinatubo was, it turns out, from a pyrocumulonimbus storm in Canada. Three "mystery cloud phenomena" were cited as examples that were actually the result of pyrocumulonimbus storms, including one initially attributed to the 1991 eruption of Mount Pinatubo in the Philippines. The paper reevaluates previous data to conclude that many stratospheric pollution events erroneously have been attributed to particles from volcanic eruptions.

Yue is one of eight authors of a paper on pyrocumulonimbus in the September 2010 Bulletin of the American Meteorological Society (BAMS) titled "The Untold Story of Pyrocumulonimbus."Ī pyrocumulonimbus cloud towers over thick smoke from fires burning near Canberra, Australia, in 2003. Yue, an atmospheric scientist at NASA Langley Research Center in Hampton, Va. "An individual pyroCb can inject particles into the lower stratosphere as high as 10 miles," says Dr. They also suggest pyroCbs happen more often than thought, and say they're responsible for a huge volume of pollutants trapped in the upper atmosphere. Researchers believe these intense storms may be the source of what previously was believed to have been volcanic particles in the stratosphere. And in the process, "pyroCb" storms funnel their smoke like a chimney into Earth's stratosphere, with lingering ill effects.

Pollutants from these storms are funneled into the stratosphere. The policeman said that the kiln was now being checked in order to ensure it is safe for future cremations.Pyrocumulonimbus is the fire-breathing dragon of clouds.Ī pyrocumulonimbus storm combines smoke and fire with the features of a violent thunderstorm. Police said that due to the circumstances of the death, locals believe that the priest's body should not be cremated and his remains have been sent to his family for burial. The priest was very experienced and had performed thousands of cremations," he added. "The cause of the explosion is not known. "The door hit him on the forehead causing him to die instantly due to the serious injuries." "When the priest lit the corpse, the crematorium furnace exploded and the large steel door was blown off from the force," Lino said. Soeun Had Been Burning Corpses for Over 4 Decadesĭeputy Police Chief Liutenant Colonel Seng Lino said that the priest had been burning corpses for more than 40 years and the incident happened while he set the corpse of the youth on fire with wood and 30 litres of gasoline. They said that this was the first known accident of this kind at a funeral site. Police investigated the death at the pagoda in the Cheung Prey district and ruled the priest's death as accidental.
