Black skies over Siberia: Sun disappears behind thick clouds in bizarre repeat of 2018 blackout – Giant sub-Arctic wildfires spewing enormous amounts of carbon monoxide
9 August 2019 (The Siberian Times) – Residents of sub-Arctic Verkhoyansk district of Yakutia woke up in complete darkness.
There was no trace of light until after 8am local time over the Verkhoyansk district in the north of Yakutia.
Almost exactly a year ago – in July 2018 – there was another pitch black morning over three major areas of Yakutia, Eveno-Bytantaisky, Zhigansky and the same Verkhoyansky district.
Darkness which had a yellow tinge lasted for over three hours and was followed by drop in air temperature.
The territory impacted by the gloom was larger than Italy.
It was a high amount of carbon monoxide in the air that sped up and intensified the process of clouds formation, said chief specialist of Fobos weather station Yevgeny Tishkovets.
This time weather experts thought the blackout was caused by smoke from wildfires mixing with heavy rain clouds, and they didn’t register change in temperature. […]
‘This situation can be compared to what is happening during cloud spiking which is done to cause rain. The cloud cover was as thick as it can possibly be, add to this the wildfires smoke and precipitation. This is still, of course, rather approximate and we need to analyse what happened in a lot more details’, he said on Yakutia-24 TV channel.
The Fobos weather centre shared two maps, one showing extremely high amounts of carbon monoxide (7,19mg/m3 while the allowed maximum is 5mg/m3) in the air, and another one confirming very high level of cloudiness.
Currently heaviest wildfires are in the south of Yakutia, with smoke moving north. [more]
