According to the Sydney Morning Herald, the smoke from the Australian bushfire is so severe that it is expected to circle the earth and return to the country`s sky from the west.

NASA said this week that smoke had billowed into the lower stratosphere, reaching 17.7 kilometers above sea level.

Just then, Australia`s major cities are still battling the low air quality caused by bushfire smoke. Wangaratta was the world`s third-worst city for air quality on Tuesday morning, with the Melbourne suburb of Doncaster moving from fifth to sixth. According to the World Air Quality Index, India`s city of Singrauli is the worst.

Brett Sutton, Victoria`s chief health officer, said Melbourne`s air quality was the worst in the world overnight. He expects the weather to improve during the day on Tuesday.

"The smog is expected to form at least one complete ring around the world, returning to Australia again," NASA said. ".

"Over the past week, NASA satellites have observed the Australian fire and the large amount of smoke from its subsequent eastward diffusion into the atmosphere. "

This year`s fire season has seen more than 5.2 million hectares burned in NSW and 1.3 million in Victoria.

Smog has had a huge impact on nearby New Zealand, which has experienced serious air quality problems and darkening the colour of mountain snow.

NASA satellites have shown that smoke has spread more than 6,500 kilometres out of Australia, some arriving in Chile, where there are reportedly hazy skies and colorful sunsets.

NASA also referred to storms caused by bushfires in Australia, or cumulonimbus events that intensified fires this week as "rare."

Mike Fromm, of NASA`s Naval Research Laboratory, said it was "Australia`s most extreme cumulonimbus storm outbreak" by the agency`s standards....

When the moisture in the smoke that gathers in the upper air of the cold air produces a cloud, and then the cloud produces lightning, it produces a focal rain cloud.

Chip Trepte, a project scientist at CALIPSO, a research institute at NASA`s Langley Research Center, said:" A large number of high-temperature cumulus cloud events are relatively rare - especially on this scale. "

Using satellite data to track smoke, satellite data are used to establish the ultraviolet aerosol index.

According to Colin Seftor, a research scientist at NASA`s Goddard, the UV Index In particular suitable for tracking the smoke generated by cumulonimbus events because the higher the smoke column, the larger the aerosol index value.

"The aerosol index from some high-temperature cumulonimbus events in Australia has reached its maximum ever," he said. ".
