What caused Hobart’s eerie Halloween sunset?

The skies over Hobart looked just as eerie as the streets during this Halloween, thanks to a combination of perfect light and spectacular cloud formations.

The incredible mix of bright orange and deep, dark purple was captured by photographers and trick or treaters out Sunday night.

Photographer Wayne Painter in Carlton, east of Hobart, took several photos with his camera pointed west, across Tiger Head Bay and toward the city.

The photos have attracted attention on the Facebook group Weather Obsessed and have so far been shared more than 2,500 times.

Glen Perrin, a forecaster at the Bureau of Meteorology, said the beautiful and enchanting stratification effect was caused by lens-shaped clouds.

“They’re certainly not uncommon, but what makes the pictures so spectacular, of course, is the sun angle at that point, and we get all the rich colors in the picture,” Perrin said.

The mountainous geography of Tasmania makes it particularly suitable for the formation of lenticular clouds.

“They tend to form when the wind passes over the high ground, and it becomes turbulent when it passes over the high ground,” Perrin said.

“This can produce a wave pattern in the current [of air]. “

Air condenses as it moves toward the top of the air wave, forming clouds. It then evaporates as it descends on the other side, resulting in the revealing crescent shapes in the sky.

It is the movement of the air around the cloud formations that gives them the hovering, eerie look that has sometimes been compared to alien spaceships.

For those who want to capture a similar snap, the Bureau of Meteorology says these types of clouds can form at any time of the day, at any time of the year without prior notice.

The best thing photographers can do is simply be prepared.

“It’s more a case of you having to be ready,” Mr Perrin said.

“Not only clouds, but we’ve also been getting the Northern Lights lately, so you should always be eager and always be ready to take that picture.”
