Formation of strange clouds on Antarctica

The special cold condition of the southernmost tip of the earth created a strange cloud in the sky, scientists said.

Meteorologist Renae Baker captured breathtaking images of nocturnal clouds like nacre, also known as polar stratospheric cloud, late last week at Australia's Mawson station on Antarctica.

These clouds appear only at very high latitudes at the ends of the earth, under conditions of temperatures less than -80 degrees Celsius. - 87 degrees C.

Looking like nacreous shells in the air, these clouds formed when the dusk of the sunset through ice crystals was blown along a strong stray wind, at a height of more than 9 km. ground.

"Amazingly, this high-altitude wind blows at a speed of nearly 230 km / hour , " Baker said.

Atmospheric scientists from Australia's Antarctic stratum Andrew Klekociuk said we rarely see these clouds, but they are still often created when the air blows through the polar peaks.

"You have to stand in place in the winter, and the sun must be right under the horizon so you can see them," he said.
