Recently, Ukrainian polar explorers have repeatedly observed a unique phenomenon above the Akademik Vernadsky station – nacreous clouds. Scientists joke that seeing them is “the dream of all meteorologists,” the report said.
According to meteorologist Anzhelika Hanchuk, this phenomenon is formed at a high altitude for clouds – 15-30 kilometers.
“But how can a cloud form at those altitudes where it is usually completely dry? When here, near the ground, the air flow encounters an obstacle in the form of mountains, a wave is formed on the leeward side of the mountain. other clouds of the stratosphere. At low temperatures and high wind speeds, moisture can exist only in the form of the smallest droplets of supercooled water and ice crystals, “said the meteorologist.
She added that due to this there is a pearly beauty of such clouds. At sunset, light is reflected from these crystals in the clouds in such a way that there is an optical effect of iridescence. He just “paints” the clouds in different colors.
