Mind-Blowing Cloud Formations You Probably Haven't Seen Before
Various cloud formations might be one of the most beautiful and romantic sights in nature. Still, these masses of liquid droplets is also a complex and scientifically interesting natural phenomenon. The interesting fact is that regardless of the shape and the looks of the cloud, they’re all made of the same thing – condensed water or ice. When the sun heats the ground, warm air starts to evaporate and rise towards the sky. Once these water vapor particles cluster together, a cloud is formed.
Polar Stratospheric Cloud: Polar stratospheric clouds (PSCs), also known as nacreous clouds from nacre, or mother of pearl, due to their iridescence, are clouds in the winter polar stratosphere. PSCs are wave clouds. They are often found downwind of mountain ranges, which can induce gravity waves in the lower stratosphere. Their sheet-like forms slowly undulate and stretch as the waves evolve. The clouds can also be associated with very high surface winds, which may indicate the presence of, or induce, winds and waves in the stratosphere.
