5 Really Weird Phenomena That Only Happen in Winter
Rare Thundersnow Phenomenon
We all know that thunder happens in summer; however, if you've ever experienced it in winter while it was snowing, you probably wondered what on earth was going on. What you heard was not regular thunder but thundersnow. Thundersnow takes place on occasions when clouds from a snow storm start forming vertically very fast. In such cases, a strong electrical charge is created which, combined with turrets formed at the highest point of a vertical cloud can cause the thundersnow phenomenon.
Light Pillar Phenomenon
Light pillars appear during extremely still and chilly nights when small ice crystals that are usually found in the sky can be formed slightly above the ground and thus pile onto one another. The crystals mirror the light coming from lamp posts or cars and give away the impression that a strange and beautiful pillar is formed, which can seem like something extraterrestrial.
Despite their name, cryovolcanoes, i.e. ice volcanoes do not erupt lava, ashes, and hot gases or anything similar. Ice volcanoes got their name due to the fact that ice sometimes tends to act just like a volcano. Namely, in case the ice that is found on shorelines is not strong enough, a slightly stronger wave may lead to an eruption. Unlike regular volcanoes, cryovolcanoes erupt iced gases found in water, methane or ammonia.
