Qingdao residential area is covered by icicles. What caused it?

When the weather is very cold, many places are frozen, and there are even icicles on the eaves. If there are icicles on the eaves, if others don't clean them up, they will easily fall downstairs and hit others after melting, which will have a certain impact on the safety of others.

This kind of scene is hard to see in ordinary life, but it is very shocking for everyone to see such a spectacular scene now. This situation is brought to us by nature. If it wasn't very cold, there wouldn't be such icicles at all. Like nature, like waterfalls. Netizens have seen this video, and everyone didn't expect the icicle area.

But more people care about their water. If there is no hot water in winter, it is difficult for these residents to live. All these water pipes burst, and all the water leaked out of them, so the residents living in high places could not use water. This behavior is actually a property problem. Property management at that time did not do the corresponding governance, did not check the lack of water leakage, there will be such a water column. But if we only look at these waterfalls, it is really a beautiful scenery. These icicles must be cleaned up as soon as possible. Don't look good, just stay there. When the weather is warm, these icicles will melt from it and accidentally fall on other people's balconies, which will have certain influence, so it is best not to leave this scene all the time in the lives of those residents. Before that, icicles actually fell from above and hit pedestrians' heads, causing pedestrians to die. In fact, these situations can be avoided. Don't blindly appreciate the scene and cause your own accidents.

In fact, the formation of accumulated ice includes two state changes: solidification and tuff, but solidification is the main one. Just like the formation of rime, it has both solidification and sublimation. Condensation mainly refers to the following phenomena: rainwater vapor liquefies into small water droplets or ice crystals melt into small water droplets and fall to the ground to become rainwater. Freezing rain falls on trees and wires whose surface temperature is below freezing point, and crystal clear ice immediately forms around them. At this time, raindrops keep falling on the surface of frozen objects and slowly droop to form icicles, some of which are called ice hangings.
