Rain passes through the mountain village. The first two sentences describe the characteristics of the mountain village scene.

The raindrops continue to evaporate and disappear during the falling process, forming striped pendants at the bottom of the cloud. It got its name because of the striped raindrops or ice crystals hanging at the bottom of the clouds, floating with the clouds and resembling flags. However, because the air is dry, rain and snow evaporate in the air before they hit the ground, resulting in aerial precipitation. There are two types: rain flags and snow flags. Rain streamers mostly appear under cumulonimbus, nimbostratus, altocumulus and stratocumulus clouds; snow streamers mostly appear under cirrus clouds.

Rain flags around the world

Wyoming, USA

The strange shape of the rain flags in Wyoming, USA, has attracted people's attention. This photo was taken in In Wyoming, USA, it looks like this mushroom cloud has been cut off in the middle. Of course this is not a real mushroom cloud!

Liverpool, England

This photo was taken in Liverpool, England. The rain streamers in the sunset are even more magnificent. Due to the action of the wind, the delicate texture of the rain streamers has been bent, looking like orange flowers under the reflection of the sun. Rain streamers are often called "accessory clouds" because they usually exist attached to other clouds, such as cumulus clouds, altocumulus clouds, and turbostratus clouds. These clouds form the head of the rain streamer "jellyfish."

German Alps

This photo of rain streamers was taken in the Alps in Germany. The dry, high temperatures here are thought to be a key reason for this interesting formation, but this phenomenon can also have some undesirable side effects. For example, the cooling caused by evaporation will form some low-temperature air masses. These air masses sink in the air, which can be very dangerous for in-flight flights. However, it is still safe to view these rain flags from the ground.

Arizona, USA

This photo was taken in Tucson, Arizona, USA. Rain streamers are very common in desert areas.

Texas, USA

This photo was taken by photographer Paul Garland in El Paso, Texas, USA ) photographed. In the photo you can clearly see the wind picking up from the ground up, bending the rain flags from mid-air. Humidity is low in El Paso, and little precipitation falls to the ground, Garland said.

Tucson, Arizona

This is a highway near Tucson, Arizona, USA. There is a rain streamer structure just above it. It looks like a huge UFO. Every year, many people claim that they have just witnessed a UFO after seeing the rain flags.

Sweden

This is Sweden. These "jellyfish" don't seem to be as anxious as other places. They float leisurely in the blue ocean. Nature is truly a great artist.
