Clouds or waterfall? This video of clouds floating through Aizawl is going viral

The viral clip shows clouds descending from a higher level to a lower one, with many saying it looked like a fluffy waterfall.

Watch the video here:

The stunning visual comes from a  phenomenon known as orographic clouds that are commonly known as “waterfall clouds”. These clouds are generally associated with a moist airflow over mountainous areas.

It usually occurs when stable air encounters a mountain, and is lifted upward, cooling as it rises. Water vapour in the moist air could condense, making it visible as a cloud. So when orographic clouds flow down from the tops of mountains, it often looks like a waterfall.

Here’s another video of the same phenomenon that was seen at China’s Mount Lu in 2017, which had also taken social media by storm at the time.
