Waterspout in Vizhinjam
A waterspout phenomenon was observed in Vizhinjam, Thiruvananthapuram on Wednesday. A waterspout is a rotating column of air that occurs over a body of water, usually appearing as a funnel-shaped cloud in contact with the water and a cumuliform cloud. Fishermen who spotted the air column in the sea recorded it on their phones. See video.

During this phenomenon, a cloud sheet resembling lightning and a fountain descends into the sea from the dark clouds in the sky, causing the water to churn and form a vortex. Water rises in a funnel shape in several parts of the sea. The sudden pressure difference between the clouds is what triggers the waterspout phenomenon.
