Rare waterspout-like vortex observed over Brahmaputra in Assam
A rare weather phenomenon resembling a waterspout was observed over the Brahmaputra in Assam’s Barpeta district. A waterspout is a rotating column of air and mist over a water body, usually less intense, lasting ~5 minutes (up to 10), averaging ~165 feet in diameter with winds around 100 km/h. It forms with high humidity and warm water relative to overlying air. Types are tornadic (thunderstorm-linked, develops downward) and fair-weather (calmer cumulus base, develops upward, little movement).
