A waterspout is a tornado that occasionally appears on warm water. In essence, this is a vortex, and the air rotates rapidly around the axis of the tornado. Attracted by the extremely low air pressure in the center of the tornado, the water flow is sucked into the bottom of the vortex and then becomes a vortex around the axis. Many waterspouts are formed far away from the thunderstorm system, even in fairly clear weather. The waterspout can be quite transparent. When it is just formed, it will only be noticed through its unusual pattern on the water.
As for whether the water will fall, it will definitely. When the intensity of the vortex weakens, including the energy release of friction, etc., there is no such strong pressure difference and upward movement, and water will fall. For example, the story of "fish falling from the sky". .
