A question about the eye of the typhoon

The vertical movement of the airflow in the eye of the typhoon is sinking.

This is because the high-speed rotating strong wind makes the air near the typhoon eye thrown to the periphery by centrifugal force, and the empty space is supplemented by high-altitude air, resulting in the vertical movement and sinking of the airflow. The air flow in the eye of typhoon sinks, the sky is clear, and there is no cloud or rain in Wan Li.
