Typhoon is a tropical cyclone, and the airflow in the center of the cyclone is rising. Why is there a downward airflow in the typhoon eye area?

This phenomenon is caused by centrifugal force.

A tropical cyclone is a low-pressure vortex. Air flows from all directions to the middle and then rises. However, due to the centrifugal force generated by air rotation, the airflow in the central part of tropical cyclone-typhoon eye area can not enter and is also thrown out of the central area by centrifugal force. In this way, the air lacking in typhoon eyes needs to be replenished from high altitude, so there is a downward airflow.
