High school geography: Why is the typhoon eye sunny?

This profile shows how a low pressure area on the ground produces a high pressure area vertically above it, which is the atmospheric circulation needed for typhoon maintenance. Warm and humid air is concentrated on the sea, and the atmosphere rotates in the rising process, forming dense cloud belts, which can cause showers. Some dry updrafts are forced into the rotating airflow, forming a calm typhoon eye. When the updraft rises to a certain height, it begins to gather and produce high pressure, and the atmosphere turns from the high pressure center and sinks outside the storm wall.
