Separation Point: The point at which the air flow separates from the surface of a body. Series: The same as the mark of an aeroplane or aero-engine which identifies a particular type.
Up to the separation point, the difference between the static-pressure distribution for ideal fluid flow and real airflow is not very large but once separation occurs, the pressure field in greatly modified.
When the AOA of the wing increases the separation point moves forward and the streamlined airflow wil become turbulent and separates from the wing. This turbulent wake then meets the aft fuselage and tail section of the aircraft.
