Laminar, Turbulent & Vorticesed Airflow - F1 Technical Terms

Laminar airflow is what you would consider to be uninterrupted airflow, whereas Turbulent airflow is the breakdown of this pattern into an erratic state.

Turbulent flow ensues when either laminar flow comes up against a blunt object that destabilizes the airflow or is converted to turbulent flow when covering a sustained distance over a body (see Boundary Layer build up)

The shaping of bodywork can be used to roll up airflow into a Vortex, the same occurs when two pressure gradients combine (ie Low Pressure and High Pressure meeting at the end joint of a Wing).  Vortices can be utilised to enforce certain airflow patterns and are a critical factor when designing an F1 car.
