Lifting surfaces such as wings can also generate condensation in humid air. The physical reason should be obvious to anyone familiar with aerodynamics. The lift is due a relatively low presure on one side of the wing and relatively high pressure on the other side. If the pressure on the suction side is low enough, the temperature of the water vapor may be low enough to cause condensation.
Such condensation is usually seen during situations requiring large lift, e.g., during high-g manuevers or during landings or take-offs. Clouds will then form on the upper surfaces of the wing. Because wingtip vortices are also caused by lift, their strength will also normally be large under these conditions. You will frequently see both types of condensation simultaneously.
