Due to the interference of the airflow on a high wing aircraft between the fuselage and the wings, the lateral stability of the aircraft in a gusty wind situation will cause
- the upper wing to increase its lift.
- the upper wing to decrease its lift.
- the lower wing to decrease its lift.
Explanation from PART66Online
On a high-wing aircraft the fuselage interferes with the airflow over the upper, raised wing during a disturbance, reducing its lift relative to the lower wing. This lift difference creates a restoring rolling moment that returns the aircraft toward level, contributing to the strong lateral stability of high-wing layouts.

If the aircraft is upset in roll (laterally), the lower wing is presented to the airflow fully whereas the upper wing is partially obstructed by the fuselage and therefore generates less lift.
