96-A night in January has been cold and clear. In the forenoon of the next day an airfield is in IMC due to fog which extends to a height of 700 ft. A heavily laden aircraft departs and, when breaking through the top of the fog, experiences temporary bumpiness and a sudden decrease in climb rate.
Mark the answer that states the most probable reason for the altered aircraft performance.

050 16751 Flight Hazards

The aircraft is under influence of a mountain breeze (descending air from the surrounding hills due to the incident sunshine). The aircraft suffers reduced lift and thrust due to a temperature inversion at the top of the fog. The additional weight gained by water which has been gathered on wings and fuselage during flight through the fog reduces the lift. The water which has been gathered during flight through the fog modifies the aerodynamic properties of the aircraft, thus reducing lift.
