Abstract
A fog episode characterized by quasi-periodic oscillations in visibili ty is described. Gravity waves are also present, and frequencies at wh ich pressure and transparency fluctuate are compared. The existence of intervals during which they are synchronized and the presence of stro ng winds aloft suggest that shear instabilities in the troposphere can influence the fog behaviour at ground.
