Advection fog
Vancouver has been covered with fog for three days. It was so thick that the Vancouver international airport was temporarily closed yesterday. Of course my flight lesson was canceled. As I have just learned in the ground class, this type of fog is called "advection fog," which is formed when warm and dump air-mass comes over the cold sea or land surface. The warm and dump air-mass contains lots of water vapor and can be easily saturated when touching cold surface forming a fog. It won't go away until wind blows it away because the condition of air-mass is very stable; the lower the colder and heavier, and the higher the warmer and lighter. I feel this fog is getting thicker day by day. I couldn't see even the Burrard bridge from my room. I wonder when I can fly next.
