When this pressure passes by, the compressed air suddenly expands and cools. If there is enough water vapor in the air and it condenses as it cools, the condensed water shows up as water droplets (cloud). This is seen even in subsonic situations when the air is humid enough. You can probably see a bunch of these videos on youtube where people take movies of takeoffs and landings.<br><b>References : </b><br> The shock wave is a sudden build up of pressure in the air.
