F-35
As compression ceases along the aircraft,the air behaves as any refrigerant,expanding,losing the heat of compression,falling below dew point to create the cloud as the water vapor condenses.
The same occurs inside the aircraft,as some air from the compressor section of the engine,as a working fluid, is run through an expansion valve,creating air conditioning for the pilot.

...that's also why such 'visible' effects only happen when RH% is high and temperatures are low to moderate...they don't appear under hot & dry conditions. |

Those pic's were taken by my active duty friend while in Germany. They had the F35 at an airshow. Between the wingtip vortices and the clouding effect they are really cool pic's.

It's interesting how the single phenomenon causes two different effects.
The blunt trauma of the bow wave[s] is circular, even though the cross-section of the aerobody is anything but, and dissipates immediately; while the wingtips induce vortexes that persist indefinitely.
