Spotters will often see engines fogging up inside an engine at high power. The same reason is causing these clouds to cover the wings of this departing 777. Airflow over the top of a wing travels a longer distance than the airflow under a wing because of the shape of the wing. The airflow on top thus travels faster than the air on the bottom. When air goes faster, it's pressure drops. This low pressure on top is what cause the wing to be sucked upwards, i.e. lift. Low pressure also drops the temperature of the air which in turn causes the humidity to increase, as cool air cannot carry as much moisture as warm air. When the air cannot carry any more moisture, 100% humidity is reached and clouds are formed, in this case, right over the wing!
