Advection fog is most likely to form when - ATPL

Cold air is forced over higher ground and further adiabatic cooling occurs

A mild moist airstream flows over snow covered ground and the wind speed is less than 10 kt

Warm maritime air flows over a relatively warmer surface and the wind speed is greater than 15 kt
