What combination of atmospheric conditions is most favorable for the formation of Radiation Fog over land surfaces?

1. Strong surface winds (25+ knots) and overcast low cloud layer
2. Clear skies, high relative humidity, calm or light winds (2 to 5 knots), and nocturnal radiative cooling
3. Warm moist air blowing rapidly over cold ocean currents
4. Intense solar radiation heating dry air during afternoon hours
