Weather Tidbits: Advection Fog
This Weather Tidbits explores how advection fog is different than radiation fog. Two factors are involved when advection fog forms which are a cold land and warm, moist air. The warm, moist air moves over the cold ground; it is cooled to saturation, this typically occurs with a warm front passage in winter. Advection fog differs from radiation fog by forming during the day. Sea fog is always advection fog; where warm air from a warm current drifts over a cold current and condensation occurs which occurs off the Pacific Coast of North America.
