Is the type of fog we are experiencing in the North Midlands radiation fog? Just been reading about fog and the current weather conditions.


There are two kinds of fog, radiation and advection.


What about sea fog?






Most sea fog is advection fog. Warm moist air runs over cool sea whose

surface temperature is below the dewpoint temperature of the air.




Thanks for that, but it seems not to explain the sharp edges that North Sea fog has on occasion, or the isolated but regular days when radiation fog over south Dorset drifts out over Lyme Bay and not only becomes sea fog but expands its area when clear of the coast.
