I don’t claim to be an expert on fog, smoke or steam. My prior post called “Fog on Penobscott Bay” was about a photo I took one early morning in August. I did a bit of research online and found that there are several kinds of fog. My conclusion based on the definitions given, was that the summer fog we experience along the Maine coast is “advection fog”. It requires warm air over cold water.Well, today I explored online the concept of “sea smoke”. I had seen a number of photos of sea smoke, though mostly they were taken along the Maine coast in the winter. Nevertheless, I was pretty sure that is what I saw one cold morning last October.
Sea smoke can occur when cold air moves over warm water. (It seems this is the opposite of the conditions that lead to fog.) I think this is what happened in the image shown below.
This image was taken on a cold October morning. I am presuming that the air temperature was colder than the water surface temperature. It was about 6:45 a.m. and the sun had just begun to show itself. I’m thinking this created the required layer of moisture-saturated air above the water that then cools and condenses.
Of course I could be wrong about this, but it nevertheless was a pretty picture.
