Nancy LeGendre (Member 53,493) watched the Sun rise over a smoking sea to illuminate a bank of Stratocumulus off on the horizon. Sea smoke is not, of course, smoke but a form of fog that can develop when very cold air drifts over a warmer water surface. The surface warms the lowest of the cold air, encouraging it to rise in little swirling currents that carry some of its moisture up with them. As these little convection currents mix with the chilled air just above, the moisture condenses out as droplets, much like the steam that rises from your hot bathwater or your cup of coffee. Judging from the thick white frost covering the ground on this chilly morning in Gloucester, Massachusetts, US, it’s about time for a hot cup of morning coffee to start the day.
