Which type of fog is also known as sea smoke?

Steam fog, also known as sea smoke, forms when cold air moves over warmer water, causing evaporation. As the warmer water vapor rises and encounters the colder air, it condenses into tiny droplets, creating fog. This phenomenon is most commonly observed over lakes, rivers, or oceans, particularly during the winter months when the temperature difference between the air and water is significant. The visibility can be reduced dramatically due to this thick layer of water droplets hanging close to the surface, resembling smoke hovering over the water. This is why it is referred to as "sea smoke" when it occurs over the sea, highlighting the visual similarity to the appearance of smoke in the air.

In contrast, ice fog forms in extremely cold temperatures where water vapor freezes into ice crystals, radiation fog forms through the cooling of the ground during clear nights, and advection fog occurs when warm, moist air moves over cooler surfaces, causing condensation. Each of these types involves different processes and conditions for formation, which is what distinguishes them from steam fog.
