Jim Collier > These are literal "rivers" of fog. They flow fast, I'd estimate between 5 and 15 mph. They follow the shortest, quickest path inland and downward. They are not just cool as you might expect, but downright frigid. Especially later at night (of course when they are harder to photograph and experience in general), it will be 70 degrees, dry, and calm literally ten feet from a fog river; then 20 degrees colder (and very windy and damp) once you walk into it.The rivers evaporate at their leading edge as they peter out in the face of warmer air, continually flowing into oblivion like some kind of continuous flowing lemming colony. However the process of evaporation of the minute water droplets into vapor cools the air even more, thus the fog slowly paves its own way ever forward. (That's my theory at least.) Eventually these rivers engulf Sausalito most summer nights. The rivers seem to slow and diffuse dramatically over towns and cities, so the best place to experience the freakiness of it is well inside the Golden Gate National Recreation Area.The summer fog is formed by cold air being pulled off from the ocean (which in turn is cooled by upwelling deepwater currents that happen in the summer). It is sucked in overland by warm rising air well inland. Since it is so much colder than the surrounding air, the condensation is extreme and resulting fog is really visually dense. Also as a result of the extreme gradient, it hugs the ground tightly. As a result of that, Sausalito has markedly different "microclimates", where the fog will sock in one valley but not the next, resulting in one being consistently cold, wet, and windy--while the valley one quarter mile away will be a warm, dry paradise.The fog stops when it hits larger impenetrable masses of warm air, or when the next day's sun burns it off. Winter fog is much different: larger-scale and more cloud-like. It doesn't flow in rivers like summer fog.
