Show Know The Weather What is fog? Is it really a cloud on the surface of the earth? YES, fog is nothing more, than a cloud. All clouds are formed when some kind of cooling process, lowers the moisture and becomes visible particles-thus a cloud. This process can occur in several different ways and under different circumstances. circums-tances. In the fall, the fog is often seen in most parts of the country (the west coast experiences much fog in winter). FOGS ARE usually caused when the earth (heated during dur-ing the summer) loses its heat into the cooler night air. As the warmer air from the earth's surface rises and is cooled, fog forms. Cold ground, in spring for example, can make its own fog when warm moist air blows over it by cooling the air to the cloud stage. FOG, THEN is nothing more than a land-locked cloud. |
