Fog is nothing but cloud on the ground.It forms in the same way as a cloud forms.In short, fog comes from the condensation of water vapour near the ground.Calm wind,ground inversion and clear skies on the previous night help the formation of fog particularly in the early morning.
Another major type of fog is advection fog. This type of fog is caused the movement of moist warm over a cool surface like the ocean. Advection fog is common in San Francisco and it forms in the summer when warm air from the Central Valley moves out of the valley at night and over the cooler air over the San Francisco Bay.
