On the Formation of Fog associated with the Advection of the Air

[摘要] Sea Fogs on the shore of Hokkaido and Kurile Islands are supposed to be associated with warm air which steams northward over the cold ocean current. Authors intended to ascertain this assumption by constructing the trajectory diagram of the air on the weather chart. The result shows that the assumption is correct and when the air travels over the ocean, east to Honshu, Northern Fogs are formed, and when it travels over Honshu or Japan Sea, fogs are seldom observed. However there were exceptions according as the position and the time of observation, so we also inquired into the circumstances of these cases.
