On the Formation of SK-type Clouds

[摘要] During the cold season the directions of clouds of the lowest stratum are often opposite to that of the surface currents.On such an occasion as the direction of the surface wind is NW and that of cloud SE, an unexpected weather appears. This occurs when Kwanto districts just entered into the region of high pressure, and then warm air on the ocean and the cold on the land are clearly defined. The condition that the upper currents are opposite to the lower depends entirely upon the proximate existence of two air masses stated above.Warm and wet air advances towards the colder land and gradually becomes cool. The stratified cloud accompanied by drizzle thus arises.
