冷夏에 대한 氣候學的 硏究 - 嶺東ㆍ東海沿岸地方을 中心으로

Abstract

The Anomalies of July-August average temperature and the surface and upper layer data were analyzed to clarify characteristics on cool summer occurred in Yungdong and East Sea coastal area.

The summer period since 1910s was roughly devided into three types; namely cool summer period for 1910s and 1950s, hot summer were frequently alternated.

The low temperature areas at the time of cool summer were a part of zonal low temperature area in the midlatitude of East Asia.

During the cool summer, the Okhotsk High and the surface pressure of western Pacific were intensified, while the North Pacific High was weakened. Under these situation, the Changma front was suppressed to the south and stagnated over the far south area, consequently Changma period was extended.

As the Okhotsk High has been intensified, the cool air was outflowed in the tongue-like forms from the high pressure area over East Sea to Yungdong coastal area, and surface wind, mainly, northeaster, seemed to the same properties as Yamase in northern Japan prevailed in the East Sea coastal area.
