Abstract
In June, there is a marked zone of downward motion over the southern part of the Sea of Okhotsk, the maximum value of which reaches 10 (mb⋅12hr-1) at 850-mb. It is also apparent that a distinct belt of upward motion extends from the south of Japan eastwards along the latitude circle. Of considerable significance in the patterns of atmospheric heatsources in June is the existence of a broad zone of cooling over the southern part of the Sea of Okhotsk. The maximum value of this cooling at 850-mb is about 2 × 10-1 (cal gr-1 12 hr-1). Such distributions of mean vertical motions a nd heat-sources show good correspondence with common experience concerning Baiu, which is the rainy season in Japan.Keywords
