    1976年8月18日から20日までの3日間,長野県菅平の大松山(1,648.7m)の北東向斜面上で観測を行なった.地上1.3mと0.3mの気温差を逆転度(正の場合が逆転)と定め,斜面に沿う逆転度の分布の時間的推移から,大松山の斜面上における日没前後の冷気流の発現域および流出域を究明することを試みた.その結果,1976年8月20日17時30分から20時00分までの観測時間中,測点2 (1,370m)付近は常に逆転度が負であったが,その斜面下部にあたる測点3 (1,320m) から測点5 (1,275m) 付近に及ぶ範囲では,+0.5°C以上の大きな逆転度が,18時55分から19時27分頃にかけてと,19時32分から19時50分頃にかけての2度形成された.これらの時間帯について冷気流の発現域にあたるか,流出域にあたるか検討を加えた結果,19時00分から19時20分頃にかけての測点3付近は発現域,19時14分から19時27分頃にかけての測点5付近は流出域と判断された.

    It has often been said that during the period of rapid economic growth of Japan there is a noticeable shortage of toji, who are the leaders of dekasegi-sha (seasonal labor migrants), in sake-brewing industry. Dekasegi-sha in the sake brewing industry, led by toji, go to sake-brewing regions from rural areas.
    There are few studies on the recent changes in the patterns of dekasegi-sha in the sake-brewing industry, and on the relationship between the social conditions in the rural areas from which dekasegi-sha come and the recent trends in the sake-brewing industry.
    The purposes of this paper are to discuss the patterns of dekasegi-sha in the sake-brewing industry, to find important factors of the changes in the patterns, and to find the structure of supply and demand of dekasegi-sha in the sake-brewing industry.
    The findings are as follows:
    1. The main streams of dekasegi-sha in the sake-brewing industry were from rural areas in the Setouchi and Hokuriku regions to the sake brewing districts in the Kinki, Chugoku, and Kanto regions. From 1927 to 1973, the number of dekasegi-sha in the sake-brewing industry from Okayama, Yamaguchi, Hyogo, Aichi, Ishikawa, and Fukui prefectures decreased. During the same period, the prefectures that increased the number of dekasegi-sha in the sake-brewing industry were Iwate, Akita, Nagano, Yamagata, Fukushima, and Saga prefectures (Fig. 1). The change in the distribution of toji revealed three types: (1) increasing type (Iwate and Akita prefectures), (2) decreasing type (Niigata, Hyogo, and Ishikawa prefectures), and (3) near-extinguished type (Kyoto and Shizuoka prefectures) (Fig. 2).
    2. The recent reorganization in the sake-brewing industry reduced the need of dekasegi-sha. The increasing employment opportunities for farmers who seek part-time jobs reduced the number of dekasegi-sha in the sake-brewing industry. The toji groups from Iwate prefecture are moving into the Kanto and Chubu regions, and the toji groups from Niigata prefecture are moving into the Chubu regions.
