Judo, which has become popular in more than 200 countries and regions, has developed while merging with both national and ethnic sports. Among them, chidaoba practiced in Georgia is a remarkable example of anethnic martial art. However, no literature in Japan has yet described the technical form and historical background of chidaoba in detail. Therefore, the purpose of the present study was to clarify the essence of chidaoba by considering its historical and cultural background. The author has mastered basic Russian language skills and performed a search for academic essays and websites using keywords such as chidaoba or Georgia and ethnic martial arts in Russian. To ensure accurate translation from Russian into Japanese, the text was checked by several Japanese with native-level Russian language skills. Chidaoba matches were held on Christian holidays such as Saint George’s Day and the Svetitskhoveli Cathedral Holiday. Thus, chidaoba took root in cities and rural areas as an irreplaceable festival event. Later, when the Christian church banned some forms of ethnic entertainment and physical exercise, only chidaoba was exempt. Before a match, competitors were obliged to perform the traditional dance, kartuli or palavnuri. In chidaoba, any type of grasping from the waist and upper body is allowed, while grasping below the waist is prohibited. There are a wide variety of techniques in chidaoba, such as throwing from close contact, foot throwing, foot sweeps, reaps, and hooks. Due to the diversity of Georgians, ethnic groups vary from region to region. Moreover, there are several different forms of martial arts in the mountainous areas of Georgia, which are very different from chidaoba. In 2018, chidaoba was registered as an Intangible Cultural Asset. The results of this research should serve as a basic material for clarifying the outline of the Georgian ethnic martia art chidaoba.

大雨の解析にアンサンブル予報解析システムを用いると,アンサンブルによる複数の再現結果から大雨と環境との相関や感度など,決定論的予測では得られない多くの知見が得られると期待できる.本論文では,広島県南部で観測史上1位を記録した2014年8月19~20日の大雨についてアンサンブル予報解析システムを用いて大雨の再現を行った.得られた20メンバーの中から再現性の良いメンバーと悪いメンバーとを選び比較することで,下層インフローなどの環境と降水量の環境を調べた.その結果,①湿った南風域が伊予灘から広島県南部に到達して大雨になった,②南風が強い場合に明瞭な線状降水帯が形成され降水量も大きくなった,③ストームに相対的なヘリシティーが大きい時に広島湾の下層水蒸気輸送量と広島の雨水混合比との間に正の相関がみられ,移流時間を考慮するとさらに相関が強くなる,④この事例では不安定指数(CAPEなど)と降水量の相関は弱く位置や時刻で大きく変動するため,不安定指数のみを用いた大雨の議論は注意が必要であることが分かった.
