通过对AMeDAS获得的风资料的分析，揭示了大阪湾地区陆风、海风及其环境的总体情况。研究区由复杂的陆海结构和复杂的地形组成，包括平原、丘陵和山区。根据海风在研究区多个地点的行为，将海陆风分为五种类型。最常见的类型的特征如下。在大阪湾南岸，来自大阪湾的海风随时间变化为来自Kii海峡的海风。与此同时，沿着内陆海沿岸的海风包含了一个主要的东风成分。对于这种类型，进一步阐明了几个有趣的特征：(1)沿海海风和山区的谷风或上坡风同时爆发，特别是在中部地区东部；(2)来自泽藤内海的南风和来自日本海的北风在中部地区东部的山脊附近相遇；(3)来自周围海域的辐合海风交替形成来自旭岛基伊海峡的均匀南风。(4)Kii海峡和大阪湾沿岸偏南海风持续到下午晚些时候。对海风成熟阶段的其他类型进行了讨论，并与上述类型进行了比较。分析了海陆风的发生与一般气象条件的关系。
The general aspects of land and sea breezes in the Osaka Bay area and its environment are revealed from an analysis of the wind data obtained by the AMeDAS. The study area consists of a complex land-sea configuration and a complex topography which includes plains, hilly terrain, and mountainous regions. The land and sea breezes are classified into five types according to the behavior of the sea breeze at several locations in the study area. The most frequently occurring type is characterized in the following. Along the southern coast of Osaka Bay, the sea breeze from Osaka Bay changes with time into that from the Kii Channel. At the same time, along the coast of the Seto Inland Sea the sea breeze contains a predominant easterly component. For this type, several interesting features are further elucidated: (1) the simultaneous onset of the coastal sea breeze and the valley or upslope wind in the mountainous region is clearly seen, especially in the eastern Chugoku area, (2) the meeting of the southerly sea breeze from the Seto Inland Sea and the northerly breeze from the Sea of Japan occurs around the region of the mountain ridges in eastern Chugoku, (3) the alternation of converging sea breezes from surrounding seas forms a uniform southerly sea breeze from the Kii Channel at Awaji Island, (4) the southerly sea breeze continues until the late afternoon in the coastal area of the Kii Channel and Osaka Bay. Other types are discussed and compared with the above type for the mature stage of the sea breeze. The relationships between the occurrence of the land and sea breeze and general meteorological conditions are also analyzed.
