The purpose of this reseach is to reconstruct the wet/dry patterns in East Asia, 1771-1800, and to make some synoptic climatological discussions. The procedures and results of this research are summarized as follows: Firstly, we have collected 20 weather records, most of which are described in the old diaries. The weather records for Seoul were also obtained. Secondly, we have reconstructed the daily weather maps of Japan for 30 years (1771-1800) using the weather records mentioned above. Then we classified those weather maps into 32(=2^5) types objectively by considering the rainfall area. thus we completed the daily weather pattern calendar for 30 years(1771-1800) from June to September. Thirdly, we calculated the precipitation frequency in each year on the basis of the weather pattern calendar, and categorized the precipitation in each year into five grades( 1-5 ). In China, the wet/dry pattern charts for 500 years have already been reconstructed. Therefore, we could reconstruct the wet/dry pattern maps in East Asia by overlapping these two charts. Finally, we made some synoptic climatological discussions on the reconstructed wet/dry pattern maps, especially for the 1780's.

本研究的目的是重建1771—1800年东亚地区的干湿格局，并进行一些天气气候学上的讨论。本文的研究过程和结果总结如下：首先，我们收集了20份天气记录，其中大部分是在旧日记中描述的。首尔的天气记录也得到了。其次，我们利用上述天气记录重建了日本30年（1771-1800）的每日天气图。然后根据降雨面积客观地将这些天气图划分为32（=2^5）类。这样我们就完成了30年（1771-1800）从6月到9月的每日天气模式日历。第三，基于气候模式历计算各年降水频率，并将各年降水划分为5个等级（1 ~ 5）。中国已经重建了500年的干湿格局图。因此，我们可以通过重叠这两个图来重建东亚干湿格局图。最后，对重建的干湿型图，特别是18世纪80年代的干湿型图进行了天气气候学上的讨论。
