Climate Change during historical times in Monsoon Asia and around North Atlantic Ocean is treated in this study. "Historical Climate Data Base" is continued to create and climate data are used from other past climate data base. Using them, climatic difference between "Medieval Warm Period" and "Little Ice Age" are compared. Some remarks of this study are as follows.1. "Historical Climate Data Base"Records of daily weather and climatic hazard are chosen from old diaries in the National Diet Library and many prefectural libraries. Those data are collected into this data base and weather data are incr eased not only in the recent age but also in middle age and old age.2. Data exchange between other past climate data base in Japan and foreign countriesThis Historical Climate Data Base can be used on internet. Their address (URL) is as follow : http : //edcgeo, edu.toyama-u.ac.jp.3. Recent results on the climate change during historical timesThose are clarified on the climate change during historical times through this study.1) It was warm in the "Medieval Warm Period" around Atlantic Ocean but it was not so clear in Japan.2) Climate change in "Little Ice Age" of Japan correlates to the change of El Nino, but the relationship between climate and El Nino is not clear around Atlantic Ocean.

本研究讨论了亚洲季风期和北大西洋周围历史时期的气候变化。继续创建“历史气候数据库”，并使用其他过去气候数据库的气候数据。利用它们，比较了“中世纪温暖期”和“小冰期”之间的气候差异。本研究的几点说明如下： 1． “历史气候数据库”每天的天气和气候灾害的记录选自国立国会图书馆和许多县立图书馆的旧日记。这些数据被收集到这个数据库中，气象数据不仅在近代有所增加，而且在中老年也有所增加。 2．日本和国外其他过去的气候数据库之间的数据交换这个历史气候数据库可以在互联网上使用。他们的地址 (URL) 如下：http://edcgeo, edu.toyama-u.ac.jp.3。关于历史时期气候变化的最新成果通过这项研究，澄清了历史时期的气候变化。1）大西洋周围的“中世纪温暖时期”气候温暖，但日本不太明显。2）气候变化日本“小冰期”的发生与厄尔尼诺现象的变化有关，但大西洋沿岸气候与厄尔尼诺现象的关系尚不明确。
