AB:
The temperature and pressure differences between Tokyo and Nagasaki were applied for reconstruction of the
past climate conditions. January and July in each year since the 1820fs were divided into several types
characterized by sea level pressure patterns. The findings indicated that the warming after 1900 (after the decline
of the so-called Little Ice Age) and again after 1960 can at least partly be attributed to a increase in frequency of
warm circulation types at the cost of cold types. The different nature of the shift in circulation types around 1900
and 1960 suggest that the mechanisms behind these warmings are of a different nature.
