Abstract

In this study, I have created a climate disaster database using climate disaster records of Japan and China, and the climate variation of East Asia in the early Little Ice Age has been reconstructed. The main results are as follows: The number of disaster data has increased slowly in later times. There are more Kinki district, along the Yellow River and along the Yangtze River, and their contents often relate to the moisture state. Climate disaster records are classified into i) index of climate variation, ii) abnormal circulation and disaster, iii) remarkable turbulence and disaster, and iv) complex disaster. The Japanese Records have many disasters including strange phenomena, but the Chinese Records have many disasters including heavy damage. Complex disaster increased from the 15th century. There were more droughts in the inland, and more floods in the seashore. The disaster distribution map of each year is classified as one of the 4 types: dryness (D), moistness (W), north-moist and south-dry (WD), and north-dry and south-moist (DW). There may be multi-decadal oscillation in the appearance of the types, and the end of 14th century and the middle of 15th century had the dryness tendency, but the beginning and the end of 15th century had the moistness tendency. On the East Asia, climate variations are similar, but are affected by social elements, such as city development. The external forces of volcanic activity and solar activity have influence, and are related to the multi-decadal oscillation in the ocean / air. The praying ceremony for rain restored from the middle Ming dynasty and there might have been a cultural background. In the same age, famine and cannibalism had the maximum occurrence, but there was not any cultural background.
