中国小冰期气候研究综述

Regional climate characteristics in China during the Little Ice Age

通过对小冰期研究文献进行综述,并对已发表的小冰期温度和降水数据进行综合对比分析,探讨小冰期时期中国气候特征的区域性.结果表明,小冰期在中国地区不同区域代用指标记录中均存在,但是小冰期的起讫及持续时间具有区域差异性,温湿配置也不尽相同.小冰期的起始时间主要呈现出由西向东推移的趋势,即青藏高原最早,华北地区次之而东部地区最晚.温湿配置的差异主要体现在东部季风区小冰期时期总体上是冷干的气候环境,而西部地区气候变化则呈现冷湿的气候特征.

A review on the previous literature of Little Ice Age is made, and the temperature and precipitation data from National Oceanic and Atmospheric Administration are compared and analyzed to discuss the regional climate characteristics in China during the Little Ice Age. Results show that Little Ice Age were found in all parts of China in the proxy record, with regional difference in start/end time, duration period, and temperature/humidity condition. The Little Ice Age in China is characterized by a moving trend from west to east in start time, or alternatively, from Qinghai-Xizang plateau to North China and then to east China. As for the climatic condition, the eastern monsoon re- gion is generally cold and dry, while the western monsoon region is cold and humid during the Little Ice Age.
