摘要
通过对已发表的中国东部季风区小冰期气候重建结果和全球不同气候模式的对比分析,探讨我国季风区小冰期的气候干湿响应模式.本文认为:中国季风区小冰期的干湿变化受到西伯利亚冷高压的影响,华北和东北受影响最大,而中部和南部季风区变化机制更为复杂;我国季风区的小冰期存在以秦岭淮河(约34°N)为大致分界的北部冷干和南部冷湿模式,这种模式在千年或更长的时间尺度上的存在性,需要更多高分辨率的古气候资料以及模拟数据进行探讨.
A review on previous papers focused on the palaeoclimate changes since the Little Ice Age( 1500-1900 AD,LIA),and the climate variability modes affecting moisture are compared and analyzed to demonstrate the hydroclimate pattern in Eastern China that affected by East Asian summer monsoon( EASM) since the LIA. This paper suggestes that: The Siberian High may control the hydroclimate changes in EASM during the LIA,and the north deeply,and the central-south could be more complicated. There should be a demarcation line around 34 o N with a general cole-dry and cold-wet pattern in the northern and southern,in EASM,during the LIA. However,we are not sure that millennium or longer time scales consisted this pattern,and it's essential for more palaeoclimate and simmullation work on regional and global scales.
