Decadal-centennial hydroclimate variability over eastern China during the last millennium: Results from the product of Paleo Hydrodynamics Data Assimilation
摘要
Abstract
Decadal-centennial hydroclimate variability over eastern China during the last millennium is investigated using the product of Paleo Hydrodynamics Data Assimilation (PHYDA).Results reveal that the PHYDA depicts a more homogeneous temporal pattern during the early part of the Little Ice Age with other reconstructions than those during the other periods,and could also identify the droughts of 1352-90 AD,1445-98 AD,1580-94 AD,and 1626-65 AD during this period.On centennial time scales,the PHYDA shows that the linkage between the Palmer drought severity index over eastern China and the Atlantic Multidecadal Oscillation (AMO) index is more marked than that with the El Ni(n)o-Southern Oscillation and the location of the intertropical convergence zone over the Asian-Australian monsoon area during the period after the 1350s.For the decadal droughts,the PHYDA suggests most of the drought events during the last millennium were linked to the El Ni(n)o-like mean states and the negative AMO states.关键词
