【摘要】

：

过去轨道时间尺度上热带太平洋的类ENSO 气候态变化，一直是古气候学界争论的焦点。赤道西太平洋MD10-3340 站近240 千年以来的陆源沉积物组分、浮游有孔虫氧同位素和Mg/Ca 比值古温度等重建记录，反映赤道西太平洋的区域降水和温跃层海水温度主要呈现岁差周期特征，其相位滞后岁差参数约270°、与赤道9 月份辐射量变化近同步。

Optimal Precursory Disturbances for ENSO Events:Implications to Target Observation for ENSO Predicti

By superimposing initial sea temperature disturbances on normal years,we revealed the precursory disturbances that are most likely to evolve into El Ni(n)o and La Ni(n)a events within an Earth System

Ocean Heat Content(OHC)Anomaly during Different Phases of the Solar Cycle in the Tropic Pacific

Several studies have found that,the quasi-decadal(~11year)solar signal does exit in the Tropic Pacific,but not very significant,its response to the solar periodic radiation forcing is still on debate.
