宝鸡黄土中０．１５Ｍａ以来植物硅酸体研究表明，年均温度、１月份和年均降水量的变化与深海氧同位素变化有很好的一致性，而７月份降水量的变化与印度洋反映季风强弱的粒度变化相类似。南海陆架孢粉研究发现，１４７００—１３９００ａＢ．Ｐ．和２２９００一２０６００ａＢ．Ｐ．气候变冷期与北大西洋沉积物中Ｈ１、Ｈ２变冷事件存在成因上的联系。全球冰量通过冬季风等因素在“轨道尺度”上可能影响了夏季风对特定地区的控制时间，从而控制了黄土区气候的年均状况，但没有影响夏季风固有的变化周期和振幅。由低纬夏季太阳辐射控制的夏季风以其准２００００ａ周期叠加在冬季风所具有的准０．１Ｍａ周期上。冬、夏季风的演化行为具有较强的相对独立性，冬、夏季风同时减弱或增强的情况是存在的。Ｈｅｉｎｒｉｃｈ事件在东亚地区不仅影响了冬季风而且影响了夏季风。
The study on phytoliths in Baoji loess since 0.15 Ma shows that the variation of annual average temperature, January and annual precipitation are in good agreement with changes of deep-sea oxygen isotopes. However, the variation of precipitation in July and the Indian Ocean reflect monsoon Strength and weakness of the similar changes in the size. South China Sea shelf sporopollen research found that 14700-13900aB. P. And 22900-20600aB. P. Climatic cooling period and the North Atlantic sediments in H1, H2 cooling events exist causal linkages. Global ice volume may affect the control of the summer monsoon over a certain area on the “orbital scale” by means of factors such as the winter monsoon, so as to control the average annual climate of the loess area, but not affect the period and amplitude inherent in the summer monsoon. The summer monsoon, controlled by low latitude summer solar radiation, is superimposed by its quasi 20000a cycle on the quasi-0.1Ma cycle of the winter monsoon. The evolution of winter and summer monsoons is relatively independent, and the weakening or strengthening of both winter and summer monsoon exist. The Heinrich incident affected not only the winter monsoon but also the summer monsoon in East Asia.
