Increasing the upper ocean heat of the tropical Pacific, a key sea area in the Earth's climate system, is likely to lead to a wetter monsoon region in eastern Asia. On the 20th, the international academic journal Nature published on line the latest scientific research achievements of Professor Jian Zhimin's team from the State Key Laboratory of Marine Geology of Tongji University - the regulation of water vapor transmission between ocean and land by ocean heat content in the warm pool area. This study found that tropical ocean warming has a strengthening effect on the East Asian monsoon climate. It is the first time to explain the driving role of low latitude ocean processes in climate evolution from the perspective of energetics, which provides the latest insights into the relationship between sea land water thermal cycle. In recent years, under the background of global warming, the ocean heat continues to increase, which is considered to be closely related to the enhancement of destructive power of landfall typhoons in East Asia. However, the relationship and mechanism between ocean heat and land rainfall are still unclear. The shortage of modern instrument observation data has greatly limited the human ability to predict and prevent extreme weather/climate disasters. It is urgent to use geological records and numerical simulation and other means to study the past changes in ocean heat content and their regulatory effects on the sea land energy/water cycle. Jian Zhimin team first used the planktonic foraminiferal microfossils in 10 deep-sea sediment cores in the warm pool area to reconstruct the changes in the upper sea water (0-200m) heat content over the past 360000 years, and found that the reconstruction records of the warm pool heat content were very consistent with the shape and amplitude of the heat content curve of the transient simulation of the numerical model of the Earth's climate system. The team also reconstructed the residual oxygen isotope of surface seawater in the warm pool area. The results are consistent with the change of heat content in the warm pool. Both of them change synchronously with the oxygen isotope of atmospheric rainfall recorded by Chinese stalagmites in the precession cycle: that is, the heat content of the warm pool increases, corresponding to the heavier residual oxygen isotope of seawater and lighter oxygen isotope of stalagmites. Jian Zhimin said: "This shows that on the 10000 year scale astronomical cycle, the heat change of the warm pool can regulate the water vapor transmission between the Pacific Ocean and the Asian continent. When the heat of the warm pool increases, the tropical sea surface evaporation increases, the water vapor converges, and transmits to the adjacent land in the form of monsoon and typhoon, leading to an increase in rainfall in East Asia." This scientific discovery is also the distillation of the team's research on paleoceanography of the subsurface seawater of the Western Pacific Warm Pool over the years. This study comprehensively uses modern observations, paleoenvironmental proxy indicators, as well as transient simulation of air sea coupling model and water isotope numerical model to explore the latent heat transfer of water vapor from the perspective of upper ocean heat content (rather than surface seawater temperature) in the warm pool area, and measures the intensity of global monsoon water cycle through the gradient of water isotopes between sea and land, which not only expands the new field of energetics research on ancient oceans and climate, It can also provide a new idea of "discussing the present from the past" for modern and future climate change.
