气候系统准平衡态的维持决定于大气-海洋的经向热量输送.由于全球海陆分布南北半球严重不对称,海洋向极热量输送关于赤道也是非对称的.然而,全球热量输送的一个最显著特征就是大气-海洋总经向热量输送关于赤道反对称.这暗示着大气经向热量输送会弥补海洋热量输送的非对称性,同时也说明大气与海洋热量输送之间存在着某种约束关系.对这一基本问题的深入研究有可能揭示一些气候系统的关键约束因素,减少复杂气候系统的自由度或不确定性,使得人们能以更简洁的方式理解气候系统及其变化.在变动气候背景下,大气-海洋经向热量输送的变化以及这二者之间可能存在的“Bjerknes补偿”关系的研究,是目前气候变化研究领域前沿课题之一.“Bjerknes补偿”所暗示的大气-海洋经向热量输送的协同变化揭示了海气系统的一个耦合方式,将极大加深人们对复杂气候系统变化的理解.
The maintenance of the quasi-equilibrium of the climate system is determined by the meridional heat transfer from the atmosphere to the ocean, and due to the severe asymmetry of the global land-sea distribution in the northern and southern hemispheres, the ocean is extremely asymmetric to the extreme heat transport over the equator.However, one of the most prominent features of global heat transport Is the atmospheric-oceanic meridional heat transport on the equatorial antisymmetry, which implies that the meridional heat transport in the atmosphere compensates for the asymmetry of ocean heat transport and also shows that there is some constraint between atmospheric and ocean heat transport. An in-depth study of this basic issue has the potential to reveal some of the key constraints of the climate system and to reduce the degree of freedom or uncertainty in the complex climate system so that people can understand the climate system and its changes in a cleaner way. , Atmospheric-oceanic meridional heat transfer and the possible “Bjerknes compensation” relationship between the two are one of the frontier topics in the field of climate change research. “Bjerknes Compensation” implies that the atmosphere - The synergistic change of oceanic meridional heat transport reveals a coupling mode of the sea-gas system that will greatly deepen the understanding of complex gas System change understanding.
