作为联系大气和海洋的纽带,海表混合层对地球气候系统及其变化起着重要的作用,而垂直混合的日变化是混合层动量和热量平衡中的关键过程。由于混合过程的非线性和不可逆,海表混合层的日变化必然对海洋与气候系统的平衡态和长期变化有不可忽略的影响。研究表明,10W/m~2的热通量误差可以造成模拟结果很大的不同,然而,目前各种热通量产品之间的差异达到40w/m~2,这给海洋和气候模式的结果带来相当大的不确定性。海表通量的
As a link between the atmosphere and the ocean, the sea surface mixing layer plays an important role in the Earth’s climate system and its changes. The diurnal variation of vertical mixing is a key process in the mixing layer momentum and heat balance. Due to the non-linear and irreversible mixing process, the diurnal variation of the mixed layer in the sea surface will inevitably have an insignificant effect on the equilibrium and long-term changes of the ocean and climate systems. The results show that the heat flux error of 10W / m ~ 2 can cause great difference in simulation results. However, the difference between the current heat flux products reaches 40w / m ~ 2, which gives the results of ocean and climate models Bring about considerable uncertainty. Sea surface flux
