21世纪海洋附应对气候强迫的变化

21st century change in ocean response to climate forcing

Stjepan Marčelja

摘要:

从陆地地面温度数据、海表温度(SST)和经验确定的SST变化与热量进入上层海洋的湍流扩散之间的关系中模拟全球平均气候强迫信息,表明了一致的联系。尽管年代际太平洋涛动(IPO)的不同阶段或陆地和海洋表面变暖之间的强烈分歧,该模型在整个20世纪都是准确的。只有在过去15年中,当SST下降到远低于趋势时,它才失败。这一发现强化了这样一种观点,即过去15年全球变暖的减缓不是由IPO的负阶段或上层海洋(顶部700米)变暖的变化引起的,而是由于海洋行为的变化导致向更深海洋的热量传送增加。

英文摘要:

Modeling globally averaged information on climate forcing from the land surface temperature data, the sea surface temperatures (SST) and the empirically determined relationship between the changes in SST and the turbulent diffusion of heat into the upper ocean demonstrates a consistent link. The modeling is accurate throughout the 20th century despite the different phases of the Interdecadal Pacific Oscillation (IPO) or the strong divergence between land and ocean surface warming. It only fails during the last 15 years when SST drops well below the trend. The finding reinforces the view that slower global warming over the previous 15 years is not a caused by a negative phase of the IPO or by the variations in the upper ocean (top 700 m) warming but results from a change in the ocean behavior leading to increased heat transfer into the deeper ocean.
