摘　　要：通过太平洋、大西洋深海温度场谱分析发现 ,地球海洋温度变化广泛盛行着 2 2年尺度的年代际周期性变化 ,这种 2 2年变化周期在深层海洋中更为清楚。分析认为 ,这是地球海洋温度场对太阳磁场周期性变化的响应。世界海洋不同海域深海温度对于太阳磁场磁性 2 2年周期响应的相位存在显著不同 ,南北大西洋海温变化相位相差 115度 ,即变化趋势接近相反 ;南北太平洋海温变化相位相差 19度 ,南太平洋变化超前。另外 ,太阳活动所激发的海温变化的振荡幅度在不同海域也有显著差异 ,北大西洋海温 2 2年周期振幅为 0 .0 7℃ ,而南大西洋则高达0 18℃ ,是北大西洋的 2 .5倍之多 !在太平洋中 ,北太平洋深海温度 2 2年周期振幅最大 ,南太平洋次之 。Based on the spectrum analysis of temperature field of the deep water of the Pacific and the Atlantic Oceans, it is revealed that variation with a period of 22 years prevails in the global marine temperature changes. Such kind cycle of changes is much clearer in deep oceans. It is believed that this is the response of the globe marine temperature field to the periodic changes of the solar magnetic field. There are obvious phase differences between the water temperatures of deep sea at different oceans. There is a phase difference of 115 degree between the temperature changes of the southern and northern Atlantic Ocean. Namely, the trends of their changes are almost contrary. The difference is 19 degree between those of the southern and northern Pacific Ocean. The change of the southern Pacific Ocean goes ahead. In addition, the oscillation amplitude of the marine temperature change stimulated by the solar activities varies greatly in different waters. The amplitude of temperature change with a period of 22 years is 0.07℃ in the northern Atlantic Ocean. While it is up to 0.18℃ at the southern Atlantic Ocean, 2.5 times of that of the northern Atlantic Ocean. In the Pacific Ocean, the amplitude of temperature change with a period of 22 year is largest in the northern Pacific Ocean, it is smaller in the southern Pacific Ocean and is smallest in the middle Pacific Ocean near the equator. \;
