摘要
The heat distributions in the upper layers of the ocean have been studied and some important low frequency oscillations （LFOs） are already found and quantified by using various characteristic factors. In this paper, the ‘heat center＇ of a sea area is defined with a simple method. Then the temperature data set of the upper layer of the global ocean （from surface down to 400 m, 1955-2003） is analyzed to detect the possible LFOs. Not only some zonal LFOs, which were reported early, but also some strong LFOs of the vertical and meridional heat distribution, which might imply some physical sense, are detected. It should be noted that the similar vertical oscillation pattern can be found in the Pacific Ocean, Atlantic Ocean and Indian Ocean. Results from some preliminary studies show that the vertical LFO might be caused by the solar irradiance anomalies. This study may help reveal some unknown dynamical processes in the global oceans and may also benefit other related studies.
在海洋的上面的层的热分布被使用各种各样的典型因素学习了，一些重要低频率摆动(LFO ) 已经被发现并且确定。在这篇论文，“一个海区域的热中心”与一个简单方法被定义。然后全球海洋的上面的层的温度数据集(从在 to400m 下面的表面， 1955-2003 ) 被分析检测可能的 LFO。不仅一些带的 LFO，早被报导，而且垂直、南方的热分发的一些强壮的 LFO 被检测。类似的垂直摆动模式能在太平洋，大西洋和印度洋被发现，这应该被注意。从一些初步的研究的结果证明垂直 LFO 可能被太阳的发光异例引起。这研究可以帮助在全球海洋揭示一些未知动态过程并且可以也有益于另外的相关研究。
