简介：在全球海洋的由空至海的相互作用的七个关键区域被每月吝啬的海面的全球数据的综合分析决定温度(SST)，地面风，温度，湿度，海面可感热和潜伏的热流动。在在每个关键区域的SST和各大气的元素之间的时间落后关联焦点地被分析在不同关键区域暴露一样和由空至海的相互作用的不同特征。由空至海的热相互作用在每个区域，SST，温度和湿度是强壮的结果表演能相当被对方代替，特别地在中央东方太平洋和南方印度海洋。SST上的动态效果在不同区域是不同的，在中央西方的太平洋，如此的效果是更重要的。在可感热，潜伏的热和SST之间的关联在东方太平洋，西方的太平洋和二个主要季风区域是更重要的-西北的太平洋和南方印度海洋。由在每个关键区域分析SST和每个大气的元素的持续关联概率，我们进一步知道元素的异例，在哪个区域并且在时期很好在哪个被支撑或容易破坏了。这不仅对预言，而且到由空至海的相互作用的物理机制的讨论有益。

简介：在空气的顶的放射预算在气候研究起一个关键作用。比作宽带流动，幽灵似地解决的出去的longwave放射或流动(OLR)，与在不同乐队的富有的大气的信息，在GCM的评估有明显的优点。不同于需要辅助大小和信息的方法，这里，我们拿大气红外线更健全(表情)观察作为一个例子当模特儿由尖分布造一个前後一致的算法(ADM)，完全基于发光观察，在热带海洋上估计清楚天空的幽灵似地解决的流动。作为为如此的ADM的关键步骤，景色类型评价在选择表情隧道从发光和亮度温度被获得。然后，宽带OLR象一样合成光谱流动被导出由光谱ADM并且使用合成系列和谷神星验证(云和地球绚烂的精力系统)观察。处于大多数状况，之间的吝啬的OLR差别光谱ADM产品和CERES观察在钫?以内??醰顣鱎???????？？
