In this project, the PI's will use the global XBT data set over the 10-year period, 1979-1988 to map the thermal structure over the globe and study seasonal and interannual variability. Of particular interest are the sea surface temperature and vertically averaged temperature over the upper 400 meters, the latter addressing variability of heat content and steric sea level. An expected result is the identification of global teleconnections in the interannual variability of both sea surface temperature and vertically averaged temperature associated with El Nino and Southern Oscillation. Cross correlation with seasonal atmospheric pressure fields will allow the study of coupled modes of global variability.

在该项目中，PI将在1979 - 1988年的10年内使用全球XBT数据集来绘制全球的热结构并研究季节性和年际可变性。 特别令人感兴趣的是海面温度和垂直平均温度在400米上方，后者解决了热含量和空间海平面的可变性。 一个预期的结果是，在海面温度和与El Nino和Southern振荡相关的海面温度和垂直平均温度的年际变化中鉴定了全球远程连接。 与季节性大气压力场的跨相关性将允许研究全球变异性的耦合模式。
