The sea surface temperatures set by the dynamics of the tropical oceans interact strongly with the tropical atmosphere, affecting winds and patterns of convection and precipitation, coupling back with the ocean dynamics. Atmospheric teleconnections can also affect conditions over many parts of the globe. The ocean climate indices above, indicators of tropical sea surface temperature anomalies, help capture the seasonal and interannual variability of the climate system. This quick overview above of some of last week's anomalies is extracted from the OOPC state of the ocean climate overview

Gathering the data necessary for these and other climate indices, as well as to underpin climate monitoring, forecasting, and research, is the goal of the initial ocean observing system for climate
