Several Problems on Oceanography Linked with Climatic Variability

Recent diagnostic studies associated with the world ocean circulation and its link to climatic variability are reviewed. The following problems are discussed: the great world ocean conveyor, the role of the word ocean circulation in the heat balance of the planetary climate, the role of the world ocean conveyor in the global water cycle, and the impact of stability and variability of the thermohaline circulation on climatic variability.
