Abstract: The occurrence and movement of water in all its phases (liquid, vapor and solid) is intimately linked to the energy cycle of the climate system. It is also a major factor in several of the global biogeochemical cycles, including Carbon. Variability and change in any one of the cycles affects the others. The strength of the couplings determines the degree of the effects. Current Earth System models have a wide range of prescribed degree of couplings among the cycles that leads to uncertainty in the projection of climate variability and change. In this presentation new measurements from a set of Earth-orbiting satellite instruments are used to form observation-based estimates of coupling among the major global cycles. Implications for the role of the water cycle in the climate system and future regional water availability are addressed in this presentation.
