Session ID#: 11510
Session Description:
Through its enormous heat capacity, the ocean plays a leading role in storing transient energy imbalances in the climate system – both forced and as a result of natural variability.. The recent debate on the so-called global warming 'hiatus' highlights the need for improving our understanding of mechanisms that control radiative imbalances at the top of atmosphere and in the magnitude (and uncertainty) of implied oceanic heat uptake, together with its spatio-temporal distribution, on interannual to decadal time scales. Such understanding is also a prerequisite for developing skillful decadal prediction. This session solicits contributions dealing with critical assessment of the uncertainties in Earth radiative imbalance estimates; estimates of ocean atmosphere heat exchange; mechanisms of ocean heat content (OHC) variability inferred from observations and/or models; context of the recent 'hiatus' period within climate variability over the last century; gaps in the current global ocean observing systems and implied uncertainties in recent OHC change estimates; estimates of radiative forcing variability over the last decades; and observational and data assimilation requirements for improving OHC estimates.
