The correlations between the tropical Pacific and Northern Hemisphere extratropical latitudes are not strong. But the correlations do suggest that variations in oceanic heat storage and transport may modulate atmospheric fluctuations on time scales that are tied to the oceanic processes.

From page 28... ...
THE CAGE PROPOSAL Ocean heat flux experiments have been proposed nationally and internationally to explore the storage, transport, and transfer of heat by the ocean. The Cage experiment was proposed by a group led by F.W.

From page 29... ...
It was thus proposed at the Tokyo Study Conference that the North Atlantic Cage experiment be redefined into a stepby-step process. This would begin with a study of the interannual variability of each of the heat budget components.

From page 30... ...
However, rather than planning for a single comprehensive experiment, opportunities for pairwise intercomparisons should be exploited in WOCE and TOGA, and possibly in special regions such as enclosed ocean basins, particularly in the North Atlantic. The comnittee urged work to improve our techniques for developing atmospheric assimilation models and for obtaining direct estimates of surface fluxes.

, will observe the Kuroshio southeast of the Ryukyu Islands, a region that may be analogous in ocean-basin heat transport to the wellstudied Florida Straits. PATHS also proposes that a transoceanic section be made to measure the heat transport analogous to the estimate of Hall and Bryden (1982)

From page 32... ...
Plans are still being developed, but the essential research elements can be summarized: ice dynamics, the role of the ocean mixed layer in the heat balance of the bottom surface of the ice, and large-scale convection and its connection to lower latitudes through deep flows into the North and South Atlantic. After 5 years of monitoring, the work could be extended from its Greenland Sea base to include the Norwegian Sea.

From page 33... ...
However, many oceanographers question our ability to design and carry out an adequate large-scale heat flux experiment in this decade. Before making a commitment to such experiments, NSF should be assured that all three methods for estimating the heat flux are technically feasible within the desired accuracy, that information on processes and not simply integral results will be obtained, and that any proposal for a nonsimultaneous Cage-type experiment will be documented with quantitative estimates of the interannual variability of the component processes.

From page 34... ...
An earth-orbiting radiation satellite is needed, here, at least, a hemispheric experiment would impose only a small additional expense. If we do carry out heat flux studies over both ocean basins, we may do so within a different context than that proposed for Cage and PATHS at the Tokyo Study Conference (Bretherton et al., 1982, Pacific Cage Study Group, 1983)

From page 35... ...
The GINS Cage experiment could be a valuable contribution to understanding the global heat balance. However, a study of the scientific feasibility is first needed, and we ought to clarify the issue of the scientific resources and manpower that could be called upon to support GINS Cage.

From page 36... ...
36 Conference recommended that a heat flux steering committee be established for "organizing and guiding the development of Cage and PATHS studies. ..." A series of precursor studies were listed, though the issue of a full commitment to the programs was sidestepped.
