A detailed assessment of each component of the heat budgets for the surface and the earth-atmosphere system in the central Arctic, for both an ice-covered and an ice-free ocean. These estimates suggest that the annual heat balance at the surface for an ice-free Arctic would be near zero rather than strongly positive as suggested by Donn and Shaw. The sources of this discrepancy are identified and discussed. The annual patterns of atmospheric cooling for both present and ice-free conditions are obtained as residuals. The relation of these patterns to general atmospheric circulation and glacier accumulation is discussed, with the conclusion that an open Arctic Ocean would be conducive to glacier accumulation in Canada and Scandinavia. 22 pp. Bibliog.
This report is part of the RAND Corporation Paper series. The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
