Summary

Previous analyses of Arctic temperature trends have been restricted to land-based measurements on the periphery of the Arctic Ocean. The paper shows the results of an analysis of readings on and over the Arctic Ocean itself. These measurements have been produced by Russian ice-stations which drift over the ocean areas, together with observations by instruments parachuted from high-flying US "Ptarmigan" weather reconnaissance aircraft. The readings were taken over twenty to thirty-eight years between 1950 and 1990. The results show trends of cooling at the surface and warming at levels in the troposphere. It is suggested that current prediction models lack an accurate treatment of thermodynamic exchanges at the ocean surface. D.W.H.
