A proposed Soviet research program to improve long-range weather forecasting by taking into account the influence of oceans on the development of atmospheric macroprocesses. The first state must consist of the development of physical concepts about the nature of the processes of interaction between the atmosphere and the hydrosphere. The second stage must involve the study of the interconnections in the "ocean/boundary layer of the atmosphere/free atmosphere" system by numerical methods and the development of interaction models by hydrodynamic and physico-statistical methods. The eventual goal is the practical application of the results of these investigations by developing both existing and new methods of long-range forecasting. Detailed monitoring of heat budget and thermal forcing could easily be extended down to 50 deg. The periods of variation in the hydrometeorological elements indicate that observations for no less than seven years must be recorded.
