Oort, A. H., 1987: The search for unity in the climatic system. In summary of lecture series presented at L'institut d'astronomie et de géophysique, Georges Lemaître, Belgium: Université Catholique de Louvain. 1-28.

Abstract: Studies of the earth's climate system clearly show that the atmosphere, oceans, land surfaces, cryosphere and biosphere are intimately connected with each other. Some of the complexities of the climate system are due to the very different time scales found in the subsystems and due to the operation of a variety of interactions and feedback processes between them. The role of the oceans and atmosphere in storing heat seasonally and in transporting energy poleward to maintain the climatic balance is discussed in detail.
