Abstract : The characteristic features of the sky cover in the northern hemisphere and their relationship to large-scale vertical motion are discussed. Evidence is presented in support of the hypothesis that the principal characteristics of the sky cover--amount and average height of cloud tops--are primarily determined by the largescale vertical motion, with convection playing a secondary role. Some implications of this hypothesis for analysis and forecasting of cloudiness and for the use of satellite observations of clouds and radiation in studies of atmospheric dynamics are mentioned.
