STATISTICAL-DYNAMICAL METEOROLOGICAL PREDICTIONS.
Abstract
This investigation concerns the level of energy balance in the atmosphere. Previous work has shown that, for given external influences, total dissipation of kinetic energy, together with the amplitudes of the meridional temperature field and the large-scale disturbances, in a longterm balanced state, and in a highly simplified physical model, are uniquely determined by the horizontal scale of the large-scale disturbances. It is of interest to explore whether existing differences in horizontal scales are stable enough to explain significant year-to-year variations in the long-term balance. In a wider sense, taking also other kinematical characteristics into account, this is related to the problem of whether the atmosphere for given external influences assumes a number of quasi-stationary states besides oscillating around its seasonal climatological averages. Also of interest is the degree of coupling between different relevant parameters. This will make a statistical attack on the long-range forecasting problem more promising because of increased significance in the statistical formulae and because of greater stability. (Author)
