A DYNAMICAL MODEL FOR INVESTIGATION OF THE BIENNIAL EQUATORIAL STRATOSPHERIC OSCILLATION.

Abstract

An eight-level primitive equation model is constructed for study of the biennial oscillation. The longitudinal dependence is removed by integration around latitude circles, but the Reynolds stress terms are retained by parameterization in terms of the averaged flow. The forecast levels in the vertical are arranged so as to give the highest resolution at the highest atmospheric levels. The top layer extends from 0 to 2 mb, whereas the bottom layer extends from 500 to 1000 mb. The energy source is related to variable heating in the ozone layer by means of the normal season variations of insolation. It is assumed that the vertical distribution of heating is known. The calculations are to be carried out in 10-minute time steps, using 2 degrees of latitude grid spacing, extending from 30 degrees N to 30 degrees S latitude. The time scale is compressed so that a complete 1-year cycle in the energy source takes place in 4 months. (Author)
