Synoptic waves in the Tropical Atlantic atmosphere and their relationship with the dynamics of the intra-tropical convergence zone

Intra-annual variability of the wave activity in the eastern Tropical Atlantic atmosphere is studied through the use of multidimensional spectrum estimation involving the method of maximum entropy. Investigation of the composition of the wave field spectrum relies on the pressure data recorded by four weather stations located on the West African coast. It has been found that in the region under study meridionally-orientated waves occur whose dynamics are largely determined by meridional displacements of the intra-tropical convergence zone in the annual cycle.UDK 551.460:629.78.Translated by Vladimir A.
