We develop a linear theory for the effects of partial boundaries on low frequency waves of the kind thought to be important in the seasonal and interannual variations of the equatorial circulation. The Western partial boundary case (e.g. Brazil) differs from the Eastern one (e.g. the Gulf of Guinea) by the presence of short Rossby waves trapped along the North-South part of the boundary which form a boundary current accomplishing the required meridional redistribution of the zonal mass flux. There is a discontinuity in the dynamic topography at the corner of the East-West current at this point. Calculations for the world's equatorial ocean basin shapes are discussed. Calculations carried out for equatorial islands show that propagation of such low frequency waves will not be affected significantly by any island of the real equatorial ocean. (Résumé d'auteur)
