Abstract

Surface and 500-mb pressure series based on 12- and 24-hourly observations for 1958, 1966, 1965–66, and 1965–69 are analyzed for several South African stations. Preferential pressure fluctuations with periods of about 6 days are best-developed over southern and eastern coastal regions and are shown to advance from Cape Town to areas northwest of Durban at rates in good agreement with synoptic experience.
