A 40‐ to 60‐day oscillation in the source region of the Somali Current during 1976

Abstract

Evidence is presented for a 40‐ to 60‐day oscillation in the longshore current and temperature fluctuations that were measured during 1976 in the Somali Current regime off Kenya by Düing and Schott (1978). It is suggested that this equatorial oceanic oscillation is excited by long‐period local wind fluctuations which are associated with the global tropical 40‐ to 50‐day day oscillation first detected by Madden and Julian (1971, 1972).
