Role of Interannual Kelvin wave propagations in the equatorial Atlantic on the Angola-Benguela current system.

2 types of Kelvin waves exist: Downwelling Kelvin waves Upwelling Kelvin waves (Lübbecke, 2013) Aim of the study Investigate the link between the linear equatorial Atlantic dynamics and the coastal variability in the region of Angola and Namibia during the 1998 – 2012 period. [...] Research Questions - How the Equatorial dynamics and Angola Benguela system variability are linked? - Is there any possibility of Prediction of extreme warm and cold events in the Benguela upwelling system (BUS) using an index estimated based on the linear equatorial dynamics (IEKW)? 1) Source of Data - Monthly Dynamic Height (Dyn ht) and 5 day mean D20°C from Prediction and Research Moored Array. [...] Results / Wind stress forcing and Kelvin wave contributions to SSHA Most of equatorial positive and negative SSHA propagations match with anomalies of wind Stress. [...] - Some positive and negative propagations of SSHA are not seen in the Angola Benguela current system due to the effect of the local wind or stratification.
