Short summary

The impact of boreal spring intraseasonal wind bursts on sea surface temperature variability in the eastern tropical Atlantic in 2005 and 2006 is investigated. The cooling events induced by southerly wind bursts are modulated by local and remote forcing. A particularly strong wind event and a strong cooling occurred in mid-May 2005. It appears as a decisive event in the West African monsoon onset. This study emphasizes the need to further document and monitor the South Atlantic region.
