1. Discussion groups Goal: Understand interaction between the ITCZ and upwelling zones (Benguela, Guinea, eastern cold tongue) and the implications for predictability Objectives: To develop a modelling strategy Design process experiments and sustained observing systems Synthesis

2. Model strategy To improve SST forecasts (seasonal to interannual) How will tropical Atlantic region respond to global warming? What are the relevant processes? What are the key parameters/parameterizations? What observations are needed (process/sustained)?

3. Observing systems Determine mixed layer heat budget and subsurface heat content Determine surface and subsurface current structure and their role in modulating the heat budget and thermocline properties Determine the role of ocean vertical mixing on mixed layer heat budget (process oriented) Determine shallow and deep circulation in the marine ITCZ complex Refine/review proposed process and sustained observing system for the eastern Tropical Atlantic for the next 5 years (what, where)

4. Time line 9:15-10:30: existing plans coffee 11:00 –12:00: discussion Observing system group (Bill): Buys Ballotzaal Model strategy (Wilco): B4.13 Lunch 13:00 – … Present plans and discussion
