Dakar 2005: Conference Themes
West African Monsoon and Global Climate
The 2-way in-teractions between the West African Monsoon (WAM) and the rest of the globe are important for determining the variability of the WAM and its global impacts on intraseasonal-to-decadal time-scales. Research areas under this theme include
- Variability and predictability of the WAM (nature and role of teleconnections, intraseasonal variability including easterly waves, predictability issues and the role of the ocean, detection of the global change),
- Monsoon processes (scale interac-tions, the seasonal cycle and the monsoon onset), and
- Global impacts of the
WAM (e.g. on tropical cyclones, aerosol variability, atmospheric chemistry).
