Documentation reveals intraseasonal variability in West Africa's monsoon, suggesting significant modulation effects.

This work aims to document the intraseasonal variability of the West African monsoon using historical datasets.
Analysis of daily gridded datasets of rainfall and convection from 1968 to 1990.
Composite analysis based on rainfall indices during wet and dry sequences.
Monitoring atmospheric features such as the ITCZ and easterly jets.
Rainfall and convection show significant intraseasonal modulation at 10-25 and 25-60 day timescales.
Wet sequences are associated with enhanced convection and stronger monsoon flows, while dry sequences show the opposite effects.
A westward-propagating signal from eastern Africa to the western tropical Atlantic influences monsoon dynamics.

Sultan et al. (2003) studied this question.
