In the present study, we extend the observational analysis of the AMMA dataset to the period of 6 to 31 July 2006, in order to further analyse in a more systematic way the main features of the convection observed in Sahelian Africa during the pre-onset and onset of the monsoon, and to further understand the transition from dry convection to shallow convection and from shallow to local deep convection.
A description of the data used in this study is given in section 2. The methods used to characterize the type of convection for July 2006 and the result of the classification are described in section 3. The analysis of triggering factors and processes differentiating the convection days are documented in section 4. Section 5 summarizes and concludes the study.
