Description We examine the organization and temporal evolution of deep convection in relation to the low level flow over the Indian Ocean by a synergistic analysis of several satellite datasets for wind, rainfall, Outgoing Longwave Radiation (OLR) and cloud liquid water. We show that during the active Indian monsoon season, symmetric instability is present and is directly linked to organized convection and the off-equatorial location of the InterTropical Convergence Zone (ITCZ). The inertial regime interacts with and is controlled by monsoon and cross-equatorial flow. We characterize the dominant regimes of deep convective organization and the possible ocean–atmosphere mechanisms that control them at different phases of the Indian Monsoon. Ongoing work on development of algorithms for automated identification of convective regimes in climate data and their application and testing on 30 years of OLR data are discussed, and preliminary results of the double ITCZ organization in climate data are presented.
