| Session Description | The Maritime Continent (MC) region is known to have substantial global climatic significance, yet models have struggled to capture the spatial distribution and variability of rainfall on diurnal to seasonal timescales. It is often argued such model deficiencies are due to the under-representation of localised mesoscale circulations associated with coastlines and topography and the misrepresentation of moist convective processes over the region. The combined effect of these shortcomings limits our ability to simulate the behaviour of important phenomena such as the passage of the Madden-Julian Oscillation (MJO) within the region, which has pervasive implications downstream on longer timescales. Despite present approaches to solve the current deadlock such as (1) increasing model resolution and (2) improving the parametrisation of moist convection, issues still remain. This session invites contributions from theoretical, observational and modelling studies that focus on convection-related processes and the interactions occurring across various spatial and temporal scales within the MC region. The goal is to assess our current state of understanding and identify the gaps so as to inform future scientific emphasis on the Maritime Continent region and help break the tropical barrier to global weather and climate prediction. |
