The Maritime Continent (MC) and Indo-Pacific region, bounded by Eurasia and two large oceans, play a pivotal role in shaping the global climate. Intense convective activities and systems are generated and maintained on multiple spatial and temporal scales, exerting far-reaching influences by modulation of monsoons, Walker/Hadley circulations, and wave-induced teleconnections. In the meantime, ocean processes in this region, such as the Indonesian throughflow, also play an essential role in inter-ocean heat/salt exchange associated with the global conveyor belt and hence the global climate. However, given that it acts as an important source and the bridge in the regional/global climate, our understanding of this region remains shallow due to its complex nature formed by the intricate land-sea distributions and highly coupled land-ocean-atmosphere processes, such as cloud-aerosol and cloud-radiative interactions, land-sea breezes, coupled boundary layer evolution, air-sea fluxes, and atmospheric/oceanic Kelvin and Rossby waves.
This collection aims to improve our understanding of the complex land-ocean-atmosphere coupling processes within the MC and Indo-Pacific region and their regional/global climate impacts, which is also expected to enhance the performance of current regional and global models that are suffering from persistent, systematic errors and limited simulation and prediction skills. This collection solicits contributions on physical processes related to convection, air-sea interaction, atmospheric composition, radiation, and ocean processes over the MC and Indo-Pacific region, and contributions could include observations, numerical modeling, data assimilation, reanalysis products, predictability, and theory.
