Sea surface temperature (SST) in the Indonesian Seas drives atmospheric deep convection, influencing regional and global climate. Yet, the processes controlling SST in this region remain poorly understood. Using a high‐resolution regional model that explicitly resolves internal tides, we show that tidal displacements lift cold thermocline water into the surface ocean, exposing it to vigorous surface mixing and thus enhancing the surface‐interior heat exchange. The heat exchange facilitated by tides shows strong seasonality, intensifying during monsoons in areas where the mixed layer is deep and the thermocline is shallow. This tidal exposure mechanism augments, with comparable impact, the mixing driven by internal tide breaking in the interior. However, it dominates the tidal impacts for the vertical heat exchange in the upper ocean. This novel pathway for vertical heat exchange must be represented in coarse‐resolution climate models to improve simulations of SST and air–sea interactions in the region.
A large share of energy within the global oceans lies within the mesoscale range, (100 km), where very large dynamic and thermodynamic variability has been observed. We address how the marine atmospheric boundary layer (MABL) in a trade‐wind region adapts to fast and spatially varying sea‐surface temperature (SST) st...

Marine heatwaves (MHWs) are increasing in frequency and intensity in global boundary current systems such as the Gulf Stream (GS), where ocean circulation regulates upper‐ocean heat and water‐mass properties. We examine temperature–salinity co‐evolution during MHWs in the Northwest (NW) Atlantic using satellite observa...

Marine heatwaves (MHWs) are persistent extreme warm events in the ocean that pose substantial threats to marine ecosystems, fisheries, aquaculture, and offshore energy infrastructure. In 2024, the Yellow Sea experienced the most intense MHW on record in terms of cumulative intensity, with sea surface temperature (SST)...

Many coupled climate models exhibit an Intertropical Convergence Zone (ITCZ) south of the Equator in the annual‐mean tropical Pacific that is more pronounced than observed. This bias impacts winds, wind‐driven ocean circulation, including the meridional subtropical cells, and the zonal distribution of waters supplying...

Abstract. Global shelf seas have experienced unprecedented marine heatwaves (MHWs) in recent decades. Although MHWs have been extensively studied at the global scale, their regional variability and underlying mechanisms remain poorly understood, particularly in shelf seas influenced by multiple climate modes. Here, we...
Mesoscale eddies in the Southern Ocean extend from the surface to the deep ocean and contribute to regional and global ocean heat budgets. However, sparse in situ observations have limited estimates of eddy meridional heat transport (EMHT) to the near surface, leaving deep-ocean processes poorly understood. Here we qua...
