Special Issue Information

Dear Colleagues,

Air–sea exchanges of momentum, heat and freshwater are known to be major contributors to ocean dynamics at a range of spatiotemporal scales. Over the last decades, major advances in ocean monitoring tools, such as the international ARGO float programme, the introduction of ocean gliders and the further expansion of coastal HF radars, as well as the further development of satellite oceanographic products and concurrent developments in ocean simulations and services like Copernicus, provide unprecedented capacity to investigate the complex interactions between the geophysical fluids that determine the planet’s climate in depth. This Special issue is an opportunity to present the current developments in the analysis and understanding of complex interactions between the atmosphere and the upper and deep ocean at a range of spatiotemporal scales, as they emerge through the exploitation of the new monitoring and modeling capabilities of the scientific community. The subjects of the presented research may include:

  • Air–sea exchanges and overturning processes;
  • Vorticity exchanges and dynamics;
  • Vertical and lateral buoyancy fluxes;
  • The role of internal waves and small-scale processes on ocean circulation and climate;
  • Interactions between the coastal and offshore ocean.

Investigating latent heat flux (LHF) variations in the western boundary current region is crucial for understanding air–sea interactions. In this study, we examine the LHF trend in the East China Sea Kuroshio Region (ECSKR) from 1959 to 2021 using atmospheric and oceanic reanalysis datasets and find that the LHF has a significant strengthening trend. This strengthening can be attributed to sea surface warming resulting from the advection of sea surface temperatures. More importantly, the LHF trend has an apparent seasonal dependence: the most substantial increasing trend in LHF is observed in spring, while the trends are weak in other seasons. Further analysis illustrates that the anomaly of air–sea humidity difference plays a pivotal role in controlling the seasonal variations in LHF trends. Specifically, as a result of the different responses of the East Asian Trough to global warming across different seasons, during spring, the East Asian Trough significantly deepens, resulting in northerly winds that facilitate the intrusion of dry and cold air into the ECSKR region. This intensifies the humidity difference between the sea and air, promoting the release of oceanic latent heat. These findings can contribute to a better understanding of the surface heat budget balance within western boundary currents. Full article

The evolution and drivers of dense water formation (DWF) in the North–Central Aegean Sea (NCAeg) during winter 2021–2022 are studied using observations from two Argo floats and the output of an operational data-assimilating model. Dense water with σθ>29.1 kgm3 was produced over most of the NCAeg, except for the northeastern part covered by Black Sea water (BSW), where the maximum surface density was <29 kgm3. The highest density waters were produced over the central and southern parts of the Lemnos Plateau and in the shallow coastal areas between Chios Island and the Edremit Gulf. Atmospherically driven transformation to the east of Lesvos Island resulted in the production of waters with anomalously high density and salinity, which flowed inside Skiros Basin, thus partly explaining its historically higher density and salinity compared to the rest of the NCAeg subbasins. The Skiros and Athos Basins were ventilated down to σθ29.35 kgm3 horizons. The 29.1 kgm3 isopycnal rose by ∼200 m, and the 29.25 kgm3 isopycnal overflowed above the ∼400 m sill depth filling the southern depressions of the NCAeg. Combining data from Argo floats, vessel casts, gliders, and a fixed-point observatory, the dense water produced in the NCAeg was observed spreading in the deep layer of the Central Cretan Sea for at least one and a half years after the formation. The cyclonic circulation of the newly formed water in the NCAeg has been observed directly for the first time using deep-drifting floats. The Eastern Mediterranean warming and salinification signal has propagated below the NCAeg sill depth. The winter average buoyancy loss was comparable to that of the peak of the Eastern Mediterranean transient (EMT) and other known years of DWF in the NCAeg; however, the high temperature of the upper layers due to long-term warming prevented the widespread formation of denser water.
