Short summary
Understanding how the ocean moves heat, nutrients, and pollution is vital for climate studies and ecosystem health. We examined eddies in the western Mediterranean Sea using innovative satellite observations from the Surface Water and Ocean Topography mission. Compared to existing data, we detected major differences in eddy patterns. These advances improve our ability to monitor the ocean, manage marine pollution, and support sustainable maritime activities.

Short summary
Marine heatwaves (1982–2024) in the senegalo-mauritanian upwelling show strong spatial heterogeneity. Shallow zones face up to 50 heat days/year, while persistent upwelling areas like Cap Blanc act as refuges. Wind relaxation drives events by weakening upwelling. The Grande Coast shows increasing vulnerability. Biologically, heatwaves reduce chlorophyll in the south, whereas Cap Blanc shows seasonal biomass increases during cold periods due to residual nutrients.

This study presents a plan for climate model experiments to better understand how changes in freshwater in the North Atlantic affect major ocean currents. We designed coordinated simulations to test their response to warming, added freshwater, and possible recovery after weakening. Comparing results across models and past climate evidence helps improve confidence in projections and assess risks of large ocean circulation changes.

Short summary
In this study, we show that the positive phase of the Atlantic Multidecadal Variability, with warmer North Atlantic surface temperatures, enhances local latent heat release and net energy input into the atmosphere. The excess energy is exported through a northward shift of the tropical rain belt, leading to increased rainfall over the Sahel. Deep convection is also enhanced while mid-level dry-air intrusion is reduced due to a weakening of the shallow meridional circulation over the Sahara.

We focus on understanding the impact of river runoff and precipitation on sea surface salinity (SSS) in the eastern North Tropical Atlantic (e-NTA) region off northwestern Africa. By analyzing regional simulations and observational data, we find that river flows significantly influence SSS variability, particularly after the rainy season. Our findings underscore that a main source of uncertainty representing SSS variability in this region is from river runoff estimates.

In recent decades three major volcanic eruptions have occurred: Mount Agung in 1963, El Chichón in 1982 and Mount Pinatubo in 1991. In this article we explore the climatic impacts of these volcanic eruptions with a purposefully designed set of simulations from six CMIP6 decadal prediction systems. We analyse the radiative and dynamical responses and show that including the volcanic forcing in these predictions is important to reproduce the observed surface temperature variations.

The impact of the Atlantic multidecadal variability (AMV) on the rainfall distribution and timing of the West African monsoon is not well known. Analysing model output, we find that a positive AMV enhances the number of wet days, daily rainfall intensity, and extremes over the Sahel and tends to prolong the monsoon length through later demise. Heavy rainfall events increase all over the Sahel, while moderate ones only occur in the north. Model biases affect the skill in simulating AMV impact.

Increasing model resolution depends on the subdomain of the Canary upwelling considered. In the Iberian Peninsula, the high-resolution (HR) models do not seem to better simulate the upwelling indices, while in Morocco to the Senegalese coast, the HR models show a clear improvement. Thus increasing the resolution of a global climate model does not necessarily have to be the only way to better represent the climate system. There is still much work to be done in terms of physical parameterizations.

Short summary
A modeling framework is introduced to understand and decompose the mechanisms causing the ocean temperature, salinity and circulation to change since the pre-industrial period and into 21st century scenarios of global warming. This framework aims to look at the response to changes in the winds and in heat and freshwater exchanges at the ocean interface in global climate models, throughout the 1850–2100 period, to unravel their individual effects on the changing physical structure of the ocean.

Short summary
OLIV3 (Observation-based LInear Vorticity Vertical Velocities) is a new global dataset of large-scale oceanic vertical velocities. It is derived from the geostrophic linear vorticity balance, combining in situ and satellite, meridional velocities and wind stress. Comparisons with reanalysis and observation-based products show that OLIV3 captures the large-scale vertical flow, its climatology, and temporal variability, providing a better description of the ocean interior than Ekman pumping.
