Short summary
We present a high-resolution modelling effort to investigate the possible end-of-century evolution of the main physical processes in the Adriatic Sea in a severe climate change scenario, with an ensemble approach (i.e. use of multiple simulations) allowing us to control the uncertainty of the predictions. Our model exhibits a satisfactory capability to reproduce the recent past and provides a basis for a set of multidisciplinary studies in this area over a multi-decadal horizon.

We propose a new point-prediction model, the DEep Learning WAVe Emulating model (DELWAVE), which successfully emulates the Simulating WAves Nearshore model (SWAN) over synoptic to climate timescales. Compared to control climatology over all wind directions, the mismatch between DELWAVE and SWAN is generally small compared to the difference between scenario and control conditions, suggesting that the noise introduced by surrogate modelling is substantially weaker than the climate change signal.

Short summary
In this work, we study a Mediterranean cyclone that occurred in February 2023 and its relationship with a particular seismic signal called microseism. By integrating the data recorded by seismic stations, satellites, HF radar and wavemeter buoy we are able to obtain information about this event. We show how an innovative monitoring system of the Mediterranean cyclones can be designed by integrating microseism information with other techniques routinely used to study meteorological phenomena.

Short summary
This study investigated how Mediterranean cyclones impact chlorophyll-a dynamics. Using reanalysis data, ARGO floats, and satellite imagery, we found that slow-moving cyclones significantly uplift the deep chlorophyll maximum. Upwelling and air-sea heat exchange were key mechanisms driving this uplift, enhancing nutrient availability and primary productivity. These findings highlight the strong influence of cyclone intensity and movement on biogeochemical processes in the Mediterranean Sea.
This study investigated how Mediterranean cyclones impact chlorophyll-a dynamics. Using...
