Abstract Many human activities rely on accurate knowledge of the sea surface dynamics. This is especially true during storm events, when wave‐current interactions might represent a leading order process upper ocean. In this study, we assess and analyze impact including three wave‐dependent processes in ocean momentum equation Met Office North West European Shelf ocean‐wave forecasting system accuracy simulated circulation. The analysis conducted using currents Stokes drift data produced by...
The vertical coordinates (VC) are one of the most important set configuration options an ocean model. Optimisation is, however, a non-trivial exercise. We compare nine configurations to investigate different VC and contrast Vanishing Quasi-Sigma (VQS), partial step z-level, s-z hybrid Multi-Envelope (MEs) approaches. Using NEMO model simulations, hierarchy experiments conducted, including: unforced multi-year climatological simulations with comparisons against tracer profile observations,...
We present a numerical platform named Structured and Unstructured grid Relocatable ocean for Forecasting (SURF). The is developed short-time forecasts designed to be embedded in any region of the large-scale Mediterranean System (MFS) via downscaling. employ CTD data collected during campaign around Elba island calibrate validate SURF. model requires an initial spin up period few days order adapt interpolated fields subsequent solutions higher-resolution nested grids adopted by Through...
Prediction of severe natural hazards requires accurate forecasting systems. Recently, there has been a tendency towards more integrated solutions, where different components the Earth system are coupled to explicitly represent physical feedbacks between them. This study focuses on rapidly developing waves under extratropical storms understand impact wave source term parameterisations in WAVEWATCH III (WWIII) model (ST4 and ST6) coupling strategies (surface roughness closure versus surface...
Abstract A generalized methodology to deploy different types of vertical coordinate system in arbitrarily defined time‐invariant local areas quasi‐Eulerian numerical ocean models is presented.

Abstract. In response to an increasing demand for bespoke or tailored regional ocean modelling configurations, we outline fundamental principles and practices that can expedite the process generate new configurations. The paper develops principle of reproducibility advocates adherence by presenting benefits community user. elements this are reproducible workflows standardised assessment, with additional effort over existing working being balanced against added value generated. then...
Abstract. The sensitivity of a shelf sea model the Gulf area to changes in bathymetry, lateral and vertical resolution, coordinates river atmospheric forcing is explored. Two new models with resolution 1.8 km, named GULF18-3.6 GULF18-4.0, differing only coordinate system NEMO code base employed (NEMO-3.6 NEMO-4.0.4, respectively) are introduced. We compare them against existing 4 km PGM4 model, which based on NEMO-3.4 developed used by Met Office. use similar types quasi-terrain-following...
The Baltic Sea is a semi-enclosed brackish marginal sea in Northern Europe. It sensitive system where increased anthropogenic pressure has led to poor ecological status, with resulting hypoxia and algal blooms. circulation, hydrography stratification are strongly constrained by the bathymetric features of region net freshwater input. shallow entrance limits inflow oceanic water from North Sea, while input drives an estuarine-like circulation that leads outflow-dominated exchange....
