Numerical study of Balearic meteotsunami generation and propagation under synthetic gravity wave forcing

•Meteotsunami generation, amplification and propagation is investigated using synthetic forcing.•Contributions of Mallorca shelves and Menorca Channel are quantified for different gravity wave forcing angles and speeds.•The Channel is the key build-up region. Shelves do not significantly contribute to substantial oscillations in Ciutadella.•Channel bathymetry serves as a focusing lens for meteotsunami waves.•Meteotsunami speed under sub- and supercritical forcing is estimated. First order estimate of its magnitude is derived.
