Short summary

We characterize the signature of an intense storm-induced coastal upwelling along the north-western coast of the Balearic Islands in 2021 using a high-resolution operational prediction model. The upwelling, with a duration of 3 d and a spatial offshore extension of 20 km, led to cross-shore surface temperature differences of up to 6 °C. It was the most intense event of the past 9 years in terms of the impact on temperature and the second-most intense event in terms of cross-shore transports.
