but from September to June atmospheric cold fronts coming from continental North America motivate wind burst episodes affecting the wind direction towards the southeast in all the GoM (events locally known as "Nortes")\citep{g2020}. Wind stress forcing and bottom friction are the main drivers of the ocean currents over the shelf, but also the water column stratification has been found to be an important factor (\citealp{r2016}, \citealp{jl2016}, \citealt{Jouanno_2018}).
