AB Large‐amplitude internal solitary waves (ISWs) propagating eastward toward the Alboran Seahave long been known in the Strait of Gibraltar. New in‐situ data and satellite images evidence northwestwardpropagating ISWs. These waves are probably the reflection of the well‐known eastward propagating wave alongthe Moroccan shelf. A simple 2D‐vertical section, run with the compressible non‐hydrostatic Coastal andRegional Ocean COmmunity model, illustrates that the Moroccan slope is conducive to reflection of incidentsolitary waves of amplitude observed in the Strait of Gibraltar. A clear signature of these waves in the Tarifahigh‐frequency sea level oscillations is depicted that paves the way to studies of the seasonality of ISWs in theStrait of Gibraltar with the long‐time series of sea level at Tarifa. The polarity of the reflected waves, observedwith Acoustic Doppler Current Profilers/Conductivity‐Temperature‐Depth array moorings, presents a slightvariability possibly due to the internal tide oscillations. The reflected ISWs arrives at the mooring location inphase with the peak of the internal tide. For the strongest tide, the pynocline approaches a critical point where thepolarity of the ISWs might reverse.
