  abstract = {{T}he objective of this study is to document the circulation in the vicinity of {L}a {R}eunion and {M}auritius islands, i.e., within 500 km offshore, on the intraseasonal time scale, using a high-resolution realistic modeling strategy. {T}he simulated sea level anomalies, water mass properties, and large-scale circulation compare favorably with satellite and in situ observations. {O}ur high-resolution simulation suggests that the currents around the islands are maximal locally, oriented southwestward, to the southeast of both islands which is not visible in low-resolution satellite observations. {I}t also highlights the high degree of variability of the circulation, which is dominated by westward propagating features. {T}he predominant time scale of variability is 60 days. {T}his coincides with the period of a barotropic mode of variability confined to the {M}ascarene {B}asin. {T}he characteristics of the westward propagating anomalies are related to baroclinic {R}ossby waves crossing the {I}ndian {O}cean but only in the long-wave resting ocean limit. {T}racking those anomalies as eddies shows that they also have a meridional tendency in their trajectory, northward for cyclones and southward for anticyclones, which is consistent with previous studies. {S}ensitivity experiments suggest that they are predominantly advected from the east, but there is also local generation in the lee of the islands, due to interaction between the circulation and topography.},
