  abstract = {{T}he northwestern {I}ndian {O}cean exhibits a relatively highly energetic eddy field during the southwest monsoon season between {J}une and {S}eptember. {T}his study analyzes the seasonal and interannual variability of the eddy characteristics and their trajectories in the northwestern {I}ndian {O}cean using altimetric sea surface height observations from 1993 to 2014. {A}lthough the highest number of eddies is found in the {A}rabian {P}eninsula coastal region, the strongest eddies, characterized by large radii, amplitudes, and eddy kinetic energies are found along the {S}omali {C}urrent. {T}rajectories of anticyclonic and cyclonic eddies are investigated to provide insight on the generation and propagation of eddies of varying amplitudes. {T}he largest annual eddy in the {S}omali {C}urrent system corresponds to the {G}reat {W}hirl, for which the year-to-year variability with respect to shape, size, generation, and propagation was examined, as was the development of these characteristics over the {G}reat {W}hirl's lifetime. {P}lain {L}anguage {S}ummary {T}he ocean is full of highly energetic quasi-circular features known as mesoscale eddies having typical radii of 10-100 km. {E}ddies are significant transporters of global heat and ocean characteristics (like salinity and biodiversity). {T}hey are best observed by using satellite observations of fluctuations in sea surface height. {I}n this study, we apply an algorithm to sea surface height satellite data in the northwestern {I}ndian {O}cean to better understand how and where eddies develop during the summer monsoon season, when eddies are strongest. {W}e determined that though more eddies develop in the northern northwestern {I}ndian {O}cean, eddies with largest radii and amplitudes are found along the {S}omali {C}urrent region. {T}hese eddies in the {S}omali {C}urrent are also the most energetic, associated with stronger surface currents. {T}he largest eddy observed in the {S}omali {C}urrent during the summer months is referred to as the {G}reat {W}hirl. {T}his research traces the location where the {G}reat {W}hirl develops and propagates for each year from 1993 to 2014 and shows significant variability.},
