  abstract = {{T}he summer {S}outh {V}ietnam {U}pwelling ({SVU}) is a major component of the {S}outh {C}hina {S}ea circulation where it also influences ecosystems. {H}ere we revisit the existing knowledge of the {SVU} interannual variability. {B}ased on a set of 15-year eddy-resolving sensitivity simulations, we quantify the respective contributions from different factors (atmospheric, river, and oceanic forcings; ocean intrinsic variability; and {E}l {N}ino {S}outhern {O}scillation) to this interannual variability and explore the underlying mechanisms. {O}ur sea surface temperature upwelling indices allow us to quantify the strong {SVU} interannual variability in terms of strength and spatial distribution. {S}trong {SVU} years are offshore dominant with {SVU} centers located within 11-12 degrees {N} and 110-112 degrees {E}, whereas weak {SVU} years are coastal dominant with {SVU} centers located near the coast and spanning a larger 10-14 degrees {N} latitude range. {O}ur study confirms the leading influence of the summer wind and further reveals that coastal {SVU} variability is related to the variability of the eastward jet that develops from the coast, whereas offshore {SVU} variability is strongly driven by the spatiotemporal collocation of wind stress curl with cyclonic eddies. {O}cean intrinsic variability, and to a lesser extent perturbations induced by river discharge and lateral oceanic conditions, strongly triggers interannual variability of background eddy circulation, thus of the {SVU}. {E}l {N}ino {S}outhern {O}scillation influences the {SVU} mainly through its direct influence on summer winds.},
