  abstract = {{I}n this paper, the sensitivity of {A}tmospheric and {O}ceanic {C}oupled {M}odels ({AOCM}s) to the coupling method is investigated. {W}e propose the adaptation of a {S}chwarz-like domain decomposition method to {AOCM}s. {W}e show that the iterative process of the method ensures consistency of the coupled solution across the air-sea interface, contrarily to usual 	extit{ad-hoc} algorithmic approaches. {T}he latter are equivalent to only one iteration of a {S}chwarz-like iterative method, which does not provide a converged state. {I}t is generally assumed that this lack of consistency does not affect significantly the physical properties of the solution. {T}he relevancy of this statement is first assessed in a simplified problem, then in the realistic application of a mesoscale atmospheric model ({WRF}) coupled with a regional oceanic model ({ROMS}) to simulate the genesis and propagation of tropical cyclone {E}rica. {S}ensitivity tests to the coupling method are carried out in an ensemble approach.{W}e show that with a mathematically consistent coupling the spread of the ensemble is reduced,suggesting that there is room for further improvements in the formulation of {AOCM}s at a mathematicaland numerical level.},
