  abstract = {{T}his paper presents the major characteristics of the {I}nstitut {P}ierre {S}imon {L}aplace ({IPSL}) coupled ocean-atmosphere general circulation model. {T}he model components and the coupling methodology are described, as well as the main characteristics of the climatology and interannual variability. {T}he model results of the standard version used for {IPCC} climate projections, and for intercomparison projects like the {P}aleoclimate {M}odeling {I}ntercomparison {P}roject ({PMIP} 2) are compared to those with a higher resolution in the atmosphere. {A} focus on the {N}orth {A}tlantic and on the tropics is used to address the impact of the atmosphere resolution on processes and feedbacks. {I}n the {N}orth {A}tlantic, the resolution change leads to an improved representation of the storm-tracks and the {N}orth {A}tlantic oscillation. {T}he better representation of the wind structure increases the northward salt transports, the deep-water formation and the {A}tlantic meridional overturning circulation. {I}n the tropics, the ocean-atmosphere dynamical coupling, or {B}jerknes feedback, improves with the resolution. {T}he amplitude of {ENSO} ({E}l {N}io-{S}outhern oscillation) consequently increases, as the damping processes are left unchanged.},
