  abstract = {{T}he subpolar {N}orth {A}tlantic is a center of variability of ocean properties, wind stress curl, and air-sea exchanges. {O}bservations and hindcast simulations suggest that from the early 1970s to the mid-1990s the subpolar gyre became fresher while the gyre and meridional circulations intensified. {T}his is opposite to the relationship of freshening causing a weakened circulation, most often reproduced by climate models. {T}he authors hypothesize that both these configurations exist but dominate on different time scales: a fresher subpolar gyre when the circulation is more intense, at interannual frequencies (configuration {A}), and a saltier subpolar gyre when the circulation is more intense, at longer periods (configuration {B}). {R}ather than going into the detail of the mechanisms sustaining each configuration, the authors' objective is to identify which configuration dominates and to test whether this depends on frequency, in preindustrial control runs of five climate models from phase 5 of the {C}oupled {M}odel {I}ntercomparison {P}roject ({CMIP}5). {T}o this end, the authors have developed a novel intercomparison method that enables analysis of freshwater budget and circulation changes in a physical perspective that overcomes model specificities. {L}ag correlations and a cross-spectral analysis between freshwater content changes and circulation indices validate the authors' hypothesis, as configuration {A} is only visible at interannual frequencies while configuration {B} is mostly visible at decadal and longer periods, suggesting that the driving role of salinity on the circulation depends on frequency. {O}verall, this analysis underscores the large differences among state-of-the-art climate models in their representations of the {N}orth {A}tlantic freshwater budget.},
