  abstract = {{A} new global climatology of the barrier layer ({BL}) thickness based on the analysis of instantaneous temperature and salinity profiles was presented in the first part of this paper. {I}t is used here to revisit the mean properties of the phenomenon in the tropics. {C}onsistent with previous studies, thick and persistent {BL}s are detected in the deep tropics of each ocean. {T}heir formation involves various mechanisms such as intense precipitations, oceanic circulation, wind seasonality, and river runoff, in relation with the specific geography and climatology of each basin. {T}he weak seasonal cycle of the {BL} in the equatorial {P}acific is analyzed in particular. {T}hick {BL}s are also detected in winter on the equatorial flank of each of the subtropical salinity maxima. {T}hey are due to the specific salinity stratification in this area and to the seasonal homogenization of temperature over the vertical under the action of atmospheric heat fluxes. {T}hick {BL}s in the western tropical {A}tlantic that are partly associated with important vertical temperature inversions are furthermore identified and described. {M}ore generally, agreement of the {BL}s mean properties in these areas with previous literature confirms the robustness of the features and validates this new product that uses most available data including the most recent ones issued from the {ARGO} floats.},
