abstract = "The ocean temperatures and zonal currents at the equatorial
Atlantic simulated by an improved version of the Brazilian earth
system model (BESM), with changes in the cloud cover scheme and
optical properties of the atmospheric component, are analyzed and
compared to those obtained from a previous version of BESM and
also from other seven selected CMIP5 models. It is shown that this
updated version of BESM, despite some persistent biases, more
accurately represents the surface temperature variation at the
Equator and the equatorial thermocline eastwest slope. These
improvements are associated to a more realistic seasonal cycle
achieved for the Atlantic equatorial undercurrent, as well as sea
surface temperatures and zonal wind stress. The better simulation
of the equatorial undercurrent is, in its turn, credited to a more
realistic representation of the surface wind position and strength
at the tropical Atlantic by the coupled model.With many of the
systematic errors noticed in the previous version of the model
alleviated, this version of BESM can be considered as a useful
tool for modelers involved in Atlantic variability studies.",
