abstract = "The thermodynamics of the seasonal evolution of the Southwestern
Tropical Atlantic Warm Pool (hereafter SWTAWP), which is delimited
by the 28 °C isotherm, is investigated using the Regional Ocean
Modeling System (ROMS). Results indicate that the net heat flux is
responsible for the appearance and extinction of the SWTAWP. From
March to May, the SWTAWP attains its maximum development and
sometimes merges with equatorial warm waters towards the African
continent, whose development follows the same period. Along the
equator, the combination of oceanic terms (i.e., advection and
diffusion) is important to promote the separation when it occurs
of equatorial warm waters from southwestern tropical waters, which
develops off the Brazilian coast. An analysis of the relative
contribution of the temperature tendency terms of the mixed layer
(ML) heat budget over the appearance, development and extinction
of the SWTAWP is also done. The most important term for warming
and cooling inside of the ML is the net heat flux at the sea
surface. The ML is heated by the atmosphere between October and
April, whereas the upper ocean cools down between May and
September. The highest heat content values occur during the
lower-temperature period (August to October), which is linked to
the deepening of the ML during this time period. The horizontal
advection along the equator is important, particularly at the
eastern domain, which is influenced by the cold tongue. In this
area, the vertical diffusive term is also significant; however, it
presents values near zero outside the equator. These results
contribute to a better understanding of the behavior of the heat
budget within the tropical Atlantic, as previous studies over this
region focused along the equator only.",
