dc.description.abstract often associated with a temperature inversion. When this occurs, the vertical entrainment brings warmer water from the BL into the mixed layer, causing an increase in the sea surface temperature (SST). We explore the role of this warming mechanism in the maintenance of the western Tropical Atlantic warm pool using the latest Simple Ocean Data Assimilation (SODA) product. During boreal fall and winter, the BL in the northwestern tropical Atlantic reaches a depth of 40 m, due to the combined effects of ITCZ rainfall, Amazon River discharge and the subsurface salinity maximum. An average temperature inversion of 0.1°C is common during these seasons. We estimate that the BL-induced temperature inversion can contribute to a warming of the surface mixed layer at a rate of 0.1°C per month, which accounts for about 30 % of total SST change. This result suggests that in the northwestern tropical Atlantic Ocean the BLs and the associated temperature inversion play an important role in maintaining the warm sea-surface temperature and need to be properly simulated to reduce a cold bias which is common in coupled climate model simulations. -
