Atmospheric Response to SST in the Eastern Tropical Atlantic in July-August
Résumé
The sea surface temperature (SST) in the Eastern
Tropical Atlantic is characterized by a strong seasonal
cycle. The SST becomes very warm in boreal summer in
the north, off Senegal / Mauritania, while a seasonal cold
tongue takes place in the south, around the Equator.
Along the zonally-extended SST maximum, the
Intertropical Convergence Zone (ITCZ) corresponds to a
region of surface wind convergence and intense
precipitation.
The aim of this study is to document the SST control on
the seasonal evolution of the ITCZ latitude with a
regional atmospheric model (WRF), by manually
removing any SST warming (« Frozen North ») or
cooling (« Frozen South ») from June in the eastern
Tropical Atlantic
