Received: 08 Mar 2012 – Published in Ocean Sci. Discuss.: 28 Mar 2012Abstract. A set of meteorological instruments was added to an oceanographic cruise
crossing the Southern Ocean from Cape Town to 57°33' S during the summer
of 2008. The Cape Cauldron, the Subtropical, Subantarctic, Polar and southern
Antarctic Circumpolar current fronts were successively crossed. The recorded
data permitted to derive the exchange of momentum, heat and water vapour at
the ocean-atmosphere interface. A set of 38 radiosonde releases complemented
the dataset. The marine atmospheric boundary layer characteristics and
air-sea interaction when the ship crossed the fronts and eddies are
Revised: 14 Sep 2012 – Accepted: 29 Sep 2012 – Published: 23 Nov 2012
The specific role of the atmospheric synoptic systems advection on the
air-sea interaction over these regions is highlighted.
Additionally, the Subantarctic front mesoscale variability induced an
anticyclonic eddy considered as part of the Subantarctic front. The specific
influence of this Agulhas ring on the aloft atmosphere is also presented.
