Comparison of the ocean situation in 2009-2010 and the situation today where the winters are unusually cold and the NAO index negative.

Some warm events in the South Atlantic Ocean have been named Benguela Niños, because of the similarity to the El Niño phenomenon in the Pacific Ocean (ENSO).

Currents and eddies are numerous in the Levantine basin. They shift or disappear according the seasons.

The Gulf Stream is a turbulent western boundary current with strong variations caused by an intense eddying. By representing the SLA variance, areas with high variability are shown.

The Solomon Sea is a key area where currents redistribute water from the subtropics to the equator. The LAS is used to highlight its complex ocean circulation and its variations.

The South China Sea is a large semi-enclosed sea where the seasonal circulation is driven by the asiatic monsoon system. Numerous anticyclonic and cyclonic gyres are observed with the LAS.

The LAS is used to map the typical eddies (called swoddies) of the Navidad current. For this 2009-2010 winter, it is relatively well marked, correlated with a negative NAO index.

Along the Somali coast, the seasonal circulation changes drastically with a spectacular reverse in the Somali current.
