Cyclogenesis over the Southern Ocean
E. Linacre and B. Geerts
Cloud vortices observed by satellite over the Southern Ocean indicate three main areas where lows originate (1). These are
- over the south Atlantic, east of South America, near Enderby Island on the coast of Antarctica at about 50 °
E, and further east,
- from Kerguelen Island at about 70 °
E to South Australia (with cyclolysis near Adelieland at 140 °
E on the coast of Antarctica), and
- in the central Pacific (with cyclolysis in the Bellingsen Sea at 90 °
W off the Antarctic coast).
