The work is based on the analysis of an extratropical cyclone that passed west of the South Georgia Islands in late winter 2025. This extratropical cyclone (hereinafter referred to as Georgia) and others that commonly pass through the South Atlantic Ocean have a strong influence on the region's climate, with winds above 80 km/h. The Georgia cyclone that formed south southeast, of South Georgia Island. It traveled 74 km in 7.5h towards the north-northwest, when it was 320 km of core from South Georgia Island. It moved at an average speed of 9.81 km/h (6.1 mi/h). The highlighted turbulent cyclonic vortex exhibits two Cote’s curves. The shape of Georgia and other cyclones that hit this region has already been well characterized, having the shape of a Cote's spiral curve, also similar to spiral galaxie, Gobato et al. (2020-24) such as Messier 77 and the Great Dark Spot (GDS) of Neptune.
