Double Spiral Cote's Galaxies NGC 1566 and the Southern Pinwheel, and Cyclone in the South Sandwich Islands

The work is focused on the comparative analysis of the shape of spiral galaxies and the subtropical cyclone that formed north of Georgia Island and passed north of the South Sandwich Islands, in the South Atlantic Ocean. Subtropical cyclones with double spirals appear to be common in these areas of the South Atlantic. A subtropical cyclone is a weather system that has some characteristics of a tropical cyclone and some characteristics of an extratropical cyclone. They can form between the equator and the 50th parallel. In mathematics, a spiral is a curve, which emanates from a point, moving farther away as it revolves around the point. The characteristic shape of hurricanes, cyclones, typhoons is a spiral. The characteristic equation of which spiral the Extratropical Cyclone (EC) its double spiral shape, whose mathematical equation has already been defined as Cote’s spiral, Gobato et al. (2022) and similarly Lindblad (1964) show shape of double spiral galaxies, already studied among others is discussed here. Analyzed the spiral galaxy M83 also known as the Southern Pinwheel, this galaxy is located 15 million light-years away from Earth in the constellation Hydra, and NGC 1566 sometimes known as the Spanish Dancer, is an intermediate spiral galaxy in the constellation Dorado, positioned about 3.5º to the south of the star Gamma Doradus.
