Gas giants in the Solar System, such as Jupiter, Saturn,
Uranus and Neptune, present large storm cyclones. These
cyclones, storm vortex, are apparently formed by the
differences between temperature, density, rotation speeds of

hemisphere. The dark, elliptically shaped spot (with initial
dimensions of 13,000 × 6,600 km, or 8,100 × 4,100 mi of GDS
was about the same size as Earth, and was similar in general
appearance to Jupiter’s Great Red Spot [1].

a point, moving farther away as it revolves around the point.

The image captured by Voyager 2, the GDS presents a
characteristic that resembles a Cote’s Spiral. Its ellipsoidal
shape is due to the rotation of the different planetary rotation
layers in opposite directions, increasing and compressing the
GDS, from the lower to upper layers of Neptune’s atmosphere

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.

A subtropical cyclone is a weather system that has some characteristics of a tropical cyclone and some characteristics of an extra tropical cyclone. They can form between the equator and the 50 th 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. There are several types of turns, and determining the characteristic equation of which spiral the Extra tropical Cyclone (EC) fits into is the goal of the work. The study demonstrates a double spiral for the extra tropical cyclone; similarly Lindblad (1964) demonstrates a double spiral, to demonstrate the structure of spiral galaxies. Despite the data obtained in the EC that passed through the southern tip of South America west and east of the Falklands Islands, everything indicates that the short occurrence ECs indicate the double spiral structure, but with the structure of a Cote's double spiral.

The characteristic shape of hurricanes, cyclones, typhoons is a spiral. There are several types of turns, and determining the characteristic equation of which spiral the-cyclone bomb‖ (CB) fits into is the goal of the work. In mathematics, a spiral is a curve which emanates from a point, moving farther away as it revolves around the point. An-explosive extratropical cyclone‖ is an atmospheric phenomenon that occurs when there is a very rapid drop in central atmospheric pressure. This phenomenon, with its characteristic of rapidly lowering the pressure in its interior, generates very intense winds and for this reason it is called explosive cyclone, bomb cyclone. It was determined the mathematical equation of the shape of the extratropical cyclone, being in the shape of a spiral called "Cotes's Spiral." In the case of CB, which formed in the south of the Atlantic Ocean, and passed through the south coast of Brazil in July 2020, causing great damages in several cities in the State of Santa Catarina. With gusts recorded of 116 km/h, atmospheric phenomenon-CB hit southern Brazil on June 30, the beginning of winter 2020, causing destruction in its influence over. In five hours the CB traveled a distance of 257.48 km (159.99 miles), at an average speed of 51.496 km/h (31.998 miles/h) 27.81 knots, moved towards ENE, with a low pressure center of 986 mbar, 07:20 UTC, approximate location 35ºS 45ºW, and 5 hours after 12:20 UTC had already grown and had a low pressure center of 972 mbar , approximate location 34ºS 42º30'W.

An "explosive extratropical cyclone" is an atmospheric phenomenon that occurs when there is a very rapid drop in central atmospheric pressure. This phenomenon, with its characteristic of rapidly lowering the pressure in its interior, generates very intense winds and for this reason it is called explosive cyclone, "cyclone bomb" CB. It was determined the mathematical equation of the shape of the extratropical cyclone, being in the shape of a spiral called "Cotes's Spiral." In the case of CB, which formed in the south of the Atlantic Ocean, and passed through the south coast of Brazil in July 2020, causing great damages in several cities in the State of Santa Catarina, Southern Brazil. With gusts recorded of 116 km/h, atmospheric phenomenon-CB hit southern Brazil on June 30, the beginning of winter 2020, causing destruction in its influence over. In five hours, the CB traveled a distance of 257.48 km (159.99 miles), at an average speed of 51.496 km/h (31.998 miles/h)27.81 knots, moved towards ENE, with a low pressure center of 986 mbar, 07:20 UTC, approximate location 35•S 45•W, and 5 hours after 12:20 UTC had already grown and had a low pressure center of 972 mbar, approximate location 34•S 42•30'W. The temperatures of the clouds and the surface near the low-pressure center of the CB. The temperature in the center of the CB is approximately 45•C at 07:20 UTC, July 1, 2020. Five hours later, at 12:20 UTC, in the low-pressure center of the CB, the temperature varies from 45•C to-30•C, indicating that the CB increases in size and further tapers its core, sucking a great amount of steam to high altitudes of water where it condenses quickly.
