Jupiters great red spot: a free atmospheric vortex?
Science (New York, N.Y.)
|December 28, 1973
Summary
A simple hydrodynamic model explains Jupiter's Great Red Spot, showing it doesn't need special forces to persist. This finding aligns with observations of similar dynamic properties in the Great Red Spot and Jupiter's belts and zones.
Area of Science:
- * Planetary science
- * Fluid dynamics
- * Atmospheric physics
Background:
- * Jupiter's Great Red Spot is a persistent anticyclonic storm.
- * The dynamic mechanisms maintaining the Great Red Spot are not fully understood.
- * Jupiter's atmospheric belts and zones exhibit distinct dynamic properties.
Purpose of the Study:
- * To develop a simple hydrodynamic model for Jupiter's atmosphere.
- * To investigate the self-sustaining mechanisms of the Great Red Spot.
- * To compare the dynamic properties of the Great Red Spot with surrounding atmospheric features.
Main Methods:
- * Development of a basic hydrodynamic model.
- * Derivation of steady-state solutions for atmospheric circulation.
- * Analysis of model outputs to identify key dynamic features.
Main Results:
- * The hydrodynamic model successfully reproduced steady-state solutions.
- * The model demonstrated that the Great Red Spot can be maintained without special forcing mechanisms.
- * Simulated dynamic properties of the Great Red Spot matched observed properties of Jupiter's belts and zones.
Conclusions:
- * A simple hydrodynamic model is sufficient to explain the Great Red Spot's persistence.
- * The Great Red Spot and Jupiter's belts and zones share similar dynamic characteristics.
- * No external forcing is required to maintain the Great Red Spot's circulation.

01:18Kepler's Third Law of Planetary Motion
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. In 1909, he formulated his first two laws based on the observations of his forebears, Nikolaus Copernicus and Tycho Brahe. However, in 1918, he published his third law of planetary motion, which gives a precise mathematical relationship between a planet's average distance from the Sun and the amount of time it takes to revolve around the Sun. It...

In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. He formulated his first two laws based on the observations of his forebears, Nikolaus Copernicus and Tycho Brahe.
Polish astronomer Nikolaus Copernicus put forth a theory that stated a heliocentric model for the solar system. According to this heliocentric theory, all the planets, including Earth, orbit the Sun in circular orbits.

01:29Kepler's Second Law of Planetary Motion
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. His first law states that all planets orbit the Sun in an elliptical orbit, with the Sun at one of the ellipse's foci. Therefore, the distance of a planet from the Sun varies throughout its revolution around the Sun.
While in an elliptical orbit, the total energy of the planet is conserved. Therefore, the planet slows down when it is at apogee and...

01:21Schwarzschild Radius and Event Horizon
No object with a finite mass can travel faster than the speed of light in a vacuum. This fact has an interesting consequence in the domain of extremely high gravitational fields.
The minimum speed required to launch a projectile from the surface of an object to which it is gravitationally bound so that it eventually escapes the object’s gravitational field is called the escape velocity. The escape velocity is independent of the mass of the object. Merging the idea of escape velocity with the...

01:19Magnetic Declination
Magnetic declination is the angle between true north, which aligns with the Earth's rotational axis, and magnetic north, which follows the direction of the Earth's magnetic field. This discrepancy exists because the magnetic poles do not coincide with the geographic poles. The value of magnetic declination depends on the observer's location on Earth and is subject to changes over time due to the dynamic nature of the Earth's magnetic field.The declination is called eastern when magnetic north...
01:23Coriolis Force
An accelerating particle experiences a force equal to the mass multiplied by the acceleration in an inertial frame of reference. Consider a particle in a non-inertial frame of reference, such as a sliding ball on a rotating table. The acceleration of the ball in this rotating reference frame is different than in the intertial frame, which modifies its equation of motion. The fictitious forces acting additionally on a rotating frame of reference alter Newton's Second Law expression. Centripetal...
