New model explaining why Jupiter’s mysterious Great Red Spot has not disappeared
Jupiter’s Great Red Spot is one of the solar system’s most mysterious landmarks. Based on what scientists understand about fluid dynamics, this massive storm – which is big enough to engulf the Earth two or three times over – should have disappeared centuries ago.
Pedram Hassanzadeh, a postdoctoral fellow at Harvard University, and Philip Marcus, a professor of fluid dynamics at the University of California, Berkeley, think they can explain why. Their work, which Hassanzadeh will present at the annual meeting of the American Physical Society’s Division of Fluid Dynamics in Pittsburgh on November 25, also provides insight into persistent ocean eddies and vortices that contribute to star and planet formation.
