Abstract

Abstract

En 中文
• First statistical analysis of long-lived hyperbolic points in the ocean. • Hyperbolic points, not just eddies, control water mass boundaries. • HEPTA provides smoother, more physically consistent eddy trajectories. • Eddy splitting is a topological bifurcation captured by HEPTA.
Keywords:
