Is Weather Chaotic?: Coexistence of Chaos and Order within a Generalized Lorenz Model

Over 50 years since Lorenz’s 1963 study and a follow-up presentation in 1972, the statement “weather is chaotic” has been well accepted. Such a view turns our attention from regularity associated

Accurate detection of large-scale atmospheric tropical waves, such as African easterly waves (AEWs), may help extend lead times for predicting tropical cyclone (TC) genesis. Since observed AEWs have

Recent advances in computational and global modeling technology have provided the potential to improve weather predictions at extended-range scales. In earlier studies by the author and his

A physically extended Lorenz system.

The new six-dimensional Lorenz system is found to self-synchronize, and surprisingly, the transfer of solutions to only one of the variables is needed for self- Synchronization to occur.

Coexistence of Chaotic and Non-chaotic Orbits in a New Nine-Dimensional Lorenz Model

In this study, we present a new nine-dimensional Lorenz model (9DLM) that requires a larger critical value for the Rayleigh parameter (a rc of 679.8) for the onset of chaos, as compared to a rc of

Nonlinear dynamics and complexity in the generalized Lorenz system

Dynamics of magnetized fluids is much more complex than expected from the standard magnetohydrodynamics. Besides chaotic behavior that often appears in nonlinear dynamical systems, hyperchaotic

On periodic solutions in the non-dissipative Lorenz model: the role of the nonlinear feedback loop

Abstract In this study, we discuss the role of the linear heating term and nonlinear terms associated with a non-linear feedback loop in the energy cycle of the three-dimensional (X–Y–Z)

Stability and periodicity of high-order Lorenz–Stenflo equations

In this paper, we derive high-order Lorenz–Stenflo equations with 6 variables and investigate periodic behaviors as well as stability of the equations. The stability of the high-order Lorenz–Stenflo
