Abstract

The nonlinear dynamics of the Lorenz model of general circulation is investigated with the help of analogue electronic circuits. The structure of the attractor is obtained for the various values of the systems parameters. Existence of two external potential terms in the equation leads to some new and interesting features. The data so generated is collected through the use of NI-6009 USB, analogue to digital converter. This was then used to compute the bifurcation pattern, parametric Lyapunov diagrams, Lyapunov exponents. The system clearly showed a non-periodic doubling route to chaos. This is farther substantiated by the simple variation of Lyapunov exponent in bi-parametric space of forcing parameter for the system. These external forcing is actually very important to settle the various issue arising in the long time behavior.
