Abstract: | Space plasmas are dominated by waves, instabilities and turbulence. Dynamical systems approach offers powerful mathematical
and computational techniques to probe the origin and nature of space environment turbulence. Using the nonlinear dynamics
tools such as the bifurcation diagram and Poincaré maps, we study the transition from order to chaos, from weak to strong
chaos, and the destruction of a chaotic attractor. The characterization of the complex system dynamics of the space environment,
such as the Alfvén turbulence, can improve the capability of monitoring Sun-Earth connections and prediction of space weather.
