Abstract

This study focused on the concept of fractal structure in plasma turbulence. This phenomenon is a multifaceted action of charged particles and electromagnetic field and is an unstable state of fluid. Therefore, it occurs as a consequence of the collective character of mutual interactions of charged particles in the plasma. Using the rescaled range analysis approach, we estimated the fractal dimension of plasma turbulence data at the Pakistan atmospheric region to the observed dynamical behavior. The estimated value of fractal dimension of plasma turbulence was approximately 1.8; the plasma turbulence being greater than 1.5, the behavior was anti-persistent, i.e., indicating a deceasing trend in plasma turbulence. This study revealed that the nature of plasma turbulence was randomness and intermittence. In summary, it was observed that fractal analysis is helpful to examine the persistent, anti-persistent and Brownian nature for long-range behavior of chaotic systems.
