Abstract	The drift wave chaos is investigated using VZSC model [A. A. Vasil'ev, G. M. Zaslavsky, R. Z. Sagdeev, and A. A. Chernikov, Sov. J. Plasma Phys. 16 681(1991)], which is the reduced model of Hasegawa-W...akatani equations with a few degrees of freedom. The statistical properties of chaotic orbits is analyzed using the time correlation function and the power spectrum. The non-Markovian linear stochastic equation for the VZSC model is derived, applying Mori's projection operator method. The applicability of this method is partially confirmed through the comparison with numerical calculation.show more
