AB: Magnetic and plasma fluctuations are ubiquitous in a space plasma. In particular, those found in the earth's foreshock region have order of unity normalized magnetic field amplitude, so that it is worthwhile looking into correlations among the fluctuations not only at the leading order but also at the second order. By performing hybrid numerical simulations, we evaluate the correlation between the magnetic and the density fluctuations at the second order, and show that this correlation is an important parameter to characterize the turbulence. Possible application of the present analysis to spacecraft obtained data will be discussed.
