We present results from a high-resolution interstellar turbulence simulation and show that it closely reproduces recent Planck measurements. Our model captures the scaling of EE and BB spectra, and the EE/BB ratio in the inertial range. The probability density function of the dust polarization fraction is also consistent with observations. The TE cross-correlation is in broad agreement with the Planck sky. This simulation provides new insights into the physical origins of the observed E/B asymmetry and positive TE signal, facilitating the development of advanced Galactic dust emission models for current and future cosmic microwave background experiments.
