Abstract: We present a numerical simulator of meteor forward-scatter echoes based on a deforming ionized trail and atmospheric wind shear. The model combines trail skew with fundamental, second- and third-harmonic velocity components to reproduce the observed Doppler evolution. Synthetic spectrograms and audio echoes are generated while the trail geometry is visualized interactively. The results show good qualitative agreement with observational data, making the simulator a useful tool for understanding the characteristic C- and ϵ-shaped meteor echoes and their relation to atmospheric dynamics.
