A solar terminator wave (TW) is found in high-resolution general circulation model (GCM) simulations of Mars' atmosphere. In the horizontal plane at 160 km the wave fronts precede the westward-moving dusk terminator, exhibit a horizontal wavelength of order 15°-30° or 900-1800km, and are oriented about 10°-30° with respect to the terminator. The disturbance originates in the lower atmosphere due to dust insolation absorption, propagates upward with an effective vertical wavelength of order 60 km, and increases in amplitude as the dust extends further away from the surface. The TW density amplitudes for low and elevated dust layers (both with opacities = 1.0) are of order ± 15-20% and ± 30% at 160 km, which are sufficiently large to pose a concern for aerobraking operations. Temperature and wind perturbations for the former case are of order ± 10-20 K and ± 30-75 m/s. The Mars TW shares many common features with a TW recently observed in Earth's thermosphere and simulated with a GCM.
