Storms, devils and dust on Mars

Abstract : ose mesoscale-to-microscale meteorological events remains of key interest to betteThe thin veil of suspended dust particles in the Martian atmosphere absorbs incoming sunlight mainly in visible wavelengths (and outgoing infrared radiation), which locally warms the Martian troposphere. Airborne dust is therefore a crucial climate component on Mars which impacts atmospheric circulations at all scales. At the same time, the amount of dust in the atmosphere is controlled through lifting and transport by winds at various scales, mainly through dust storms and dust devils. Hence studying thr understand the Martian climate. In particular, the interplay between lifting, transport, sedimentation is addressed here, along with the possible feedbacks between transported dust and atmospheric dynamics [4]. To that purpose, high-resolution mesoscale modeling [5] and large-eddy simulations [6] are employed.
