Sastrugi Wind Carvings and Drifting Snow Vortices

Full prompt

An expansive 4:3 landscape desktop wallpaper capturing aerodynamic sastrugi snow formations across a high-Arctic plateau. Crisp, wind-sculpted ridges of hard-packed snow sweep diagonally across the lower foreground, their sharp crests illuminated in radiant warm alabaster by low-angled polar sunlight. Swirling ribbons of loose powder snow drift between the frozen troughs, casting cool cobalt blue shadows that ground the scene. The upper half opens into a serene, pale twilight sky shrouded in faint atmospheric haze, providing ample quiet area for desktop computer icons. The balanced medium-format perspective captures frozen velocity and vast subpolar silence while maintaining an uncluttered, comfortable screen environment.
