Scale & Structure Explorer
The same sky contains structures from crystals to regional light systems.
Scale changes what counts as an edge, layer, object or pattern. This view prevents visual similarity from collapsing physically different structures into one category.
Rainbow arc
arc defined by light, droplets and observer
Fog near the ground
droplet field reducing contrast and visibility
Cirrostratus veil
broad high-level veil
Cumulonimbus storm cloud
deep vertical storm structure
Aurora curtain
luminous emissions organized by magnetospheric interaction
Scale labels are explanatory categories, not a universal meteorological standard.
