Weather Underground has created a whole series of posters celebrating and briefly explaining various weather phenomena. Many of their subjects are beautiful and unusual types of clouds like the lenticular clouds that form over mountains and hole-punch clouds created when supercooled water vapor gets disturbed. They have a few non-cloud phenomena we’ve discussed previously, too, such as dust devils and bizarre, wind-formed snow rollers. I highly encourage you to check out the full collection, which they’ve made available as phone and computer wallpapers as well as posters. Personally, these combine two of my favorite things: fluid dynamics and retro-style nature posters! (Image credit: Weather Underground)
