Light Pillars, 22° Halos, Tangent Arcs, Bottlinger’s rings, Parry Arcs, and Circumzenithal Arcs, and More! In our two previous articles, we discovered diamond dust and sun dogs. While these phenomena are righteous on their own, they are singular manifestations of a larger class of optical splendors. They both arise thanks to ice crystals in the […]
Sun Dogs “two mock suns rose with the sun and followed it all through the day until sunset.” – Aristotle, Meteorology In our previous examination, we learned how it’s possible for snowfall to occur on cloudless days in the form of diamond dust.

Diamond Dust Have you ever found yourself outside on a cold, clear, still day and noticed a snowfall? No clouds above to produce the precipitation; no gusts to blow up fallen snow.

Derechos I think most people are familiar with tornadoes, hurricanes, and blizzards, all storms associated with ferocious winds.
