In sharply defined rainbows, a set of narrow coloured bands can often be found repeating on the inside of the primary bow. Called supernumerary bows, they add an extra-special dimension to the display and are produced by diffraction as light waves cross each other exiting the raindrops, as seen here over Amsterdam, Netherlands.

As the plane began its descent, Rachel noticed a cloud that resembled a small, errant, and lonely tornado. This took place towards the end of a flight from Vancouver, British Columbia to Ottawa, Ontario, Canada.

In The Cloudspotter’s Guide I found this is a Cirrocumulus lacunosus, “is a lattice of cloud around distinct holes. Being so high up, this loose honeycomb formation is finer that the lacunosus varieties of Altocumulus and Stratocumulus”. It does look like the puffs in rows of “cloud streets” from 35,000 ft. Joanne.
