Shown above is the intriguing skyscape I observed from my home in Paris, France, on the afternoon of January 28, 2020. During much of the day, the weather was quite agitated – gusty winds and threatening skies. Higher up, clouds that appear to be cirrus, exhibit glaciation. When ice crystals fall from cirrus clouds, they most always sublimate before reaching the surface. That’s the top of the Eiffel Tower at bottom.
