A notable storm system in an area that Santiago described as formerly being desolate without any vegetation. Over the past few decades, Chinese forest rangers planted trees and gradually nurtured the environment back to life. Today, there are endless stretches of lush forest farms, as seen here near the Saibangba Forest Farm, Weichang County, Chengde City, Hebei Province, China.

Nacreous clouds, forming at altitudes of 15-25 km (10–20 miles), up in the stratosphere, at temperatures of around -85˚C (-121˚F), these clouds show beautiful iridescent pastel hues as they scatter the light from the Sun when it is just below the horizon. Sometimes called ‘mother-of-pearl clouds’, their tiny, uniform ice crystals are very good at diffracting sunlight. This classic example was spotted in December of a prior year, over Nottingham Castle, Nottingham, England.
