[날씨 도감] 적란운

A single towering cumulonimbus storm cloud seen from about forty kilometers away across flat farmland at sunset: the cloud rises to the top of the frame and flattens into a wide anvil spreading sideways at the tropopause, its upper edge sharp and lit gold-pink by the low sun while the base is dark blue-grey with a curtain of rain falling below it. The ground and a tiny farmhouse occupy only the bottom 1/8 of the frame, emphasizing the cloud's enormous height. Clear sky around it. No text anywhere.
