Night, Night from Mamma

Early evening is a great time for spotting mamma clouds. Named after the Latin for an ‘udder’, mamma are well-defined pouches hanging from the underside of a cloud layer. They can appear on several of the ten main cloud types but the best ones are always found suspended from large Cumulonimbus storm clouds. Mamma appear to the rear of storms, on the underside of the huge cloud canopies that spread out in their upper reaches. The day’s end is often when storms that have built up through the afternoon eventually reach their peak. On roll the storms, causing havoc and destruction elsewhere. In their wake, come the calming Mamma clouds. Lit by the warm glow of the setting Sun, they whisper at the bedside for us not to worry. Everything will be OK in the morning. Tomorrow is another day.

    Very nice! Thank you, and thank you Pablo Barrios, for this superb image – surely a candidate for the definitive photo of mamma clouds? (Indeed, why not use it for your next book?) Thank you too for your wonderful lyrical explanatory text. (Apart from anything else, I was glad to know the reason for what looks almost like an artificial red cast!)
