A mackerel sky is a common term for clouds made up of rows of cirrocumulus or altocumulus clouds displaying an undulating, rippling pattern similar in appearance to fish scales; this is caused by high altitude atmospheric waves. Other phrases in weather lore take mackerel skies as a sign of changeable weather. Examples include "Mackerel sky, mackerel sky.

dbo:abstract
A mackerel sky is a common term for clouds made up of rows of cirrocumulus or altocumulus clouds displaying an undulating, rippling pattern similar in appearance to fish scales; this is caused by high altitude atmospheric waves. Cirrocumulus appears almost exclusively with cirrus some way ahead of a warm front and is a reliable forecaster that the weather is about to change. When these high clouds progressively invade the sky and the barometric pressure begins to fall, precipitation associated with the disturbance is likely about 6 to 12 hours away. A thickening and lowering of cirrocumulus into middle-étage altostratus or altocumulus is a good sign that the warm front or low front has moved closer and it may start raining within less than six hours. The old rhymes "Mackerel sky, not twenty-four hours dry" and "Mares' tails and mackerel scales make lofty ships to carry low sails" both refer to this long-recognized phenomenon. Other phrases in weather lore take mackerel skies as a sign of changeable weather. Examples include "Mackerel sky, mackerel sky. Never long wet and never long dry", and "A dappled sky, like a painted woman, soon changes its face". It is sometimes known as a buttermilk sky, particularly when in the early cirrocumulus stage, in reference to the clouds' "curdled" appearance. In France it is sometimes called a ciel moutonné (fleecy sky); and in Spain a cielo empedrado (cobbled sky); in Germany it is known as Schäfchenwolken (sheep clouds), and in Italy the clouds are described as a pecorelle (like little sheep). سماء مرقطة Mackerel Sky يستخم هذا المصطلح للدلالة على سماء مغطاة بغيوم من جنس الركام المتوسط، أو السمحاق الركامي، حيث تبدو السماء حينئذ مخططة أو مموجة، لأن تلك الغيوم تأخذ في السماء إما شكلاً عدسياً، أو لوزياً، أو شكل كتل مستديرة تقريباً منتظمة على شكل خطوط، أو تبدو الغيوم بشكل خصل تفصل بينها فواصل خالية من أية غيوم تشاهد منها زرقة السماء، ومثل هذه السماء المرقطة تعرف أيضاً بالسماء المخططة، أو الهيدب.
