Cirrus is a kind of cloud, very high in the sky, light and thin, shaped like feathers or wisps of white hair. Up there the air is so cold that the cloud is made of ice, not of water drops.

Cirrus捲雲is a kind of cloud是一種雲，very high in the sky位置非常高，light and thin輕輕薄薄的，shaped like feathers or wisps of white hair形狀像羽毛或一絲絲的白髮。Up there那麼高的地方，the air is so cold空氣冷到，that the cloud is made of ice讓這種雲是由冰做成的，not of water drops而不是水滴。

Cirrus by itself does not usually mean a downpour over your head. Though actually, when more and more of it spreads across a clear sky, it can be an early sign that the weather is about to change.

Cirrus by itself光是捲雲本身，does not usually mean a downpour over your head通常不代表你頭頂上會下大雨。Though actually不過事實上，when more and more of it spreads across a clear sky當它在晴朗的天空中越擴散越多，it can be an early sign它可能就是個早期訊號，that the weather is about to change代表天氣快要變了。

The name is a learned borrowing from Latin cirrus, “a curl, a fringe, a horse’s forelock.” A British chemist and cloud-watcher, Luke Howard, gave this cloud type its name in 1803; he wanted clouds to have clear Latin names, the way plants do, and scientists still use his names.

The careful plural is cirri, also from Latin, though people also say cirrus clouds. Latin cirrus can also mean a curl or tendril on a plant or animal, but the sense here is the high feather-cloud.
