Unafraid of the ocean's power, they blithely reach out their cirri to capture tiny plankton.

它们毫不畏惧海水的力量，悠然自得地伸出蔓足，以捕食水中的浮游生物为生。

The highest flying clouds here are cirrus clouds which can be found at altitudes of 20,000 to 40,000 feet.

这里最的飞行云是卷云，可以2万到4万英尺的度找到。

Slender sheaves of cirrus clouds were followed on the horizon by layers of nimbocumulus. Other low clouds fled swiftly.

天际边一层层散开的卷云的后面，紧随团团乌云，还有一些低云飞快地掠过。

On any given day odds are you'll see several contrails, some slowly spreading out to form high, cirrus clouds.

每天我们都有机会看到航迹云，有些会慢慢散开形成空卷云。

AACPs are the wispy, cirrus clouds that form near the overshooting tops.

AACP是超冲顶部附近形成的纤细卷云。

A high, whispy cirrus cloud that descended and spread into a sheet was named cirrostratus, while groups of fluffy cumulus clouds that joined up and spread were named stratocumulus.

原空中的纤薄的层云下降并且扩散成薄片状，被命名为卷层云。由大量蓬松的积云聚集并扩散而成的，则命名为层积云。

Storms that were strong enough to make these features--called above anvil cirrus plumes, or AACPs-- were also more likely to have severe tornadoes, large hail, and high winds.

足以形成这些特征的风暴——称为铁砧卷云羽上方，或 AACPs——也更有可能产生强龙卷风、大冰雹和大风。

In fact, all clouds belong to one of three principle types to which Howard gave the names: cirrus, Latin for tendril or hair, cumulus, heap or pile, and stratus, layer or sheet.

实际上，所有的云属于三种基形式之一，霍德华给它们命名为：卷云，来自于拉丁语中的卷须或头发，积云，堆积或积累，层云，层叠或片。

His tail floats now behind him, now above him, level or gracefully curled like a wisp of cirrus cloud, every hair in its place, clean and shining and radiant as thistle-down in spite of rough, gummy work.

像一缕卷云一样水平或优雅地卷曲， 每一根毛发都各就各位， 干净、闪亮， 尽管经过了粗糙、粘稠的工作， 但仍像蓟绒一样闪闪发光。
