原本在空中纤薄层下降并且扩散成薄片状，被命名为层。由大量蓬松积聚集并扩散而成，则命名为层积。

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.

足以形成这些特征风暴——称为铁砧羽上方，或 AACPs——也更有可能产生强龙风、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.
