At the dentist's, he hovered near the ceiling. As a test pilot, he found secret spaces in cumulus clouds.

在牙科诊所，他盯着天花板发呆。当时，他在积云中发现了秘密空间。

Clouds formed this way are called cumulus clouds, or cumulonimbus clouds, and they usually lead to very heavy rain, often with thunder and lightning.

这样形云被称为积雨云，它们通常会导致大雨，还经常伴有电闪鸣。

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.

原本在高空中纤薄层云下降并且扩散薄片状，被命名为卷层云。由大量蓬松积云聚集并扩散，则命名为层积云。

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，所有云属于三种基本形式之一，霍德华给它们命名为：卷云，来自于拉丁语中卷须或头发，积云，堆积或积累，层云，层叠或片。

He looked at the sky and saw the white cumulus built like friendly piles of ice cream and high above were the thin feathers of the cirrus against the high September sky.

他望望天空，看见一团团白色积云，形状象一堆堆可人心意冰淇淋，在高高上空，高爽九月天空衬托着一团团羽毛般卷云。
