The beauty of Howard's system was that the basic components could be freely recombined to describe every shape and size of passing cloud--stratocumulus, cirrostratus, cumulocongestus, and so on.

霍华德体系妙处在于，这些基本成分可以自由组合，描述天空中飘过每种形状、每种大小云——层积云、卷层云、积雨云等等。

Now, let's look at the five most basic, we'll start with cumulus which is a low cloud with a white puffy appearance and most often composed of water droplets.

现在，让我们来看看五种最基本，我们先从积云开始，积云是种白色蓬松低云层，通常由水滴组成。

If this is intense, and it's unrelenting, and it continues to build, That cumulus cloud, which is just white with sunlight moving through it, it becomes less white.
