What does *they* refer to?

When the waves are large and follow close upon each other as they* *do under storm conditions, the berm is worn down and the bar builds up.

In the above sentence, I think do* refers to "follow close upon wach other", then what does *they refer to? Is it "the waves"?

Thank you so much.
