Perhaps these are treating 'eng cloud not as an object but as a mass noun akin to “grass” or “wool”. I would be willing to think of it as working like “rock”, which can be either a countable thing or a substance (e.g. a “rock wall”).

Or perhaps it’s just an error in canon.

Shouldn't these sentences have the prefix *lu-*, since we are speaking of "clouds" (plural)? Or is it a "weather exception"?
