What starts off looking like a normal cloud is actually a cloud created around a large UFO. This particular cloud is being made by a smaller UFO built for the job, like small worker drones around a main craft. The UFO produces the clouds to hide the craft. There are many reasons to hide it even though it may be cloaked...if its glowing in any way, they always will create clouds around it to hide the glow. Also when you see long cloud tunnels side by side, that is how they hide the glowing ships when moving across the planet from base to base.
