The first one are whale song, slowed down and reduced in pitch.
The second one sounds like feedback.
The third one is caused by the sound reverberating through the cold dense air. It sounds like traffic over a roadway. Sound travels farther in cold air than it does in warm air due to the density of the air.
The fourth one sounds like construction, considering there is a lot of that going on in Glasgow down by Central station, that wouldn't suprise me that people hear it. But it sounds like metal/steel being moved.
The fifth one sounds like some kind of saw, though the sound has been modified somewhat. Again, in cold weather sound will travel further than expected.
The sixth one sounds like a bell rung and slowed down extremely slow and reduced in pitch.
The seventh one sounds like AC line noise, though again slowed down.
The eigth one sounds like an instrument of some sort, possibly a piano.
The nineth one I'm assume is the heavy equipment in the parking lot.
The tenth one sounds like an air horn reverberating through the cold air.
The eleventh is whale sounds.
The twelveth might be whale sounds, or an air horn slowed down. It's strange that no one on the ground is responding to it. So it's either post-production or it's something people would naturally hear, just altered.
