Aren't thermals a diurnal phenomenon caused by the heat of the sun? Don't thermals fade and die at night? Dragongliders would have to hunt by day.A dragon would be large, but not as large as those in myth - myths tend to exaggerate size, after all. I'm imagining them as something roughly the size of a horse, with a large wing span that could fold up. They would be quadrepeds, with the "wings" being flaps underneath the forearms, similar to that of a bat's. These wings would not allow flight, but perhaps gliding - leading to dragons living in mountainous and hilly-cliff areas, especially areas with thermals that could raise the dragons hundreds of feet in the air. Because of their gliding ability, they'd be excellent climbers.

Because they are gliders and are rather large, I see dragons as being nocturnal creatures -

I'm actually a little confused about the question. Are you asking what we could infer about "real" dragons (presumably now extinct) based on the myths humans have made about them, sort of a speculative anthropology and paleontology?
That would be interesting to think about given the differing roles eastern and western dragons take in their respective mythologies. Just a simple-minded one, for example: while western dragons I'm pretty sure would be carnivorous, would eastern dragons also be? (I really don't know; I'm not familiar enough with the mythology.) I also get the impression their intelligence levels would be different, which would have ramifications for how they interact with people. And if the two dragons actually were the same creature, why are they perceived so differently by the two culture groups?
...reasons for different descriptions by different human cultures?
Pathfinder SRD said:Half-dragons are only rarely the result of dragons mating with other creatures—most are the result of strange magical experiments.
There was a docufiction from the animal planet about this a few years ago.
