Moderate rain under near-constant lightning, with thunder that rolls rather than cracks. Strike distance is modelled properly, so the sound arrives after the flash.
Lightning turned most of the way up over a moderate rainfall. The point of this scene is the thunder, so everything else stays out of its way.
Each strike is placed at a distance and the audio is delayed by the real travel time — sound covers about 343 metres a second, so a strike three kilometres out is heard some nine seconds after you see it. Air absorbs high frequencies far faster than low ones, so distance also decides the character: a close strike is a bright violent crack, a far one arrives as pure low rumble with all its top end stripped away.
The roll is not one decay curve. A lightning channel is kilometres long, so sound from its near end reaches you well before sound from its far end, and the peal is built from overlapping swells at irregular intervals to match. It is why distant thunder rumbles for so much longer than close thunder.
Every control stays adjustable once the scene has loaded, and the live-weather toggle hands it back to drifting on its own.
