Distant Thunderstorm

Thunder is the sound of air explosively heated by a lightning channel. Close by it is a crack; at distance the same event arrives as a long roll, because the sound reaches you from different parts of a kilometres-long channel at different times, and because air and terrain strip away the high frequencies on the way.

That distance filtering is what makes far-off thunder comfortable rather than startling: what remains is mostly low-frequency energy with slow envelopes.

Rapid thermal expansion of air along a lightning channel, then propagation, refraction and absorption across several kilometres.

Commonly heard: Anywhere with convective storm activity - most frequently in humid continental and tropical regions during the warm season.

Through the seasons: Peaks in late spring and summer afternoons and evenings when surface heating drives convection.

Sparse, very high dynamic range events layered over continuous rain. Long decay tails; ground and cloud reflections extend the roll.

Frequency profile: Dominated by low frequency energy, often with substantial content below the range of small speakers. Nearby strikes add a sharp broadband transient.

Creative work

Thunder rolls make natural transitional swells between sections of an ambient piece.

Relaxation

Best when the strikes are distant and sparse; frequent close cracks defeat the purpose.

Meditation

Use sparingly - the irregular events pull attention.

Focus

Less suitable than plain rain, because unpredictable loud events interrupt concentration.

Sleep

Some people find it deeply comforting; others are woken by the peaks. Keep the dynamic range compressed and the level low.

• Distant summer thunderstorm rolling across open fields, steady rain, deep sub-bass rumbles, warm analogue pads
• Slow cinematic ambient with far-off thunder, wet wind, low strings and a single sustained note

• Counting seconds between flash and thunder works because sound travels roughly one kilometre every three seconds - about a mile every five.
• Thunder is rarely heard more than about 15 km away; beyond that, atmospheric refraction bends the sound upward, over your head.
