On Saturday, 12 November 2022, South Australia, including the whole Adelaide region, experienced an uncharacteristic extended storm of unusual intensity. Several storm fronts, arriving from the NW over St Vincent's Gulf, hit Adelaide and the Fleurieu Peninsula. The storm has been described as "one of the strongest thunderstorms in recent memory",* causing flash flooding, wind gusts exceeding 100 km/h that tore down huge gum trees (many of which crushed houses, cars, and electricity lines), as well as flattening giant electricity pylons, leaving around a hundred thousand people without power.
This recording, made in the Adelaide Hills (near Norton Summit), captures a sample of the first and mildest storm wavefront that day. (The recording begins at 10:30 in the morning. This abridged version selects two excerpts from the longer recording, chosen because of the poignant presence of bird calls audible between the peals of thunder. The highlighted parts of the spectrogram in the track image indicate the passages from the longer recording that were selected for this abridged version.) The microphones sheltered from the fairly light rain underneath a 'sweet pittosporum' or 'native daphne' tree (Pittosporum undulatum), native to southeastern Australia, but a 'declared plant' in South Australia ('a woody weed invading native local vegetation', due to widespread ornamental planting).
Travelling farther south immediately after this recording, I was able to intercept the next two storm wavefronts, which were far more intense. Although the storm was utterly awesome and spectacular (lightning bolts plunging into fields, exploding thunder tearing the atmosphere apart), it was impossible to find any spot from which to record the storm, because it brought with it an abundant lashing downpour of rain and wild tree-tossing winds. All the shelters in the state forests had iron rooves: the rain battering the rooves was deafening, drowning out even the peals of thunder.
In the end, I could only just sit and experience it. Which, after all, is the very best thing to do, with Nature. (Most of the time, at least. Not recommended when it gets this violent. Although I have to say that this was truly a very beautiful and awe-inspiring experience; and, personally, I'm very glad to have been out there to witness it. I'm also contemplating possible recording solutions, in case this ever happens again... Enraptured by thunderstorms as a spatial music of nature. All that I have said, here, is the simple truth.)
