violent, thunder, lightening
靂 centers on a sudden, violent atmospheric event: thunder and lightning striking with force. The given meanings all describe the same intense, explosive weather phenomenon.
靂 combines 雨 (rain) with 歷, which likely contributes the sound and the idea of passing through or sequence, suggesting a violent storm passing through with thunder and lightning.
Rain 雨 pours down while the complex lower part 歷 suggests a violent, passing event. Picture a fierce thunderstorm shaking the sky.
For レキ, imagine a violent thunderclap that sounds like a wrecking ball: wreck -> レキ, and the storm wreaks havoc with thunder and lightning.
