Textbook, spectacular thunderstorm captured over Tokyo, Japan – August 26, 2018

Every once in a while the weather produces a perfect, textbook phenomenon. And every once in a while, someone captures it perfectly. It happened in Tokyo on August 26: a perfect, textbook thunderstorm.

This thunderstorm displayed a textbook Cumulonimbus capillatus incus shape: a powerful convective updraft and a well-defined anvil at the top. It also produced an impressive ‘bolt from the blue’ lightning bolt: such a bolt starts in the updraft or even in the anvil and strikes out and away from the thunderstorm. This type of lightning bolt can strike up to ~30 km from the thunderstorm; the skies can be blue with hardly a sign of an ongoing thunderstorm, hence the name ‘bolt from the blue’.
