Short summary
Short summary
Comparing weather radar to high resolution LOFAR lightning images, we try to learn about sparkles; small-scale lightning that flash intermittently in the top of intense thunderstorms. Near sparkles, we observe much turbulence and a particular type of ice particles, called graupel. The findings support previous hypotheses regarding the physics of sparkles. Perhaps the combination of graupel and enhanced turbulence is causing electrification in cloud tops and lead to sparkles.
