äikesemürinana
Äikesemürinana refers to the sound of thunder in Estonian. It is a common natural phenomenon associated with thunderstorms. The sound is produced by the rapid expansion of air heated by a lightning strike. As lightning travels through the atmosphere, it superheats the air around it to extremely high temperatures, causing it to expand explosively. This rapid expansion creates a shock wave that propagates outwards as sound waves, which we perceive as thunder. The intensity and duration of the thunderclap depend on factors such as the distance of the lightning strike, the type of lightning, and atmospheric conditions. Distant thunder may sound like a low rumble or a continuous roar, while nearby thunder can be a sharp, loud crack or boom. The Estonian word "äike" means thunderstorm, and "mürinana" is the adverbial form of "müdin," meaning rumbling or roaring. Therefore, "äikesemürinana" literally translates to "as a thunderstorm's rumbling." It is a descriptive term used to convey the characteristic sound of thunder.
