"Thundery" is the sixth in the series of weather picture books "Weather Tales" - a picture book on the topic of meteorology. Their goal is to educate - bring some frequently mentioned meteorological terms closer to children, so that they can later better understand and benefit from meteorological information, especially in this era of increasingly obvious climate changes and global warming.

The topic of "Thundery" is lightning, lightning flash, thunder and thunderbolt - where, when and how these light and sound phenomena occur, which of them are dangerous and which are only frightening, how to behave during their duration, what lightning rods are, what the longest duration of one lightning flash is...

"Thundery" is not only a picture story, but also has rebuses, anagrams, crosswords, and even a colouring book.
