The Audubon First Guide to Weather is one of the best in the series of Audubon First Guides. The book has a decent number of weather formation listings, including: cumulus congestus, cumulonimbus, cirrus, mesocyclones and quite a few others. Stating that the book is kiddish is quite strange, as this book and its content does not seem geared toward kids particularly at all. It is a fine guide for everyone to use in the field.
There is only one, less recent edition of this guide sold on the market. It is leatherback like the advanced Audubon Guides, so it will come in as a useful reference.
