The actualization of the Catalan weather glossary as a scientific tool for communicating atmospheric sciences: an analysis based on the diversity index of Shannon and the complex network theory.

The actualization of the Catalan meteorological glossary concluded in 2024. It has been based based on the original work of Fontserè (1948), a piooner work for disseminating weather in catalan language. The result has been an online terminology, including all new meteorological and climatological new terms that have been appeared from 1948 until now, related with current topics like climate change, climatic crisis, numerical simulation or teledetection, among other. They have been grouped in eleven meteorological families, from the original 840 terms to the near 2300 currently. The presentation aims to show two main goals. Firstly, to show the new online web glossary, which includes new and current terms not published yet in classical glossaries of meteorology, and also includes pictures for all those terms linked to the clouds and meteorological phenomena. The final result is an excellent tool for communicating the atmospheric science among different targets (media, scholar, ...). Secondly, to show the results of two pioneer analysis that have been done with the terms included in the glossary. The first has consisted in applying the diversity Shannon index to the whole terms grouped in the eleven meteorological families, to define a new index to quantify how the meteorological terms spread out in Catalan language, and comparing the original glossary of 1948 with the current one. This diversity Shannon index of terms is proposed as a new parameter to define any meteorological glossary, which can account how a certain language spread their terms along the 11 meteorological families. The second study has consisted in apply complex network theory to quantify and analyze the interconnected terms of the glossary.
