Our concept of severe weather

  What do we mean by “Severe Weather”?


We aim to describe a particular kind of weather facts: those that we could call “extreme”, or at least go beyond what we call normal. Then, it is important that we state a definition for those facts. We have created a comprehensive list of codes to name all the events. In the “Collaborators” section, you will find further information about those codes, as well as some directions to write your own Chasing Reports.
