DESCRIPTION:Charge processes in planetary atmospheres have always sparked 
 fear and fascination. Lightning is a natural phenomenon with which we – 
 here on Earth – grow up\, but do we understand what it is? If nature is 
 universal\, lightning and charge processes should also occur outside our s
 olar system. Where? Only in planets? Maybe not. The desire to understand t
 he physics of lightning and it’s impact on its environment drives the LE
 AP project. Exciting question touch upon fundamental physics\, numerically
  challenging models\, planetary atmospheres and volcano outbreaks. \n\nI w
 ill present an overview of the LEAP group’s work on how ionisation proce
 sses (thermal\, dust collision\, cosmic rays\, flow-induced) structure  cl
 oud forming atmospheres\, 3D cloud formation modelling in dynamic planetar
 y atmospheres\, and the emergence  of lighting in such chemically and dyna
 mically active atmospheres.\n\n
