DESCRIPTION:EPSSI Seminar:\nObservations of the Microscale Features of Thun
 derstorms and their Relationship to Lightning-produced NOx\n\nOur understan
 ding of snowflakes is biased toward regions where they can be easily observ
 ed.   For example\, when modern airborne imaging instruments are brought to
  the upper regions of thunderstorms\, we observe ice particle shapes that a
 re not found in typical textbooks on the subject.   In particular\, chains 
 of frozen droplets are found in Midwestern storms\, which are likely formed
  by electrical forces acting on frozen droplets in the upper regions of the
  storm.   These same electrical forces are responsible for lightning\, whic
 h produces Nitrogen Oxides (NOx).    Lightning is a major source of NOx to 
 the atmosphere.\n\nIn this presentation I explore the relationships between
  ice particle morphology\, lightning\, and NOx\, based upon data collected 
 in the Deep Convective Clouds and Chemistry experiment in 2012.   The goal 
 of this work is to relate the chemical properties of thunderstorm-processed
  air to the ice found in the storm and to the physical processes that deter
 mine the ice particle morphology\, such as aggregation\, depositional growt
 h\, electrification\, etc.   I also describe the airborne laboratories used
  for these studies and how university faculty and students can use them for
  their own research interests.      \n\nSeminar by:\n\nJeffrey L. Stith\, P
