  talk by\n\nJiwen Fan\n	Senior Scientist\n	Pacific Northwest National Labora
 tory \n\nDeep convective clouds (DCCs) play a crucial role in the general 
 circulation\, energy\, and hydrological cycle of our climate system. How a
 erosol particles may influence DCCs could be very complicated due to convo
 luted microphysical and dynamical processes and feedback associated with d
 eep convection. The large uncertainty has been obstructing us to achieve b
 etter weather and climate predictions. In this talk\, I will present our r
 ecent understandings of how aerosols could change convection\, extreme pre
 cipitation\, and cloud anvil in upper atmosphere by serving as cloud conde
 nsation nuclei and ice nuclei\, which are gained from process-level studie
 s with both advanced observations and high-resolution model simulations. I
  will also demonstrate how aerosol-radiation interaction can escalate a re
 gular precipitation event to a catastrophic flooding event. Some significa
 nt challenges and future directions will be discussed.\n\nDr. Jiwen Fan is
  a Senior Earth Scientist at Pacific Northwest National Laboratory (PNNL).
  She received her Ph.D. degree in 2007 from Texas A&M University. Her expe
 rtise encompasses atmospheric chemistry and aerosols\, clouds\, convection
 \, and extreme storms. Her work contributes to improving physical understa
 nding of the complex aerosol interactions with cloud microphysics and dyna
 mics. Her current work includes (1) physical factors impacting severe stor
 ms\, particularly under the context of urbanization\, wildfires\, and clim
 ate warming.\, (2) understanding meso-scale convective systems (MCSs) and 
 improving global model capability in simulating MCSs\, (3)development of c
 loud microphysics parameterizations for climate models\, and (4) impacts o
 f marine aerosol and dust on orographic mixed-phase clouds.\n\nJiwen has p
 ublished 92 peer-reviewed journal papers\, with a H-index 34 in ISI Web of
  Science. She won several prestigious research awards including 2015 AGU A
 SCENT award for exceptional mid-career scientists and 2018 AMS STEM Outsta
 nding Service award. She was a recipient of U.S. Department of Energy (DOE
 ) Early Career Research award.\n\nMonday Nov 18/ 3:30 PM/ Burnside Hall/ R
