Postdoctoral researcher

Time: 2019/05 – now

Place: Earth and Planetary Science Department, The Universiy of Tokyo

Research Group: Atmospheric Environmental Science/Atmospheric Chemistry

Work:

• Arctic mixed-phase clouds are an important piece in regulating the Arctic climate. There are still much unknown about why mixed-phase clouds frequently and persistently appear in the Arctic region because it is known that ice-liquid mixed-phase clouds are unstable.
• In light of the reason above, I work on the implementation of a microphysics scheme (AMPS, developed by Hashino and Tripoli, 2007, 2008, 2011) that can predict the evolvement of the geometry of ice particles and mass composition into an LES model (SCALE, https://scale.riken.jp/ja/) and running simulations of Arctic mixed-phase stratiform clouds. This model is now called SCALE-AMPS.
• I am currently working on the relationship between ice geometry and the lifetime of mixed-phase clouds. This is to understand the role of ice microphysics in the maintenance of Arctic mixed-phase clouds using the SCALE-AMPS model.
