I am an atmospheric dynamist with a broad interest in geophysical fluid dynamics and climate sciences. As a postdoc at Dr. Zhiming Kuang‘s group at Harvard, my research focuses on the large-scale jetstream dynamics, and more specifically on the phenomenon of atmospheric blocking and high-impact extreme weather events.

Sub-seasonal to seasonal variability poses a forecast gap between medium-range and seasonal timescales. High-impact extreme events such as heatwaves, cold spells, and heavy precipitation episodes often occur on this key timescale, and are challenging to predict.

I have recently obtained a Ph.D. in Geophysical Sciences from The University of Chicago. Under the direction of Dr. Noboru Nakamura, my dissertation research is focused on the theoretical aspects of geophysical fluid dynamics, in particular the fundamental dynamics of a 20-30 day periodic behavior in the storm tracks – a newly identified climatic driver and early warning of extremes.

  • Please check out our new paper on GRL (link) that, in collaboration with Dr. Jian Lu and Dr. Zhiming Kuangwe discover a robust increase of the underlying large-scale tone regulating intense precipitation events in response to global warming. This finding serves as a stimulus for future theoretical studies to unveil the role of changing diabatic heating — an exciting yet overlooked key physical process for understanding extreme weather events.

 

  • A review article titled “The influence of Arctic Amplification on mid-latitude summer circulation (link)”, led by Dr. Dim Coumou and I also contributed, has been published on Nature Communication. The accelerated global warming signal in the Arctic might have profound impacts on Jetstreams and storm tracks. We identify key knowledge gaps, physical mechanisms, dynamical feedbacks, and make suggestions for future research.
