Hi, I'm Kai

Advancded Study Program (ASP) Postdoctoral Fellow II,

Climate & Global Dynamics (CGD) Lab

National Center for Atmospheric Reserach

I like working with numerical models and observational data of our earth system. I enjoy exploring the physical dynamics behind the climate and weather systems and applying them in weather/climate models to improve their prediction skills.

My research interests include but are not limited to

equatorial convectively coupled waves
coupling between stratosphere and troposphere
subseasonal to seasonal (S2S) weather prediction
large-scale atmospheric circulations.

I'm joining the National Center of Atmospheric Research (NCAR) as a Advanced Study Program (ASP) Postdoc Fellow in this June.

My current research includes: the diversity of Madden-Julian Oscillation (MJO) modulated by interannual variations[1], the influences of the Quasi-Biennial Oscillation (QBO) on MJO in weather prediction systems[webinar], and the MJO simulation in climate models[3].

I'm using the CESM2 subseasonal prediction system to capture the QBO-MJO connection which has been missing in all current generation climate models. For the first time, we found a nudging strategy that could capture such connection in a global model, providing a new perspective to understand the physics behind and to improve the S2S predictions. If you are also interested in these research topics, please do not hesitate to reach out to me!

Tools I use for my research

Models: CESM2 subseasonal prediction system, Beijing Climate Center Climate Sytem Model version 1.2 (BCC_CSM1.2).

Programming language: Python, Matlab, NCL, Fortran, R, LaTex, bash scripting.
