Collaboration Summary

I collaborated with Prof. Ji Nie at Peking University on two undergraduate research projects between 2019 and 2021:

October 2019 — May 2020: Walker / Hadley circulation response under global warming, using CMIP6 multi-model picontrol / abrupt2x / abrupt4x data to study circulation intensity changes and contribution decomposition across different CO₂ levels.
November 2020 — October 2021: Walker circulation dependence on ocean basin width, using the CAM3 aqua-planet framework with 10 cases × 30-year runs, during which a Linear Superposition analytical framework was developed.

The collaboration produced a 3663-word draft paper preserved in my personal archive. Prof. Nie provided systematic methodological training during my PKU undergraduate research years (paper reading, group seminar presentations, numerical experiment design). He is one of the PKU undergraduate research advisors explicitly acknowledged in my senior thesis.

Research Direction

Prof. Nie’s research focuses on tropical atmospheric dynamics and the response of large-scale circulation to climate change. His work spans intensity and structural changes in the Walker / Hadley circulation, physical mechanisms relevant to climate sensitivity, and diagnostic analysis based on multi-model and idealized numerical experiments (CMIP, CAM aqua-planet, and related frameworks).
