Research

Simulating the Initiation and Liftoff Phases of CMEs

Personal Introduction

I'm not productive for a long time, so the anticipation is that my home page will not be updated for the next few months, at least.

Specializations and Research Interests

  • Coronal Mass Ejection (CME) Earth Arrival Time Prediction

      CMEs are massive eruptions of solar plasma that propagate in the interplanetary space. They can cause adverse geomagnetic disturbances if are Earth-directed. So we would like to accurately predict their arrival time at the Earth, with a simple and fast kinematics method (rather than time-consuming yet not-so-accurate simulations). We make a statistical study of 21 Earth-directed CMEs by reconstructing their initial speeds with the Graduated Cylindrical Shell model based on multi-perspective images and formulating their interplanetary motions with the drag force model. We show significantly imporved prediction results with an error of only 6.8 hours. Thus, it provides a neat method of space weather forecast of 1–5 days following the occurrence of CMEs.

Honors, Awards and Accomplishments

  • NASA Earth and Space Science Fellowship
  • Youxiu Biyesheng & Youxiu Biyelunwen (summa cum laude?)
  • CUPT Second Prize, UPC Silver & MCM Honorable (I guess no one knows these...)
