Impact of foreshock transients on the Earth’s magnetosphere and ionosphere

Foreshock transients play a role in the solar wind-magnetosphere coupling. The dynamic pressure perturbations associated foreshock transients can locally distort the magnetopause, which drives disturbances within the magnetosphere and ionosphere. In the first part of my talk, I will give a brief introduction of the geospace environment and the impact from the solar wind. In the second part, I will talk about the foreshock and foreshock transients and give an overview on what we have learned in the past decade. In the third part, I will present our recent global hybrid simulation work on the evolution of foreshock transients and their impact on the magnetosphere and ionosphere.

Bio: Got bachelor degree in Atmospheric Sciences at National Taiwan University in 1991 
Got master degree in Physics at National Taiwan University in 1993 
Got PhD in Space Physics at UCLA in 2002 (in Dept of Atmospheric and Oceanic Sciences)
Stayed at UCLA since 2002, now full researcher
Research interest in the Earth’s magnetotail and plasma sheet, solar wind-magnetosphere coupling, and magnetosphere-ionosphere coupling, using both observation and simulations.
