163. First Statistical Study on K-H Wave Properties at Earth’s Magnetopause made by NSSC Scientists
 Have you ever seen wind blowing over water when the instability manifests in waves on the water surface? Well, it’s similar for the Kelvin-Helmholtz (K-H) waves. To be more specific, “Kelvin-Helmholtz Instability” can be excited at the interface if there is sufficient velocity shear between the t

165. New CME/Shock Arrival Time Prediction Model Proposed by NSSC Scientists
 Solar transients, such as coronal mass ejections (CMEs) and their related interplanetary (IP) shock waves, have severe space weather effects. Therefore, predicting their evolutions in the heliosphere and arrival times at Earth is an important component of space weather predictions. Recently, a new g

166. NSSC Scientists Reveal the Entropy Generation Mechanism across a Collisionless Shock
 Collisionless shocks are of great interest in space physics, plasma physics, and astrophysics. In the shock transition, the bulk energy of plasma is converted into thermal energy in the absence of particle collisions. The shock is also thought to be an important source of high-energy particles (e.g.
