161. 【BCAS】Interplanetary Shocks Trigger Magnetic Field Disturbances in Geospace
 
Keywords:     Published time:2015-08-17 17:16
162. First study on the X-ray imaging of Kelvin-Helmholtz waves at the magnetopause
    The solar wind charge exchange (SWCX) process occurs when a high charge state solar wind ion (e.g., O7+) encounters a neutral atom or molecule (e.g., H) and picks up an electron in an excited state. The ion then emits a photon when it decays to a lower energy state and thus may lead to the sate

163. NSSC Scientists Reveal the Chain Response of the Magnetospheric and Ground Magnetic Field to Interplanetary Shocks
    The interplanetary (IP) shock is a kind of strong discontinuity, which can bring about significant variations of solar wind parameters during a short time interval, introducing perturbations into the geospace environment. Therefore, intensive research on the geoeffectiveness of the IP shock is

164. Long-term Variation of the Trapped Protons in the SAA Revealed by NSSC Scientists
    Since Earth’s geomagnetic field is not a perfect dipole, the inner Van Allen radiation belt gets closer to the Earth over the South Atlantic Ocean dipping down to an altitude of 200km. This peculiar area is called the South Atlantic Anomaly (SAA). It will leads to an increased flux of energeti

165. AMAS Channel Specifications and T/V Calibration Results on FY-3C Satellite Revealed
    When the Microwave Humidity Sounder (MWHS) on board FY-3 (A/B) was designed in the Key Laboratory of Microwave and Remote Sensing at the National Space Science Center (NSSC), the research group perhaps hadn’t envisioned that before long, it will be optimized and replaced by its better version,

168. 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

169. Two Classes of High-speed Flow Found Exist in the Magnetotail Causing Different Effect of Geospace environment
 Recently, based on observations from NASA’s THEMIS mission (The Time History of Events and Macroscale Interactions during Substorms), two researchers from the State Key Laboratory of Space Weather, the National Space Science Center (NSSC), Dr. LI Hui and Prof. WANG Chi, jointly with Prof. FU Suiyan

170. 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
