磁暴期间长城站电离层扰动及中性风分析

本文分析了磁暴期间南极长城站的电离层扰动性质性。采用一个半经验模式利用垂测数据计算了磁暴效应引起的有效应引起的有效热层子午向中性风。发现暴时有效中性风对电离层正相扰动的形式起主要作用，并对长城站电离层正负相扰动的可能机制进行了分析。

Investigations on Pelationship between Ionospheric Disturbance and Neutral Winds during Geomagnetic Storms at the Great Wall Station, Antarctic

In this paper, ionospheric disturbances during geomagnetic storms at the Great Wall station in Antarctic are studied. Baed on the ionosonde data, we used an empirical method to derive the neutral meridional wind during tile storm. A good correlation between the positive ionospheric disturbances and the vacation of neutral winds has been found. It indicates that neutral winds make a significant contribution to the peitive ionospheric disturbance. The possible mechanisms of ionospheric disturbances are also discussed.
