摘要

摘要: 文中利用国际GNSS服务（IGS)提供的全球电离层地图（GIM)格网电离层资料,借助滑动四分位距法,研究了2019年台风“利奇马”期间电离层电子浓度总含量(TEC)的异常变化情况. 对台风“利奇马”期间电离层 TEC 时序变化及区域空间变化进行分析,发现在台风发生前第5天,电离层 TEC 出现了正异常变化;台风登陆后第二天,台风影响区域上空电离层 TEC 异常由正异常变化为负异常再变化为正异常,正异常最大值达8 TECU,负异常最大值达6 TECU,且最大异常点并不在风眼处,而是在风眼的西南侧,此异常可能与台风登陆期间台风风速及风向变化有关.

Abstract: In this paper we use the global GIM grid ionosphere data provided by IGS to investigate the ionospheric TEC disturbances induced by typhoon lekima in 2019. By means of the sliding interquartile range method, the temporal and regional spatial changes of the ionospheric TEC during typhoon Lekima were analyzed. It was found that the ionospheric TEC showed positive abnormal changes on the fifth day before the typhoon. On the second day after typhoon landing, the ionospheric TEC anomaly over the typhoon affected area changes from positive anomaly to negative anomaly and then changes to positive anomaly. The maximum value of positive anomaly reaches 8 TECU, and the maximum value of negative anomaly reaches 6 TECU. The maximum abnormal point does not coincide with the eye of the wind, but appears in the southwest region of the centre. This analysis suggests that this ionospheric TEC disturbances may be related to the change of wind speed and direction during the landing of typhoon
