摘要
利用北半球26个高纬度到低纬度电离层探空站所有可用的N m F2观测资料,分析了与地磁活动无关的电离层F2层扰动(Q扰动)。正Q扰动和负Q扰动均出现,其振幅与中等的f2层风暴效应相当。Q扰动的发生与太阳活动、季节和当地时间有系统的关系。正、负Q扰动的空间变化规律不同,正、负Q扰动的幅值随纬度增大而增大,而正、负Q扰动的幅值几乎与纬度无关。这两种扰动振幅的纵向变化看起来像一个行星波,在美国扇区偏差最小,在欧洲扇区偏差最大。在这种波的前部可以出现nmf2的大的纵向梯度。
Correction to “Observations of neutral winds and electric fields using backscatter from field-aligned irregularities”
Ionospheric F2-layer disturbances not related to geomagnetic activity (Q disturbances) were analyzed using all available N m F2 observations over 26 Northern Hemisphere high-to-lower latitude ionosonde stations. Both positive and negative Q disturbances were revealed, their amplitude being comparable to moderate F2-layer storm effects. The occurrence of Q disturbances exhibits a systematic dependence on solar activity, season, and local time. Spatial variation pattern is different for positive and negative Q disturbances with the amplitude of the former increasing with latitude while the amplitude of the latter being practically latitudinal-independent. Longitudinal variations of the amplitude for both types of disturbances look like a planetary wave with minimal deviations in the American sector and maximal deviations in the European sector. Large longitudinal gradients in N m F2 can appear on the front of such waves.
