Abstract

Ionospheric disturbances during meteorological storms in the Kaliningrad region with a wind amplification of 8 points or higher on the Beaufort scale for the period 2010–2018 are analyzed. Ionospheric observations made under conditions of low geomagnetic activity are considered. Analysis shows that all of the selected events were accompanied by disturbances of the total electron content (TEC) and/or the electron concentration at the maximum of the F2 layer ionosphere (foF2) a few hours after reaching the maximum in the surface wind speed. Moreover, in four of six cases, the disturbances exceed the standard deviation of the values from the average median values by two times. Negative disturbances of TEC and foF2 (decrease in values) were observed in four cases, and positive disturbances (an increase in TEC and foF2) were observed in two cases. Disturbances were observed for at least 3 h, mainly in the daytime. The relative disturbances of the TEC due to meteorological storms exceed the corresponding foF2 disturbances.

气象风暴期间的电离层扰动

摘要

分析了加里宁格勒地区气象风暴期间的电离层扰动，其风放大倍数为2010-2018年期间的Beaufort等级为8点或更高。考虑在低地磁活动条件下进行的电离层观测。分析表明，所有选择的事件都伴随着总电子含量（TEC）和/或F 2层电离层最大值（foF 2）的电子浓度扰动，在达到表面风的最大值后几小时速度。此外，在六种情况中的四种中，干扰超过值与平均中值的标准偏差两倍。TEC和foF的负面干扰在4例中观察到2（值降低），在2例中观察到正干扰（TEC和foF 2升高）。观察到至少3小时的干扰，主要在白天。由于气象风暴，TEC的相对干扰超过了相应的foF 2干扰。
