Abstract

Based on the data of ionosondes at four different mid-latitude stations of Manzhouli (49.6°N, 117.5°E), Beijing (40.1°N, 116.2°E), Suzhou (31.3°N, 120.4°E) and Guangzhou (23.2°N, 113.4°E) in China region during maximum (2013–2015) and minimum (2019–2021) solar activity years, the effects of solar activity on the Es layer traces, velocity and lifetime of descending Es layers are analyzed. The results show that the Es layer traces, height distribution and incidence of Es layers are negatively correlated with solar activities, while solar activities have little influence on the descent velocity and lifetime of descending Es layers. The simulation and spectral analysis results show that the descent velocity and lifetime of Es layers are mainly influenced by atmospheric tidal waves.

Es层与太阳活动关系的分析与模拟

利用中国地区满洲里（49.6°N, 117.5°E）、北京（40.1°N, 116.2°E）、苏州（31.3°N, 120.4°E）和广州（23.2°N, 113.4°E） 4个不同中纬度站点在太阳活动最大年（2013-2015年）和最小年（2019-2021年）的电离层探测资料，分析了太阳活动对Es层下降轨迹、速度和寿命的影响。结果表明，Es层迹线、Es层高度分布和Es层入射与太阳活动呈负相关，而太阳活动对Es层下降速度和下降寿命影响不大。模拟和光谱分析结果表明，Es层的下降速度和寿命主要受大气潮汐波的影响。

期刊介绍： The COSPAR publication Advances in Space Research (ASR) is an open journal covering all areas of space research including: space studies of the Earth''s surface, meteorology, climate, the Earth-Moon system, planets and small bodies of the solar system, upper atmospheres, ionospheres and magnetospheres of the Earth and planets including reference atmospheres, space plasmas in the solar system, astrophysics from space, materials sciences in space, fundamental physics in space, space debris, space weather, Earth observations of space phenomena, etc. NB: Please note that manuscripts related to life sciences as related to space are no more accepted for submission to Advances in Space Research. Such manuscripts should now be submitted to the new COSPAR Journal Life Sciences in Space Research (LSSR). All submissions are reviewed by two scientists in the field. COSPAR is an interdisciplinary scientific organization concerned with the progress of space research on an international scale. Operating under the rules of ICSU, COSPAR ignores political considerations and considers all questions solely from the scientific viewpoint.
