Chinese scientists find evidence of lunar tide effects in Earth's plasmasphere

BEIJING, 1st February, 2023 (WAM) – A group of Chinese and international scientists have made a groundbreaking discovery in the Earth's plasmasphere, a region of the magnetosphere filled with cold plasma. For the first time, they have found evidence of a lunar tide-induced signal in the plasmasphere, Xinhua news agency reported.

The study was conducted by scientists from Shandong University, the Institute of Geology and Geophysics of the Chinese Academy of Sciences, and other institutes and was published in Nature Physics. The team analyzed data from over 10 satellites over the past 40 years and found that the lunar tide-induced signal in the plasmasphere has distinct diurnal and monthly periodicities, different from previously observed lunar tide effects in other regions.

These findings provide important information for future studies in other planetary systems and broaden our understanding of Earth-Moon interactions.
