Geometric calibration of all-sky auroral imager based on gradient descent method and the star maps
The all-sky imager is an important ground-based auroral observation equipment. Accurate optical geometric correspondence between "object-image" is the foundation for obtaining the structural scale of auroras and achieving joint observations between the all-sky imager and satellites. This paper…

Venus's atmospheric superrotation
Venus, the planet closest to Earth, has a slowly retrograde rotation in the opposite direction to Earth's, and it has a dense atmosphere that exhibits rapid westward motion. At the cloud top, around 65–70 km in altitude, zonal wind speeds reach up to 100 m/s—about 50–60 times faster than the…

Recent advances in the interior structure of the gas giants
Jupiter and Saturn, as the gas giants of our solar system, account for over 90% of the total mass beyond the Sun and hold most of the system's angular momentum, playing a crucial role in the early history of the solar system. During their formation, these planets captured vast amounts of material…

Review on research status and development trends of solar radio spectrometers
Intense solar activity is a major driver of hazardous space weather. The associated processes, including strong electromagnetic radiation, plasma ejections, and high-energy particle acceleration, can significantly disturb the Sun-Earth environment within a short time and further trigger a series of…

Progress in research on atmospheric vortices of gas giant planets
The atmospheres of gas giant planets contain multi-scale vortex structures, which are not only key components of planetary weather systems but also important windows for understanding their internal dynamics and thermodynamic processes. This paper reviews recent advances in the study of atmospheric…

Review of the lunar charged particle environment
Charged particles constitute one of the essential physical elements within the lunar space environment. Their origins, compositions and energy spectra are remarkably complex, and their spatial distribution and temporal dynamics are intricately coupled with localized electromagnetic field…

The role of modified electron acoustic waves in the evolution of quasi-static parallel electric fields
The auroral arc is a common form of aurora. Its formation involves three processes: the transfer of disturbed energy from the source region to the acceleration region via Alfvén waves, the generation of acceleration structures within the acceleration region, and the acceleration of electrons to…

Dynamic process of the 2000 Yigong high-speed landslide
At Beijing time 19:58 on April 9, 2000, a large landslide occurred in Yigong area, Bomi County, Linzhi City, southeastern Qinghai-Xizang Plateau, caused extensive damage to about 8 km2 of forest, blocked the river and formed the Yigong lake. Seismic waves can remotely detect the occurrence process…

Advances in the spatiotemporal characteristics and mechanisms of earthquake static and dynamic triggering
The static and dynamic stress changes induced by earthquakes can further trigger seismic events on surrounding or even remote faults. This phenomenon, known as static and dynamic triggering of earthquakes, has significant implications for earthquake prediction and seismic hazard assessment…

Effects of large igneous provinces on the continental crustal structure, continental break-up and global climate changes
Large igneous provinces (LIPs) play an important role in crustal growth, metallogenesis of metal elements, global climate changes and life evolution. Despite extensive studies of near-surface geological records of LIPs, our knowledge about the middle-lower crustal intrusions of LIPs is very…

Source process of the 2021 MW6.6 outer rise earthquake off the west coast of northern Sumatra
The complexity of the seismicity pattern for the subduction zone along the oceanic plate triggered the outer rise events and revealed cyclic tectonic deformation conditions along the plate subduction zones. The outer rise earthquakes have been observed along the Sunda arc, following the estimated…

Theoretical analysis of interchange instability in Jupiter's inner magnetosphere
Interchange instability is widespread in both engineering applications and natural environments and is recognized as one of the primary mechanisms for radial mass transport within Jupiter's magnetodisk. In this study, the dispersion relation and the instability criteria of the interchange…

Differential motions of the Gozha Co Fault (Xizang) before and after the 2008 Yutian earthquake revealed by ENVISAT-1 ASAR
Shallow fault creep is a relatively rare phenomenon, often indicating a lower seismic risk (less strain accumulation). Previous studies have revealed shallow creep on the Gozha Co Fault in the western Qinghai-Xizang Plateau using Sentinel-1 and ALOS-2 data, but its formation mechanism remains…

Ground-based observations of ghost green emissions and analyses of their excitation background
Ghosts are a newly discovered category of transient luminescence events (TLEs) occurring in the middle and upper atmospheres above energetic thunderstorms. Due to the high requirements of optical shooting, the observation data that can be investigated are very scarce and are all obtained from the…

Research on temperature forecasting in near space based on CNN-LSTM algorithm
Near space refers to the complex transition region between the Earth's atmosphere and space, with its height between 20–100 km, including the stratosphere, the mesosphere and the lower thermosphere which are important components of the Earth's atmospheric system. The near space is affected not only…

Impact of eccentricity on regional aridity-humidity variations
Climatic aridity-humidity variations on orbital timescales are crucial for understanding the Earth's climate system response mechanisms. Investigating the relationship between orbital-scale eccentricity cycles and aridity-humidity changes helps clarify the mechanisms by which Earth's climate system…
