Research Highlights

Qian Wu, Dong Lin, Wenbing Wang, Liying Qian, Geonhwa Jee, Changsup Lee, and Jeong-han Kim use balloon instrument in the northern hemisphere and ground based instrument in the southern hemisphere to study the conjugacy of the thermospheric winds of high latitudes.

André SW Teruya, Víctor C Mayta, Breno Raphaldini, Pedro L Silva Dias, and Camila R Sapucci use a normal-mode decomposition method to analyze South American intraseasonal variability (ISV). This demonstrated that a realistic circulation can be reproduced, giving a powerful tool for diagnosing and studying the dynamics of waves and the interactions between them in terms of their ability to provide causal accounts of the features seen in observations.

Han-Li Liu and Astrid Maute use a whole atmosphere general circulation model, WACCM-X, to reproduce the pattern of the vertical ion motion similar to that observed during low activity solar cycle periods. 

H.-L. Liu, P. H. Lauritzen, F. Vitt, and S. Goldhaber have developed a high-resolution whole atmosphere model (WACCM-X), which extends from the Earth surface to the upper thermosphere, that can partially resolve the small scale wave quantification. 

Philip Judge, Lucia Kleint, and Christoph Kuckein use measurements of photospheric and chromospheric magnetic fields from the GREGOR GRIS instrument, to refute the idea that magnetic reconnection of network magnetic fields with granular fields drives coronal heating.

Sarah Gibson, et al. present a comprehensive study for a filament-embedding active region as determined from observations from multiple facilities including the Chinese Hα Solar Explorer (CHASE). The spectral resolution of CHASE is as high as 0.024 ̊A pixel−1, which enables an accurate determination of the chromospheric Doppler velocity that is especially crucial for probing the relative stable structure investigated here. 

Anett Elek, Marianna B. Korsós, Mausumi Dikpati, Norbert G. Gyenge, Bernadett Belucz, and Robertus Erdélyi, using data from the Debrecen Solar Faculae Database, investigated the spatiotemporal distribution of photospheric faculae between 2010 May 1 and 2014 December 31. Photospheric faculae are markers of the solar magnetic field, appearing as bright regions along the edges of granules on the Sun's surface.

Kun Wu, Liying Qian, Wenbin Wang, Xuguang Cai, Joseph M. Mclnerney investigate in detail the occurrence and evolution of ionospheric equatorial plasma bubbles (EPBs) during a moderate storm on September 17th, 2021, using Global-scale Observation of the Limb and Disk (GOLD) observations and Whole Atmosphere Community Climate Model-eXtended (WACCM-X) simulations.

Matthias Rempel, Georgios Chintzoglou, Mark C. M. Cheung, Yuhong Fan, and Lucia Kleint present a new simulation setup using the MURaM radiative Magnetohydrodynamic (MHD) code that allows to study the formation of collisional polarity inversion lines (cPILs) in the photosphere and the coronal response including flares. In this scheme we start with a bipolar sunspot configuration and set the spots on collision course by imposing the appropriate velocity field at the footpoints in the subphotospheric boundary.
