Modeling Equatorial to Mid‐Latitudinal Global Night Time Ionospheric Plasma Irregularities Using Machine Learning by Ephrem Beshir Seba, Giovanni Lapenta

“…Our findings indicate that non‐equinox months exhibit the highest equatorial PI magnitude over the American‐African longitudinal sector, contrary to the expected higher Rayleigh‐Taylor instability growth rate during equinox months. …”

Understanding the effect of revolution and rotation of the earth on prayer times using accurate times by Abu Yazid Raisal, Arwin Juli Rakhmadi

“…Prayer times are calculated using the Accurate Times software during the equinox, summer solstice, and winter solstice in 2020. …”

The Relationship Between Upward Propagating Atmospheric Gravity Waves and Ionospheric Irregularities During Solar Minimum Periods by Ephrem B. Seba, Melessew Nigussie, Nigussie M. Giday, Mark B. Moldwin

“…Using these two independent set of measurements, we investigate the relationship between gravity waves and ionospheric irregularities on both equinox and solstice seasons for the years 2018–2019. …”

Investigating the Interhemispheric Asymmetry in Joule Heating During the 2013 St. Patrick's Day Geomagnetic Storm by A. R. Smith, D. S. Ozturk, P. Delamere, G. Lu, H. Kim

“…The timing, location, and sources of interhemispheric asymmetry during this geomagnetic storm are of key interest due to near equinox conditions. Hemispheric comparisons are made between parameters, including solar insolation, total electron content profiles, and Pedersen and Hall conductance profiles, obtained from GITM driven with empirical driven input, versus those driven with data‐assimilated patterns. …”

Effect of Ecotype and Latitude on Growth, Frost Hardiness, and Oxidative Stress of South to North Transplanted Scots Pine Seedlings by Erja Taulavuori, Kari Taulavuori, Ahti Niinimaa, Kari Laine

“…No delay in frost hardening due to higher latitude was observed during the autumnal equinox. No marked stress caused by transplantation to the north was either observed. …”

Daily Plasmaspheric TEC Variations From COSMIC GPS Observations Based on RBF Neural Network‐Kriging Method by Qiqi Shi, Shuanggen Jin, Linlin Li

“…Furthermore, daily PTEC variations show that the PTEC at low latitudes is evenly distributed during equinox periods. The South American‐Atlantic Ocean sector has a peak and trough in PTEC during the December and June solstices. …”

Magnetic Signatures of Ionospheric Disturbance Dynamo for CME and HSSWs Generated Storms by Waqar Younas, C. Amory‐Mazaudier, Majid Khan, M. Le Huy

“…The Ddyn duration is found to be maximum for the storms occurring during equinox season. Moreover, the HSSWs events are more likely to cause—because of the oscillatory IMF Bz—long lasting Ddyn as compared to CME generated counterpart. …”

Infestation patterns of a major wood boring pest, Psiloptera fastuosa (Buprestidae: Coleoptera) in Tasar, Terminalia arjuna (Myrtales: Combretaceae) plantation by Sumit Mandal, Avishek Dolai, Kartik Chandra Mandal, Amlan Das

“…The wood-boring Psiloptera fastuosa (Coleoptera: Buprestidae) causes severe threats to Tasar plantations during their mating season (September equinox to December solstice). After hatching, the coleopteran grubs puncture and penetrate the arjuna stem, mature into pupae inside, pass into adults, and exit through emergence holes, causing severe damage to younger plants. …”

Seasonal and Solar Cycle Dependency of Relationship Between Equatorial Plasma Bubbles and Rayleigh‐Taylor Instability Growth Rate by L. F. R. Vital, H. Takahashi, D. Barros, C. S. Carmo, A. J. Carrasco, C. M. Wrasse, C. A. O. B. Figueiredo

“…Additionally, the occurrence probability exhibited seasonal variations, with a gradual increase during the equinox months, minimal occurrence during the June solstice, and a sudden increase during the December solstice. …”

Challenges in Specifying and Predicting Space Weather by R. W. Schunk, L. Scherliess, V. Eccles, L. C. Gardner, J. J. Sojka, L. Zhu, X. Pi, A. J. Mannucci, A. Komjathy, C. Wang, G. Rosen

“…For this ensemble modeling study, we selected the quiet/storm period of 16 and 17 March 2013 (equinox, solar medium). Five data assimilation models and one physics‐based model were used to produce an ensemble mean output for Total Electron Content (TEC), ionospheric peak density (NmF2), and ionospheric peak height (hmF2) for latitudes less than 60° and all longitudes. …”

Occurrence of Ionospheric Equatorial Ionization Anomaly at 840 km Height Observed by the DMSP Satellites at Solar Maximum Dusk by Jiacheng Li, Yiding Chen, Libo Liu, Huijun Le, Ruilong Zhang, He Huang, Wenbo Li

“…The EIA can still be observed at DMSP heights, and the EOR can reach 30% at specific longitudes at dusk side in equinox seasons. The EOR behaves wave‐like longitude structure that depends on seasons. …”
