Transport into the polar stratosphere from the Asian monsoon region by X. Yan, P. Konopka, F. Ploeger, F. Ploeger, A. Podglajen

“…We use SF<span class="inline-formula">₆</span> observations and the Lagrangian chemistry transport model Chemical Lagrangian Model of the Stratosphere (CLaMS), driven by the ERA5 reanalysis data for the period 2010–2014, to assess the impact of the Asian monsoon (AM) region (15–45° N, 30–120° E) as a significant source of pollutants for the stratosphere, in particular in polar regions. We examine the contribution of transport from the AM region to the Northern Hemisphere polar region (NP) (60–90° N) and to the Southern Hemisphere polar region (SP) (60–90° S). …”

Reply to Comment by A. G. Davies on “Io Hot Spot Distribution Detected by Juno/JIRAM” by F. Zambon, A. Mura, F. Tosi

“…They identified 242 hot spots, including 23 not previously reported in other catalogs, observing a higher hot spot number density in the northern polar region. Davies (2024) disputes location and counting of part of these hot spots, attributing the differences between the Zambon et al. (2023, https://doi.org/10.1029/2022gl100597) results and those obtained by Davies et al. (2024, https://doi.org/10.1038/s41550‐023‐02123‐5) to a misregistration of the JIRAM images. …”

Nighttime Geomagnetic Response to Jumps of Solar Wind Dynamic Pressure: A Possible Cause of Québec Blackout in March 1989 by T. Zhang, Y. Ebihara, T. Tanaka

“…We suggest that the blackout in Québec could be caused by the MI‐associated Hall current passing over the Hydro‐Québec power system on the nightside. The nighttime polar region is shown to be sensitive to hazardous GICs for large‐amplitude jumps in the solar wind dynamic pressure.…”
