Mean age of stratospheric air derived from AirCore observations by A. Engel, H. Bönisch, H. Bönisch, M. Ullrich, R. Sitals, O. Membrive, F. Danis, C. Crevoisier

“…We have used the observations to extend our long-term data set of mean age observations at Northern Hemisphere midlatitudes. The time series now covers more than 40 years and shows a small, statistically non-significant positive trend of 0.15 ± 0.18 years decade⁻¹. …”

The Rotation and Galactic Kinematics of Mid M Dwarfs in the Solar Neighborhood by Newton, Elisabeth R., Irwin, Jonathan, Charbonneau, David, Dittmann, Jason A., West, Andrew A., Berta-Thompson, Zach

“…Using photometry from the MEarth Project, we measure rotation periods for 387 nearby, mid-to-late M dwarfs in the northern hemisphere, finding periods from 0.1 to 140 days. …”

Efficient early global relaxation of asteroid Vesta by Fu, Roger Rennan, Hager, Bradford H, Ermakov, Anton, Zuber, Maria

“…Based on crater retention ages, topography, and relation to known impact generated features, we identify a large region in the northern hemisphere that likely represents relic hydrostatic terrain from early Vesta. …”

Observations, inferences, and mechanisms of the Atlantic Meridional Overturning Circulation: A review by Buckley, Martha W., Marshall, John C

“…Northward ocean heat transport achieved by the AMOC is responsible for the relative warmth of the Northern Hemisphere compared to the Southern Hemisphere and is thought to play a role in setting the mean position of the Intertropical Convergence Zone north of the equator. …”

Uncertainty and variability in atmospheric formation of PFCAs from fluorotelomer precursors by Thackray, Colin P., Selin, Noelle E

“…Our calculations of theoretical maximum yields indicate that under typical Northern Hemisphere conditions, less than 10 % of emitted precursor may reach long-chain PFCA end products. …”

A flexible and robust neural network IASI-NH₃ by Whitburn, S., Van Damme, M., Clarisse, L., Bauduin, S., Hadji-Lazaro, J., Hurtmans, D., Zondlo, M. A., Clerbaux, C., Coheur, P.-F, Heald, Colette L.

“…A comparison with a GEOS-Chem modeled global distribution is also presented, showing a general good correspondence (within ±3 × 10¹⁵ molecules.cm⁻²) over most of the Northern Hemisphere. However, IASI finds mean columns about 1–1.5 × 10¹⁶ molecules.cm⁻² (∼50–60%) lower than GEOS-Chem for India and the North China plain.…”

Radiative Effects of Stratospheric Seasonal Cycles in the Tropical Upper Troposphere and Lower Stratosphere by Gilford, Daniel Michael, Solomon, Susan

“…Ozone's radiative effects are not spatially homogenous: for example, the Northern Hemisphere tropics have a seasonal cycle of radiative temperature adjustments with an amplitude 0.8 K larger than the Southern Hemisphere tropics. …”

Tropical cyclone activity enhanced by Sahara greening and reduced dust emissions during the African Humid Period by Pausata, Francesco S. R., Chiacchio, Marc, Diro, Gulilat T., Sushama, Laxmi, Stager, J. Curt, Donnelly, Jeffrey P., Emanuel, Kerry Andrew, Zhang, Qiong, S.M. Massachusetts Institute of Technology

“…Furthermore, whereas previous studies suggest lower TC activity despite stronger summer insolation and warmer sea surface temperature in the Northern Hemisphere, accounting for the Sahara greening and reduced dust concentrations leads instead to an increase of TC activity in both hemispheres, particularly over the Caribbean basin and East Coast of North America. …”

Localization of Deep Water Formation: Role of Atmospheric Moisture Transport and Geometrical Constraints on Ocean Circulation by Campin, Jean-Michel, Ferreira, David, Marshall, John C

“…Finally, it is argued that many gross features of the present climate are consequences of two topological asymmetries that have profound effects on ocean circulation: a meridional asymmetry (circumpolar flow in the Southern Hemisphere; blocked flow in the Northern Hemisphere) and a zonal asymmetry (a small basin and a large basin).…”

Tropical Cyclone Activity Downscaled from NOAA-CIRES Reanalysis, 1908-1958 by Emanuel, Kerry Andrew

“…When applied to the 1908-1958 reanalysis, the derived global frequency of tropical cyclones shows no significant trend over the period, while the frequency of events in the southern hemisphere shows a statistically significant decline and that of the northern hemisphere shows a marginally significant increase. …”
