AN ALL-SKY SEARCH FOR THREE FLAVORS OF NEUTRINOS FROM GAMMA-RAY BURSTS WITH THE ICECUBE NEUTRINO OBSERVATORY by Arguelles Delgado, Carlos A, Collin, G. H., Conrad, Janet Marie, Jones, Benjamin James Poyner

“…The results of this search in combination with those of IceCube's four years of searches for track-like Cherenkov light patterns from muon neutrinos correlated with Northern-Hemisphere GRBs produce limits that tightly constrain current models of neutrino and ultra high energy cosmic ray production in GRB fireballs. …”

Observed changes in Brewer–Dobson circulation for 1980–2018 by Solomon, Susan

“…This overall acceleration was driven by both Northern Hemisphere (40%) and SH (60%) cells. Significant SH radiative warming is also identified in September for 2000–2018 after excluding the year 2002 when a very rare SH stratospheric sudden warming occurred, supporting the view that healing of the Antarctic ozone layer has now begun to occur during the month of September. ©2019…”

K2-291b: A Rocky Super-Earth in a 2.2 day Orbit

“…From our 75 radial velocity measurements using High Resolution Echelle Spectrometer on Keck I and High Accuracy Radial velocity Planet Searcher in the northern hemisphere on Telescopio Nazionale Galileo, we constrained the mass of K2-291 b to M p = 6.49 ±1.16 M ⊕ . …”

Stratospheric Ozone in the Last Glacial Maximum by Wang, Mingcheng, Fu, Qiang, Solomon, Susan, White, Rachel H, Alexander, Becky

“…Surface ultraviolet radiation in the LGM versus PI is increased over the Northern Hemisphere middle and high latitudes, especially over the ice caps, and over the Southern Hemisphere near 60°S.…”

A Search for Neutrino Emission from Fast Radio Bursts with Six Years of IceCube Data by IceCube Collaboration, Arguelles Delgado, Carlos A, Axani, Spencer Nicholas, Collin, G. H., Conrad, Janet Marie, Moulai, Marjon H.

“…We set the most stringent limit obtained to date on neutrino fluence from FRBs with an E -2 energy spectrum assumed, which is 0.0021 GeV cm-2 per burst for emission timescales up to ∼102 s from the northern hemisphere stacking search.…”

Ozone affects plant, insect, and soil microbial communities : a threat to terrestrial ecosystems and biodiversity by Agathokleous, Evgenios, Feng, Zhaozhong, Oksanen, Elina, Sicard, Pierre, Wang, Qi, Saitanis, Costas J., Araminiene, Valda, Blande, James D., Hayes, Felicity, Calatayud, Vicent, Domingos, Marisa, Veresoglou, Stavros D., Peñuelas, Josep, Wardle, David A., De Marco, Alessandra, Li, Zhengzhen, Harmens, Harry, Yuan, Xiangyang, Vitale, Marcello, Paoletti, Elena

“…We suggest that Atlantic islands in the Northern Hemisphere, the Mediterranean Basin, equatorial Africa, Ethiopia, the Indian coastline, the Himalayan region, southern Asia, and Japan have high endemic richness at high ozone risk by 2100.…”

The role of Holocene relative sea-level change in preserving records of subduction zone earthquakes by Dura, Tina, Engelhart, Simon E., Vacchi, Matteo, Horton, Benjamin Peter, Kopp, Robert E., Peltier, W. Richard, Bradley, Sarah

“…In near-field regions that were located beneath northern hemisphere ice sheets (e.g., western Vancouver Island), RSL fall from a mid-Holocene highstand has limited prehistoric earthquake records to the last 1 ka. …”

Validation of boreal summer tropical–extratropical causal links in seasonal forecasts by Di Capua, G, Coumou, D, van den Jurk, B, Weisheimer, A, Turner, A, Donner, R

“…We calculate causal maps based on the Peter and Clark momentary conditional independence (PCMCI) causal discovery algorithm, which identifies causal links in a 2D field, to show the causal effect of each of these patterns on circulation and convection in the Northern Hemisphere. The spatial patterns and signs of the causal links in SEAS5 closely resemble those seen in ERA5, independent of the initialisation date of SEAS5. …”

Formal methods for evolutionary inference using ancient DNA by Loog, L

“…The second approach combines spatially and temporally explicit simulations with ancient mitochondrial genome data, spanning the Northern hemisphere and the last 50 thousand years to reconstruct large- scale population dynamics in Grey wolves over this time period. …”

Upper-ocean singular vectors of the North Atlantic climate with implications for linear predictability and variability by Zanna, L, Heimbach, P, Moore, A, Tziperman, E

“…An initial density perturbation of merely 0.02 kg m -3 is found to lead to a 1.7 Sv MOC anomaly after 18.5 years. In addition, Northern Hemisphere upper-ocean temperature perturbations can be amplified by a factor of 2 after 13 years. …”

Sensitivity of stratospheric dynamics and chemistry to QBO nudging width in the chemistry-climate model WACCM by Hansen, F, Matthes, K, Gray, L

“…The sensitivity to the nudging width is strongest in Northern Hemisphere (NH) winter where the Holton-Tan effect in the polar stratosphere, i.e., stronger zonal mean winds during QBO west phases, is enhanced for the wider compared to the narrower nudging case. …”
