Role of multi-decadal variability of the winter North Atlantic Oscillation on Northern Hemisphere climate by Andrew P Schurer, Gabriele C Hegerl, Hugues Goosse, Massimo A Bollasina, Matthew H England, Doug M Smith, Simon F B Tett

“…Concentrating on the 28 year periods of strongest observed NAO trends, we show that NAO variability leads to large multi-decadal trends in temperature and precipitation over Northern Hemisphere land as well as in sea-ice concentration. …”

A cleaner snow future mitigates Northern Hemisphere snowpack loss from warming by Dalei Hao, Gautam Bisht, Hailong Wang, Donghui Xu, Huilin Huang, Yun Qian, L. Ruby Leung

“…Here, using Earth System Model simulations, we project significantly reduced black carbon deposition by 2081-2100, which reduces the December-May average LAP-induced radiative forcing in snow over the Northern Hemisphere from 1.3 Wm−2 during 1995-2014 to 0.65 (SSP126) and 0.49 (SSP585) Wm−2. …”

Weakening of decadal variation of Northern Hemisphere land monsoon rainfall under global warming by Yeyan Jiang, Juan Li, Bin Wang, Youngmin Yang, Zhiwei Zhu

“…Abstract Over the past century, Northern Hemisphere (NH) land monsoon rainfall (NHLMR) experienced significant decadal to multidecadal variations, mainly driven by an east–west sea surface temperature (SST) contrast over the Pacific (EWPC) and an interhemispheric North Atlantic–South Indian Ocean SST dipole (NAID). …”

Climate Controls on the Spatial Variability of Vegetation Greenup Rate across Ecosystems in Northern Hemisphere by Zhoutao Zheng

“…In this study, the rate of vegetation greenup (Vgreenup) across the Northern Hemisphere was examined for different plant functional types (PFTs) by using eddy covariance flux data from 40 sites (417 site-years). …”

Climate warming-induced phenology changes dominate vegetation productivity in Northern Hemisphere ecosystems by Chaoya Dang, Zhenfeng Shao, Xiao Huang, Qingwei Zhuang, Gui Cheng, Jiaxin Qian

“…Despite numerous existing efforts, however, their contradicting conclusions suggest that how vegetation productivity is impacted by these factors still remains unclear in the Northern Hemisphere ecosystems (≥25°N). This study used the optimal fingerprint (OFP) method and redundancy analysis (RDA) to attribute the importance of key drivers of vegetation productivity from 2001 to 2019 based on long-term remote sensing and FLUXNET observation data. …”

On the pattern of interannual polar vortex–ozone co-variability during northern hemispheric winter by F. Harzer, H. Garny, H. Garny, F. Ploeger, F. Ploeger, H. Bönisch, P. Hoor, T. Birner, T. Birner

“…In this work, we analyze interannual co-variations between the distribution of zonal-mean ozone and the strength of the polar vortex as a measure of dynamical activity during northern hemispheric winter. Specifically, we study co-variability between the seasonal means of the ozone field from modern reanalyses and polar-cap-averaged temperature at 100 hPa, which represents a robust and well-defined index for polar vortex strength. …”

Changes in Precipitation Extremes across Vietnam and Its Relationships with Teleconnection Patterns of the Northern Hemisphere by Quang Van Do, Hong Xuan Do, Nhu Cuong Do, An Le Ngo

“…To identify possible mechanisms driving changes in precipitation, we assessed the relationship between inter-annual variations in precipitation extremes and climate variability represented by the teleconnection patterns of the Northern Hemisphere. Using five climate indices, we found that teleconnections across the Indian and Pacific Oceans have implied large control over the characteristics of precipitation extremes across Vietnam, with up to 30% of Vietnam’s landmass exhibiting a significant relationship.…”
