Northern versus Southern Hemispheresphenophysiognomyunique plant typesvegetation analogszonal biomesBiogeographic comparisons help to identify similarities, differences, larger contexts, and useful hypotheses. Between the (extra-tropical) Northern and Southern Hemispheres taxonomy differs almost completely, but ...
Atmospheric circulation changes during boreal winter of the second half of the twentieth century exhibit a trend toward the positive polarity of both the Northern Hemisphere annular mode (NAM) and the Southern Hemisphere annular mode (SAM). This has occurred in concert with other trends in the cli...
Drought frequency and severity are projected to increase in the future, but the changes are expected to be unevenly distributed across the globe. Based on multi-model simulations under three different future emissions and shared socioeconomic pathways, w

Long-term demise of sub-Antarctic glaciers modulated by the Southern Hemisphere Westerlies ArticleOpen access16 April 2021 Introduction During glacial terminations, retreating ice sheets release large meltwater fluxes into the ocean. This leads to rising sea level and can initiate strong climate feedbacks...
Stationary waves are planetary-scale longitudinal variations in the time-averaged atmospheric circulation. Here, we consider the projected response of Northern Hemisphere stationary waves to climate change in winter and summer. We discuss how the response varies across different metrics, identify robust re...
In this study, using ERA5 reanalysis data, we examine the physical chain of events responsible for the interannual variation of the Hadley cell edge (HCE) latitude in the Northern Hemisphere. This variation is mainly caused by changing eddy activity and wave breaking from both stationary and ...
air outbreaks over multiple regions in the Northern Hemisphere, which may help with mitigating their impact. Introduction Fig. 1: Three widely reported CAOs in recent years and the risk of CAOs. Results Relationship between the polar vortex and severe CAOs...
In August 2022, unprecedented and long-lasting extreme heatwaves attacked the Northern Hemisphere, with simultaneous record-breaking surface air temperature (SAT) in Eastern Europe (EE), Southern China (SC), and Western North America (WNA). However, the underlying physical mechanisms of these concur...
Moving on to the longitude versus height potential vorticity and meridional winds, the trends here reveal some compelling insights. Meridional winds are aligned with the vorticity patterns within these disturbances. The absolute or relative vorticity is most prominent in the lower troposphere (Fig. 2c...
