Forbs in Viking lands: the effect of disturbing dominant graminoids on recruitment in tundra grasslands

Oikos, EarlyView.
Grasslands, by definition, are dominated by graminoids. Nevertheless, forbs also make up a substantial part of vascular plant diversity in grasslands and are important resources of mammalian herbivores. However, forb recruitment is constrained by successful dominant graminoids, limiting access to safe sites for germination.

Permafrost Mass Wasting in Ice‐Rich Landscapes: Recent Advances (2013 to 2024) on Mechanisms, Dynamics and Impacts

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Across circumpolar permafrost regions, climate change is destabilizing ice‐rich hillslopes, increasing the frequency and magnitude of thaw‐driven mass wasting. This paper reviews recent studies (2013–2024) on thaw‐driven mass wasting, focusing on the processes, morphology and trajectories of geomorphic change and their implications for ...

Cryostratigraphy of Rhythmic Segregated Ice in Colluvium and Implications for Permafrost Slope Stability

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The amount and stratigraphic setting of ground ice in permafrost slopes is a key control on the style and magnitude of permafrost mass wasting. Understanding the spatial and stratigraphic variations in ground ice distribution on permafrost slopes is therefore a fundamental property in assessing the stability of permafrost hillslopes.

The impact of Arctic sea‐ice loss on winter weather in the British Isles

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Arctic sea‐ice loss shifts the North Atlantic jet and storm track equatorward, and results in a more negative North Atlantic Oscillation and more positive East Atlantic and Scandinavian patterns. Strong extratropical cyclones weaken and become less frequent for the British Isles, but there is model disagreement for precipitation, surface winds, and ...

A sazonalidade do tromboembolismo venoso no clima subtropical de São Paulo Seasonal variation of venous thromboembolism in the subtropical climate of São Paulo, Brazil

Jornal Vascular Brasileiro, 2009
CONTEXTO: Os fatores desencadeantes da doença tromboembólica venosa vêm sendo cada vez melhor identificados. Causas externas podem influir na sua ocorrência, e algum destaque tem sido dado a fatores climáticos. Nada se sabe quanto a essa interferência em

Impacts of the East Asian monsoon on lower tropospheric ozone over coastal South China

Environmental Research Letters, 2013
The impact of the East Asian monsoon (EAM) on climatology and interannual variability of tropospheric ozone (O _3 ) over the coastal South China was investigated by analyzing 11 years of ozonesonde data over Hong Kong with the aid of Lagrangian ...

Can tropical cyclones exist near the Equator?

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Schematic showing how a developed TC responds to reduced Coriolis parameter (f). Zero‐f lowers inertial stability and increases agradient force, enhancing radial inflow at lower levels. Stronger inflow deepens the inflow layer and promotes convergence, intensifying convection and downdrafts in outer rainbands.

Air conditioning versus heating: climate control is more energy demanding in Minneapolis than in Miami

Environmental Research Letters, 2013
Energy demand for climate control was analyzed for Miami (the warmest large metropolitan area in the US) and Minneapolis (the coldest large metropolitan area). The following relevant parameters were included in the analysis: (1) climatological deviations

ERA5 deficit in supercooled liquid water cloud radiative forcing at Dome C, Antarctica

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Meteorological reanalyses from ERA5 for December from 1940 to the present have been analysed to assess the logarithmic relationship between liquid water path (LWP, liquid water profile integrated along the vertical) and supercooled liquid water (SLW, liquid water at temperatures less than 0°C) cloud radiative forcing (CRF) over Dome C, Antarctica as ...
