This chapter assesses the state of physical, biological and social knowledge concerning the
Arctic and Antarctic ocean and cryosphere, how they are affected by climate change, and …

Recent boreal winters have exhibited a large-scale seesaw temperature pattern
characterized by an unusually warm Arctic and cold continents. Whether there is any …

CERA‐20C is a coupled reanalysis of the twentieth century which aims to reconstruct the
past weather and climate of the Earth system including the atmosphere, ocean, land, ocean …

This chapter assesses the state of physical, biological and social knowledge concerning the
Arctic and Antarctic ocean and cryosphere, how they are affected by climate change, and …

We propose a novel approach to the study of compound extremes, grounded in dynamical
systems theory. Specifically, we present the co‐recurrence ratio (α), which elucidates the …

A number of studies have investigated the large‐scale drivers and upstream precursors of
extreme weather events, making it clear that the earliest warning signs of extreme events …

The Arctic stratospheric polar vortex is an important driver of mid-latitude cold spells. One
proposed coupling mechanism between the stratospheric polar vortex and the troposphere …

Understanding and predicting midlatitude cold spells is of scientific and public interest, given
often associated severe impacts. However, large-scale atmospheric dynamics related to …

Atmospheric dynamics are described by a set of partial differential equations yielding an
infinite-dimensional phase space. However, the actual trajectories followed by the system …
