Persistent heat extremes can have severe impacts on ecosystems and societies, including
excess mortality, wildfires, and harvest failures. Here we identify Europe as a heatwave …

Abstract In June–July 2020 two remarkable weather events occurred in northern Eurasia.
One is a severe heat wave that produced a record-breaking temperature of 38° C at …

The link between atmospheric blocking and propagating and breaking synoptic-scale
Rossby waves (termed PV streamers) are explored for the climatological period 1958–2002 …

The summer Northern Hemisphere annular mode (summer NAM), a new mode determined
through empirical orthogonal function (EOF) analysis for each individual calendar month …

A new block maintenance mechanism, the selective absorption mechanism (SAM), is
proposed. According to this mechanism, which is based on vortex–vortex interactions (ie, the …

Abstract In North America and Asia, extreme cold weather characterized the winter of 2017–
18. At the same time, the Pacific, the Bering Sea, and the Atlantic Arctic regions experienced …

Using reanalysis data from the National Centers for Environmental Prediction‐National
Center for Atmosperic Research, Boulder, Colorado, for the period from 1958 to 2005, we …

The cold surges over East Asia can be classified into wave-train type and blocking type
according to their dynamic origins. In the present study, two dynamic indices are proposed to …

A Causality-Based View of the Interaction between Synoptic- and Planetary-Scale
Atmospheric Disturbances in: Journal of the Atmospheric Sciences Volume 77 Issue 3 (2020) …

A new maintenance mechanism of blocking is proposed; a blocking high, which is
characterized by low potential vorticity, selectively absorbs synoptic highs, thereby …
