Sudden stratospheric warmings (SSWs) are impressive fluid dynamical events in which
large and rapid temperature increases in the winter polar stratosphere (∼ 10–50 km) are …

Understanding the influence of solar variability on the Earth's climate requires knowledge of
solar variability, solar‐terrestrial interactions, and the mechanisms determining the response …

Abstract The Northern Hemisphere (NH) polar winter stratosphere of 2019/2020 featured an
exceptionally strong and cold stratospheric polar vortex. Wave activity from the troposphere …

The stratosphere can have a significant impact on winter surface weather on subseasonal to
seasonal (S2S) timescales. This study evaluates the ability of current operational S2S …

Severe cold air outbreaks have significant impacts on human health, energy use,
agriculture, and transportation. Anomalous behavior of the Arctic stratospheric polar vortex …

This second edition brings this definitive book completely up to date with the many advances
in our understanding of Arctic climate since the first edition was published in 2005. The book …

A strong link exists between stratospheric variability and anomalous weather patterns at the
earth's surface. Specifically, during extreme variability of the Arctic polar vortex termed a …

Teleconnections between the Quasi Biennial Oscillation (QBO) and the Northern
Hemisphere zonally averaged zonal winds, mean sea level pressure (mslp) and tropical …

Extreme variability of the winter‐and spring‐time stratospheric polar vortex has been shown
to affect extratropical tropospheric weather. Therefore, reducing stratospheric forecast error …

In the past several decades, the tropospheric westerly winds in the Southern Hemisphere
have been observed to accelerate on the poleward side of the surface wind maximum. This …
