Abstract Purpose of Review Atmospheric blocking events represent some of the most high-
impact weather patterns in the mid-latitudes, yet they have often been a cause for concern in …

This paper characterizes the spatiotemporal variability of air stagnation over the Euro-
Mediterranean area for the 1979–2016 period by using a simplified air stagnation index …

Atmospheric blockings and their impacts on wintertime surface air temperature in East Asia
are investigated by using three blocking indices. Blockings in two specific regions that …

Different air stagnation indices (ASIs) have been proposed to measure the atmospheric
diffusion conditions. This paper undertakes a comparative analysis of three ASIs and …

Ozone pollution and high temperatures have adverse health impacts that can be amplified
by the combined effects of ozone and temperature. Moreover, changes in weather patterns …

Spatial knowledge of the climatic or environmental variables associated with the most
frequent circulation types is essential with regard to developing strategies to address the risk …

Using a new high-resolution air quality reanalysis dataset for China for five winters from
December 2013 to February 2018, we examine the influence of large-scale circulation on …

The build-up of pollutants to harmful levels can occur when meteorological conditions favour
their production or accumulation near the surface. Such conditions can arise when a region …

We have analysed the impact of the North Atlantic jet on the winter PM 10 (particulate matter
with aerodynamic diameter≤ 10 μm) concentrations in Europe during a 10-year period. For …

Air stagnation refers to an extended period of clear, stable conditions which can favour the
accumulation of pollutants in the lower atmosphere. In Europe, weather conditions are …
