Air stagnation in Europe: Spatiotemporal variability and impact on air quality

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 (ASI) based on daily precipitation as well as near-surface and upper wind speed data. We have also undertaken the first compa...

The northern regions (SCAN and NEU), which are affected by moderately strong near-surface winds and ample precipitation, present low frequency and temporal variability in stagnation compared to the southern regions (SW and SE).

Air stagnation exerts a clear influence on air quality (AQ), with anomalies above 10% for summer ozone (O3) and 30% for winter PM10 (particulate matter ≤10 μm in diameter) on stagnant vs. non-stagnant days over most of the regions. These values exceed 20% and 50%, respectively, in the case of CEU, where air stagnation also drives significant changes in the frequency distributions of these pollutants and increases the likelihood of AQ exceedances.
