Three dominant synoptic atmospheric circulation patterns influencing severe winter haze in eastern China

Large-scale atmospheric circulation patterns associated with the occurrence of severe storms Zab basin

Atmospheric circulation patterns which promote winter Arctic sea ice decline

The impact of winter atmospheric blocking over the Ural Mountains region (UB) coincident with different phases of the North Atlantic Oscillation (NAO) on the sea ice variability over the Barents and Kara Seas (BKS) in winter is investigated. It is found that the UB in conjunction with the positive phase of the NAO (NAOþ) leads to the strongest sea ice decline. During this phase composites and t...

Winter Nighttime Temperature Inversions and Their Relationship with the Synoptic-scale Atmospheric Circulation

The present work aims at examining the association of nighttime temperature inversions and synoptic-scale circulation in the Athens basin. Temperature inversions have a direct impact in the diffusion and transport of pollutants, a fact that highlights the importance of investigating their cause effect relationship. For this purpose, randiosonde measurements from the upper-air station in Hellini...

Elucidating severe urban haze formation in China.

As the world's second largest economy, China has experienced severe haze pollution, with fine particulate matter (PM) recently reaching unprecedentedly high levels across many cities, and an understanding of the PM formation mechanism is critical in the development of efficient mediation policies to minimize its regional to global impacts. We demonstrate a periodic cycle of PM episodes in Beiji...
