Investigating the inability of climate models to reproduce observed increases in summer Greenland Blocking Open
Summertime atmospheric blocking over Greenland promotes melting of the Greenland ice sheet, which is known to be a major contributor to sea level rise. In the early twenty-first century, strong, persistent Greenland blocking was observed, …

Using seasonal forecasts to enhance our understanding of extreme wind and precipitation impacts from extratropical cyclones Open
Considerable effort is spent at insurance and reinsurance companies to estimate the risk posed by extratropical cyclones (ETCs). Among these risks, strong near surface wind speeds and heavy precipitation can be particularly damaging, threa…

Greenland summer blocking characteristics: an evaluation of a high-resolution multi-model ensemble Open
Atmospheric blocking is a phenomenon that can lead to extreme weather events over a large region, yet its causes are not fully understood. Global climate models show limitations in representing Northern Hemisphere blocking, especially its …

Missing Increase in Summer Greenland Blocking in Climate Models Open
Summertime Greenland blocking (GB) can drive melting of the Greenland ice sheet, which has global implications. A strongly increasing trend in GB in the early twenty‐first century was observed but is missing in climate model simulations. H…

Added value of a multiparametric eddy-driven jet diagnostic for understanding European air stagnation Open
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 strongly mediated by the North Atlantic eddy-driven jet stre…

Estimating worst-case European windstroms, and worst-case seasons, using seasonal forecasts. Open
Windstorms pose continual risk to Europe. Among their associated hazards, strong near-surface winds can be particularly damaging, threatening infrastructure, life and billions of pounds in insured losses. Insurers (and reinsurers) therefor…

Assessing the Projected Changes in European Air Stagnation due to Climate Change Open
Air pollution is a major environmental threat to human health. Pollutants can reach extreme levels in the lower atmosphere when weather conditions permit. As pollutant concentrations depend on scales and processes that are not fully repres…

Linking air stagnation in Europe with the synoptic- to large-scale atmospheric circulation Open
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 experiences air stagnation. The link between European a…

Upstream Cyclone Influence on the Predictability of Block Onsets over the Euro-Atlantic Region Open
Atmospheric blocking has been shown to be a phenomenon that models struggle to predict accurately, particularly the onset of a blocked state following a more zonal flow. This struggle is, in part, due to the lack of a complete dynamical th…

Downstream influence on Rossby wave breaking and blocking by extratropical cyclones Open
An atmospheric block is a weather event characterised by a large-amplitude tropospheric ridge of high pressure that is synoptic in scale and can persist over a region for several weeks. Such blocks, occur frequently in the midlatitudes of …
