Short summary
This paper presents a new large ensemble of climate model simulations: The CANARI HadGEM3 Large Ensemble (CANARI LE). The CANARI LE has a comparatively high resolution, provides sub-daily output on atmospheric pressure levels, and boundary conditions for driving regional model simulations. The CANARI LE is thus a community resource that lends itself for the study of physical coupled climate processes, weather systems, and impacts in a changing climate.

Storm Daniel led to severe flooding in Greece and Bulgaria, followed by a catastrophic flood in Derna, Libya. We establish that the event was difficult to predict because small errors in the track of Hurricane Franklin over the Atlantic several days earlier grew into large differences in forecasts over Europe. This study highlights the need for improved operational global weather forecasts and raises awareness of the early warning signs that can lead to high-impact weather.

This paper describes a new dataset for the study of historical tropical cyclones. RABTracks is a global dataset that combines official tropical cyclone records with multiple weather reanalyses and tracking methods from 1940 to today. It extends cyclone tracks before formation and after dissipation, adding information on intensity, size, structure, and transition to extratropical storms. The dataset is designed to support improved cyclone risk analysis.

We examined how a marine heatwave - period of unusually warm ocean conditions - affected flooding and coastal erosion during a storm in northwest Europe. Using a state-of-the-art regional coupled model at km-scale, we compared simulations with and without the marine heatwave to isolate its effects on the storm hazards. Warmer shallow seas intensified rainfall, winds and surface depression of the storm, which integrated into larger increases of surge, wave power and river flows.

Sting jets are air flows that can form in cloudy and unstable regions of intense windstorms. They can cause damaging wind gusts as they descend and accelerate while releasing their instability. We use a numerical simulation of Storm Ciarán to identify the individual cloud processes, such as condensation and sublimation, driving the onset of this instability. We reveal their complex interplay and highlight the unique properties of the three-dimensional environment in which a sting jet develops.

Short summary
The strength of the North Atlantic storm track, a region where cyclones develop and propagate, is determined by the north to south temperature gradient across the storm track. The usual measure of this strength is the Eady growth rate, which encodes relevant information about the structure of wind and temperature. In this manuscript we show that this rather complex measure can be reduced to a much simplified expression while maintaining its accuracy.

An initial estimate of sea ice conditions are required to start modern weather forecasting models. To get these we have to combine observations, typically from satellites, with previous estimates of the sea ice conditions. This paper talks about how we do this in the latest version of the model, where the sea ice state has to be specified for ice of different thicknesses. We describe the method that is used when we produce an estimate for every hour for the past 50 years.

The socio-economic risk represented by mid-latitude cyclones in Europe is changing in a warming climate, but these changes are not uniform across all cyclones. Here we investigate climate change effects on contrasting historical cyclones that impacted the UK. We show that the changes in likelihood, intensity and causes do depend on each cyclone’s characteristics. This highlights that accounting for cyclone-specific responses is critical for assessing impacts and developing adaptation strategies.

Short summary
Detailed global climate model simulations have been created based on a numerical weather prediction model, offering more accurate spatial detail down to the scale of individual cities ("kilometre-scale") and a better understanding of climate phenomena such as atmospheric storms, whirls in the ocean, and cracks in sea ice. The new model aims to provide globally consistent information on local climate change with greater precision, benefiting environmental planning and local impact modelling.

Sting jets occur in some of the most damaging cyclones impacting Europe. We present the first climatology of sting-jet cyclones over the major ocean basins. Cyclones with sting-jet precursors occur over the North Atlantic, North Pacific, and Southern Oceans, with implications for wind warnings. Precursor cyclones have distinct characteristics, even in reanalyses that are too coarse to fully resolve sting jets, evidencing the climatological consequences of strong diabatic cloud processes.

Medicane Ianos was a very intense cyclone that led to harmful impacts over Greece. We explore what processes are important for the forecasting of Medicane Ianos, with the use of the Met Office weather model. There was a preceding precipitation event before Ianos’s birth, whose energetics generated a bubble in the tropopause. This bubble created the necessary conditions for Ianos to emerge and strengthen, and the processes are enhanced in simulations with a warmer Mediterranean Sea.

We examine a Borneo vortex case using computer simulations and satellite observations. The vortex is identified with high humidity through the atmosphere and has heaviest rainfall on its northern flank. Simulations represent circulation and rainfall accumulation well. The low-level Borneo vortex is coupled with a higher-level wave, which moves westwards along a layer with a sharp vertical gradient in moisture. Vortex growth occurs through mechanisms usually considered outside the tropics.

Short summary
A recent drive to develop seamless forecasting systems has culminated in the development of weather forecasting systems that include a coupled representation of the atmosphere, ocean and sea ice. Before this, sea ice and sea surface temperature anomalies were typically fixed throughout a given forecast. We show that the dynamic coupling is most beneficial during periods of rapid ice advance, where persistence is a poor forecast of the sea ice and leads to large errors in the uncoupled system.

In this study we analyse the complex seasonal evolution of the East Asian summer monsoon. Using reanalysis data, we show the importance of the interaction between tropical and extratropical air masses converging at the monsoon front, particularly during its northward progression. The upper-level flow pattern (e.g. the westerly jet) controls the balance between the airstreams and thus the associated rainfall. This framework provides a basis for studies of extreme events and climate variability.

It is unclear how the atmosphere will respond to a retreat of summer Arctic sea ice. Much attention has been paid so far to weather extremes at mid-latitude and in winter. Here we focus on the changes in extremes in surface air temperature and precipitation over the Arctic regions in summer during and following abrupt sea ice retreats. We find that Arctic sea ice loss clearly shifts the extremes in surface air temperature and precipitation over terrestrial regions surrounding the Arctic Ocean.

This research demonstrates, using feature identification and tracking, that anticlockwise rotating vortices at about 7 km altitude called tropopause polar vortices frequently interact with storms developing in the Arctic region, affecting their structure and where they occur. This interaction has implications for the predictability of Arctic weather, given the long lifetime but a relatively small spatial scale of these vortices compared with the density of the polar observation network.

Short summary
The interaction between Arctic cyclones and the sea ice surface in summer is investigated by analysing the friction and sensible heat flux processes acting in two cyclones with contrasting evolution. The major finding is that the effects of friction on cyclone strength are dependent on a particular feature of cyclone structure: whether they have a warm or cold core during growth. Friction leads to cooling within both cyclone types in the lower atmosphere, which may contribute to their longevity.
The interaction between Arctic cyclones and the sea ice surface in summer is investigated by...
