Using satellite data and reanalysis to evaluate the representation of diabatic processes in extratropical cyclones in a climate model

, 2016
This is an open access article.Extratropical cyclones are a key feature of the weather in the extra-tropics, which climate models need to represent in order to provide reliable projections of future climate.

The impacts of climate change on tropical-to-extratropical transitions in the North Atlantic Basin [PDF]

Weather and Climate Dynamics
As tropical cyclones migrate toward mid-latitudes, they can transform into extratropical cyclones, a process known as extratropical transition. In the North Atlantic Basin, nearly half of hurricanes undergo this transition.

Representation of Extratropical Cyclones, Blocking Anticyclones, and Alpine Circulation Types in Multiple Reanalyses and Model Simulations [PDF]

, 2018
Atmospheric circulation types, blockings, and cyclones are central features of the extratropical flow and key to understanding the climate system. This study intercompares the representation of these features in 10 reanalyses and in an ensemble of 30 ...

Flying through extratropical cyclone Friedhelm [PDF]

Weather, 2013
On 8 December 2011, Cyclone Friedhelm, an explosively deepening cyclone, passed across the UK, causing exceptionally strong winds over Scotland and strong winds over much of the UK. A research flight through this intense cyclone was undertaken as part of the DIAMET project.

How consistently do ensemble prediction systems represent the growth of atmospheric uncertainty?

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Spread‐based diagnostics calculated for 12 ensemble prediction systems are compared to understand the consistency with which they represent atmospheric uncertainty growth. Good correlation between all these systems is found in the extratropics for a lead time range from 48 hr to between 96 hr and 192 hr.

Fewer deep cyclones projected for the midlatitudes in a warming climate, but with more intense rainfall

Environmental Research Letters, 2021
Cyclones are a major cause of extreme weather in the extratropics. Projections of future climate change have focussed on extratropical cyclones identified close to the surface, but cyclones identified at multiple levels of the atmosphere (‘deep’ cyclones)

The Dissipation Structure of Extratropical Cyclones

Journal of the Atmospheric Sciences, 2013
Abstract The physical characteristics of extratropical cyclones are investigated based on nonequilibrium thermodynamics. Nonequilibrium thermodynamics, using entropy as its main tool, has been widely used in many scientific fields. The entropy balance equation contains two parts: the internal entropy production corresponds to dissipation

A multimodel intercomparison study of variable‐resolution global models with grid refinement over the Arctic and Antarctic

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We document the protocol and first results from the first ever coordinated multimodel variable‐resolution experiment set with refinement over the polar regions. We find that the refinement generally yields model‐dependent effects. The most consistent improvement is an amelioration of the upper‐level cold bias in the polar regions that translates into ...

nfluence of Global Warming on The Trajectories and Intensities of Extratropical Cyclones in the Southern Hemisphere [PDF]

Anuário do Instituto de Geociências, 2018
Extratropical cyclones and your preferred range of operation “storm tracks” play a key role in the global energy system, especially in regions of high latitudes.

Characterization of synoptic environment for mesoscale convective systems over South Korea using ERA5 reanalysis data

Quarterly Journal of the Royal Meteorological Society, EarlyView.
In this study, the synoptic conditions for modes of mesoscale convective systems (MCSs) in South Korea are generalized based on composite analysis. The preferred precipitation region, synoptic patterns, moisture transport, sea surface temperature and thermodynamic and dynamic instabilities are characterized according to four modes: convective cells (CC)
