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.

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

Stratospheric influence on tropical cyclone evolution

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We developed a metric based on moist static energy to detect and quantify the intrusion of stratospheric air into the inner core of tropical cyclones. High‐resolution numerical simulations show that this stratospheric interaction forms warm anomalies (high‐level warm cores) in the upper troposphere.

Impacts of stratospheric aerosol injection on precipitation and winds associated with extratropical cyclones in the Southern Hemisphere

Environmental Research: Climate
This study seeks to describe the impact of Stratospheric Aerosol Injection (SAI) under climate change scenarios on precipitation and 10 m winds caused by extratropical cyclones in the Southern Hemisphere, using data from three international initiatives ...

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)

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.

Structural changes in the interannual variability of extreme autumn precipitation in eastern Spain and the weakening of synoptic forcing

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Total autumn precipitation in eastern Spain remains stable between 1950 and 2024, masking a substantial internal redistribution between ordinary and extreme rainfall. While torrential precipitation (Rp95) increases and ordinary precipitation (Ro) decreases, the extreme contribution index (Cext) shows a significant positive trend and a structural shift ...

Mediterranean cyclones are a substantial cause of damaging floods in Corsica

Communications Earth & Environment
Cyclones, whether tropical, extratropical, or of Mediterranean origin, play a crucial role in the Earth’s climate system, affecting environments and populations through strong winds, heavy rainfall, and flooding.

A new scale‐selective measure of curvature for meteorological fields

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We introduce a novel diagnostic called curvature using radial variation (CURV) that quantifies the local cyclonic or anticyclonic curvature of mean‐sea‐level pressure or geopotential height gridded fields over selected scales. A depiction of how CURV values relate to differing cyclonic curvature is shown in the figure.

Do Extratropical Cyclones Impact Synoptic‐Scale Variability of the Arctic Oscillation During Cold Season?

Geophysical Research Letters
The Arctic Oscillation (AO) is the most significant mode of sea level pressure (SLP) anomalies in the Northern Hemisphere, exhibiting significant multiple‐timescale variability from synoptic to decadal.
