Moisture analysis of an extratropical cyclone [PDF]

Archiv für Meteorologie, Geophysik und Bioklimatologie Serie A, 1969
The atmospheric water balance and precipitation regime of a moving cyclone are described. The coordinate system chosen is one that moves with the traveling storm system. The computation of the atmospheric water balance is done to yield the parameter precipitation minus evaporation as a residual.

A mechanism of stratospheric O₃ intrusion into the atmospheric environment: a case study of the North China Plain [PDF]

Atmospheric Chemistry and Physics
Stratosphere-to-troposphere transport results in the stratospheric intrusion (SI) of O3 into the free troposphere through the folding of the tropopause.

Strong winds in extratropical cyclones [PDF]

The Open Atmospheric Science Journal, 2015
This thesis was funded by the Natural Environment Research Council (NERC) and is presented in an alternative thesis format. The thesis consists of three separate journal articles which form a coherent research project.Paper 1 investigates the development of strong winds in a dry, idealised extratropical cyclone using the horizontal momentum equation ...

A Record‐Breaking Cyclone Over the Southern Ocean in 2022

Geophysical Research Letters, 2023
In October 2022, an extreme cyclone developed in the South Pacific Ocean with a sea level pressure of 900 hPa, becoming the strongest extratropical cyclone in the satellite era.

Stratospheric influence on the winter North Atlantic storm track in subseasonal reforecasts [PDF]

Weather and Climate Dynamics
Extreme stratospheric polar vortex events, such as sudden stratospheric warmings (SSWs) or extremely strong polar vortex events, can have a significant impact on surface weather in winter.

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.

Weather Patterns Associated With Coastal Disasters in Santa Catarina, Southern Brazil

International Journal of Climatology, EarlyView.
The study identified weather patterns (WPs) associated with coastal disasters between 1998 and 2020 along the Santa Catarina coast, Brazil. Using atmospheric and oceanographic data combined with official disaster records, five WPs were defined, mainly associated with cyclonic and anticyclonic systems linked to extreme wave events.

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

Does vertical wind shear increase tropical cyclone rain?

Quarterly Journal of the Royal Meteorological Society, EarlyView.
A 26‐year modern precipitation dataset is used to systematically assess tropical cyclone (TC) rainfall responses to vertical wind shear (VWS). VWS enhances rainfall volume in TCs by up to 23%, despite reducing storm intensity, revealing a trade‐off where VWS mitigates wind damage but potentially amplifies flood risk.

Objective Algorithm for Detection and Tracking of Extratropical Cyclones in the Southern Hemisphere

Atmosphere
In this study, we propose an easy and robust algorithm to identify and track extratropical cyclone events using 850 hPa relative vorticity data, gaussian filter and connected-component labeling technique, which recognize the cyclone as areas under a ...
