Ocean Meanders Modulate Extratropical Cyclone Energetics

Geophysical Research Letters
Extratropical cyclones primarily develop over the western parts of ocean basins, where strong sea surface temperature (SST) contrasts form along western boundary currents.

Phase transitions between tropical, subtropical, and extratropical cyclones: A review from IWTC-10

Tropical Cyclone Research and Review, 2023
This review, which was adapted from a Tenth International Workshop on Tropical Cyclones (IWTC-10) report, discusses research findings and operational practices relevant to cyclone types and phase transitions (extratropical, subtropical, and tropical ...

Cloud feedbacks in extratropical cyclones: insight from long-term satellite data and high-resolution global simulations [PDF]

Atmospheric Chemistry and Physics, 2019
A negative extratropical shortwave cloud feedback driven by changes in cloud optical depth is a feature of global climate models (GCMs). A robust positive trend in observed liquid water path (LWP) over the last two decades across the warming Southern ...

Extratropical cyclone statistics during the last millennium and the 21st century [PDF]

Climate of the Past, 2018
Extratropical cyclones in winter and their characteristics are investigated in depth for the Atlantic European region, as they are responsible for a significant part of the rainfall and extreme wind and/or precipitation-induced hazards.

Extratropical Cyclones: A Century of Research on Meteorology’s Centerpiece [PDF]

Meteorological Monographs, 2019
AbstractThe year 1919 was important in meteorology, not only because it was the year that the American Meteorological Society was founded, but also for two other reasons. One of the foundational papers in extratropical cyclone structure by Jakob Bjerknes was published in 1919, leading to what is now known as the Norwegian cyclone model. Also that year,

Cotes's Spiral Vortex in Extratropical Cyclone Bomb South Atlantic Oceans [PDF]

Aswan University Journal of Environmental Studies, 2020
The characteristic shape of hurricanes, cyclones, typhoons is a spiral. There are several types of turns, and determining the characteristic equation of which spiral the “cyclone bomb” (CB) fits into is the goal of the work. In mathematics, a spiral is a

Estudo de caso de ciclone extratropical sobre a América do Sul: sensibilidade das análises Case study of extratropical cyclone over the South America: sensibility of analysis

Revista Brasileira de Meteorologia, 2009
A trajetória e a energética de um ciclone extratropical são analisadas usando as reanálises do NCEP/NCAR, em comparação com as saídas do modelo CPTEC/COLA (T126L28) com análises do GPSAS.

Uncertainties in cloud-radiative heating within an idealized extratropical cyclone [PDF]

Atmospheric Chemistry and Physics
Cloud-radiative heating (CRH) within the atmosphere affects the dynamics and predictability of extratropical cyclones. However, CRH is uncertain in numerical weather prediction and climate models, and this could affect model predictions of extratropical ...

Detection and global climatology of two types of spatio-temporal clustering of extratropical cyclones [PDF]

Weather and Climate Dynamics
The swift succession of multiple extratropical cyclones during a short period of time is often associated with weather extremes and characterised by a strong atmospheric jet and enhanced baroclinicity.

New method for detecting extratropical cyclones: the eight-section slope detecting method

Atmospheric and Oceanic Science Letters, 2020
An algorithm for identifying extratropical cyclones (ECs) on the basis of gridded data is proposed in this study. The algorithm, which is named the eight-section slope detecting (ESSD) method, has five key procedures to identify an EC by using the mean ...
