Development of Frontal Boundaries During the Extratropical Transition of Tropical Cyclones

Quarterly Journal of the Royal Meteorological Society
AbstractThis study seeks to characterize the development of atmospheric fronts during the extratropical transition (ET) of tropical cyclones (TCs) as a function of their evolution during ET. Composite histograms indicate that the magnitude of the lower atmospheric frontogenesis and average sea‐surface temperature is different based on the nature of the

Towards Dynamical Seasonal Forecast of Extratropical Transition in the North Atlantic

Geophysical Research Letters, 2018
Extratropical transition can extend the threat of tropical cyclones into the midlatitudes and modify it through expansion of rainfall and wind fields. Despite the scientific and socioeconomic interest, the seasonal forecast of extratropical transition ...

Extratropical Transition of Hurricane Michael: An Aircraft Investigation

Bulletin of the American Meteorological Society, 2004
In order to better understand the behavior and impacts of tropical cyclones undergoing extratropical transition (ET), the Meteorological Service of Canada (MSC) conducted a test flight into Hurricane Michael. Between 16 and 19 October 2000 the transition of Hurricane Michael from a hurricane to an intense extratropical storm was investigated using a ...

Characterization of Extratropical Transition Using Cluster Analysis

Monthly Weather Review, 2004
Abstract The extratropical transition (ET) of tropical cyclones in the North Atlantic basin is explored using the framework of the Cyclone Phase Space (CPS). Analyses from the U.S. Navy Operational Global Atmospheric Prediction System (NOGAPS) and National Centers for Environmental Prediction Aviation Model (AVN) are used to diagnose CPS locations of ...

A process based definition of the extratropical transition layer

2023
The existence of the extratropical transition layer (ExTL) still lacks a physical process based explanation. It is yet an empirical finding based on the observed gradient changes of species within the lowermost stratosphere (LMS). The trace gas distribution directly results from localized and transient dynamical processes in the tropopause region ...

A Climatology of the Extratropical Transition of Atlantic Tropical Cyclones

Journal of Climate, 2001
Abstract A comprehensive climatology of extratropically transitioning tropical cyclones in the Atlantic basin is presented. Storm tracks and intensities over a period from 1899 to 1996 are examined. More detailed statistics are presented only for the most reliable period of record, beginning in 1950.

Simulations of the Transformation Stage of the Extratropical Transition of Tropical Cyclones

Monthly Weather Review, 2001
Abstract The physical mechanisms associated with the transformation stage of the extratropical transition of a tropical cyclone are simulated with a mesoscale model using initial environmental conditions that approximate the mean circulations defined by Klein et al. The tropical cyclone structural changes simulated by the U.S.

Extratropical transition of tropical cyclones in the North Atlantic

2006
Apart from a few early case studies that documented tropical cyclones (TCs) that tracked into the extratropics, it was generally accepted through the 1970s that TCs would decay as they moved out of the tropics. This preconception was challenged in the 1980s.

Hurricane Vortex Dynamics during Atlantic Extratropical Transition

Journal of the Atmospheric Sciences, 2008
AbstractSimulations of six Atlantic hurricanes are diagnosed to understand the behavior of realistic vortices in varying environments during the process of extratropical transition (ET). The simulations were performed in real time using the Advanced Research Weather Research and Forecasting (WRF) model (ARW), using a moving, storm-centered nest of ...
