The Extratropical Transition of Tropical Cyclones

2003
Abstract : To improve tropical cyclone structure and intensity prediction through a research program combining high-resolution modeling and detailed observational studies to investigate physical processes by which the structure and intensity of a tropical cyclone are modified.

Impacts of Extratropical Transition on Tropical Cyclone Tornadoes

Monthly Weather Review
The impact of extratropical transition (ET) on tropical cyclone (TC) tornadoes is not fully understood with no prior tornado climatologies for ET cases. Hence, this study investigates how ET impacts tornadoes and convective-scale environments within TCs using multidecadal tornado and radiosonde data from North Atlantic TCs.

The extratropical transition of hurricane Irene (1999): A potential‐vorticity perspective

Quarterly Journal of the Royal Meteorological Society, 2004
AbstractExtratropical transition (ET) of tropical cyclones is common in all ocean basins where tropical cyclones recurve polewards. After the tropical cyclone experiences ET, a rapid deepening can take place resulting in the development of a very large and deep extratropical cyclone. The ET of hurricane Irene (1999) was an example of such an ‘explosive’

The Comparison Study of Targeting Observation for Extratropical Transition of Hurricane Fabian

Advanced Materials Research, 2012
This study compares the propagation methods of the impact of targeted observations during the extratropical transition (ET) of Hurricane Fabian in three denial experiments. In sensitive experiment, the signal (forecast difference between denial experiments and control) propagates from the tropical cyclone (TC) to the midlatitude jet through the ...

A 40-Year Climatology of Extratropical Transition in the Eastern North Pacific

Journal of Climate, 2014
Abstract A 42-yr study of eastern North Pacific tropical cyclones (TCs) undergoing extratropical transition (ET) is presented using the Japanese 55-yr Reanalysis dataset. By using cyclone phase space (CPS) to differentiate those TCs that undergo ET from those that do not, it is found that only 9% of eastern North Pacific TCs that ...

A study of extratropical transition and re-intensification of Typhoon Mindulle (2004)

Journal of Ocean University of China, 2011
In this study, the fifth-generation Pennsylvania State University-National Center for Atmospheric Research (PSU-NCAR) Mesoscale Model (MM5) is used to simulate Typhoon Mindulle (2004) at high resolution (3-km grid size). The data from measurements show that in the upper atmosphere the existence of an upper jet is important to the transition cyclone ...

Comparison of Wave Packets Associated with Extratropical Transition and Winter Cyclones

Monthly Weather Review, 2015
Abstract Differences in the development of wave packets associated with midlatitude cyclones and the extratropical transition (ET) of tropical cyclones in the western North Pacific (WNP) and Atlantic basins are diagnosed observationally by compositing Climate Forecast System Reanalysis (CFSR) data over a 32-yr period and applying the ...

The Predictability of Extratropical Transition and of its Impact on the Downstream Flow

2006
Abstract : In this project we investigated the basic mechanisms that determine the predictability of tropical cyclones undergoing extratropical transition (ET) and of their impact on the downstream flow. The analysis of ensemble forecasts for five ET cases showed that uncertainty is associated with the location and amplitude of a characteristic upper ...

Microwave estimates of the extratropical transitions process

2012
Microwave satellite imagery is a valuable tool for the observation of mature tropical cyclones. This study examined the application of microwave data to the extratropical transition (ET) process. During ET a tropical cyclone (TC) moves into an area of large gradients in many atmospheric parameters. The data sparse regions in which these gradients exist
