On the Impact of Initial Conditions in the Forecast of Hurricane Leslie Extratropical Transition [PDF]
Atmospheric Research, 2023 Hurricane Leslie (2018) was a non-tropical system that lasted for a long time undergoing several transitions between tropical and extratropical states. Its trajectory was highly uncertain and difficult to predict. Here the extratropical transition of Leslie is simulated using the Model for Prediction Across Scales (MPAS) with two different sets of ...

The Extratropical Transition of Tropical Cyclone Lili (1996) and Its Crucial Contribution to a Moderate Extratropical Development [PDF]
Monthly Weather Review, 2005 Abstract The transition that a tropical cyclone experiences as it moves into the extratropical environment (known as extratropical transition) can result in the decay or intensification of a baroclinic cyclone. The extratropical transition (ET) of Tropical Cyclone Lili (1996) in the North Atlantic resulted in a moderate extratropical ...

Geophysical Research Letters, 2023 In this study, we investigated the changes in the origin of moisture for the precipitation associated with tropical cyclones (TCs) after extratropical transition (ET) over the North Atlantic Ocean basin from 1980 to 2018. We analyzed the 24 hr before and

The impacts of climate change on tropical-to-extratropical transitions in the North Atlantic Basin [PDF]
Weather and Climate DynamicsAs tropical cyclones migrate toward mid-latitudes, they can transform into extratropical cyclones, a process known as extratropical transition. In the North Atlantic Basin, nearly half of hurricanes undergo this transition.

Residual circulation trajectories and transit times into the extratropical lowermost stratosphere [PDF]
Atmospheric Chemistry and Physics, 2010 Abstract. Transport into the extratropical lowermost stratosphere (LMS) can be divided into a slow part (time-scale of several months to years) associated with the global-scale stratospheric residual circulation and a fast part (time-scale of days to a few months) associated with (mostly quasi-horizontal) mixing (i.e.

Tropical cyclone intensification and extratropical transition under alternate climate conditions: a case study of Hurricane Ophelia (2017) [PDF]
Weather and Climate DynamicsPost-tropical cyclones can have substantial impacts on regions unaccustomed to such powerful storms. Previous studies have found that the prevalence of such storms is expected to increase in the future.

Acceleration of tropical cyclones as a proxy for extratropical interactions: synoptic-scale patterns and long-term trends [PDF]
Weather and Climate Dynamics, 2021 It is well known that rapid changes in tropical-cyclone motion occur during interaction with extratropical waves. While the translation speed has received much attention in the published literature, acceleration has not.

On the mixing‐driven formation of the Extratropical Transition Layer (ExTL) [PDF]
Journal of Geophysical Research: Atmospheres, 2012 We present a case study on the formation and structure of the Extratropical Transition Layer (ExTL) using in situ observations and a Lagrangian chemical transport model. The results show that the model with mixing parameterized from the large‐scale flow deformations well reconstructs the observed asymmetric structure of the ExTL with a deeper ...
