RISThe Key Role of Diabatic Outflow in Amplifying the Midlatitude Flow: A Representative Case Study of Weather Systems Surrounding Western North Pacific Extratropical Transition
Publisher: American Meteorological Society
Abstract: ecurving tropical cyclones (TCs) undergoing extratropical transition (ET) may substantially modify the large-scale midlatitude flow pattern. This study highlights the role of diabatic outflow in midlatitude flow amplification ...

Rossby Wave Initiation by Recurving Tropical Cyclones in the Western North Pacific
Publisher: American Meteorological Society
Abstract: AbstractThe interaction of recurving tropical cyclones (TCs) with midlatitude Rossby waves during extratropical transition (ET) can significantly alter the midlatitude flow configuration. This study provides a climatological ...

A Phase Locking Perspective on Rossby Wave Amplification and Atmospheric Blocking Downstream of Recurving Western North Pacific Tropical Cyclones
Publisher: American Meteorological Society
Abstract: The extratropical transition (ET) of tropical cyclones (TCs) can significantly influence the evolution of the midlatitude flow. However, the interaction between recurving TCs and upstream upper-level troughs features a ...
The Climatological Impact of Recurving North Atlantic Tropical Cyclones on Downstream Extreme Precipitation Events
Publisher: American Meteorological Society
Abstract: AbstractThis study provides the first climatological assessment of the impact of recurving North Atlantic tropical cyclones (TCs) on downstream precipitation extremes. The response is evaluated based on time-lagged composites ...

Global climatologies of Eulerian and Lagrangian flow features based on ERA-Interim reanalyses
Publisher: American Meteorological Society
Abstract: his paper introduces a newly compiled set of feature-based climatologies identified from ERA-Interim reanalyses (1979?2014). Two categories of flow features are considered: (i) Eulerian climatologies of jet streams, ...
Enhanced Tropospheric Wave Forcing of Two Anticyclones in the Prephase of the January 2009 Major Stratospheric Sudden Warming Event
Publisher: American Meteorological Society
Abstract: ropospheric forcing of planetary wavenumber 2 is examined in the prephase of the major stratospheric sudden warming event in January 2009 (MSSW 2009). Because of a huge increase in Eliassen?Palm fluxes induced mainly by ...
