TL;DR: The North Atlantic Waveguide and Downstream Impact Experiment (NAWDEX) explored the impact of diabatic processes on disturbances of the jet stream and their influence on downstream high-impact weather through the deployment of four research aircraft, each with a sophisticated set of remote-sensing and in situ instruments, and coordinated with a suite of ground-based measurements as discussed by the authors.

TL;DR: The extratropical transition (ET) of tropical cyclones often has an important impact on the nature and predictability of the midlatitude flow of the tropical cyclone as discussed by the authors.

Tropopause-Level Waveguides
TL;DR: In this article, the detection and examination of the along-flow extent and lateral confinement of the waveguides on the dynamic tropopause (i.e., iso-PV surface) and on Tropopause-cutting isentropic surfaces are given.

A Global Climatology of Tropical Moisture Exports
TL;DR: In this paper, a 6-hourly European Centre for Medium-Range Weather Forecasts (ECMWF) Interim Reanalysis (ERA-Interim) data from 1979 to 2010 instead of the earlier 40-yr ECMWF Re-Analysis (ERA40) was used.

The Role of Typhoon Songda (2004) in Producing Distantly Located Heavy Rainfall in Japan
TL;DR: In this paper, the Advanced Research version of the Weather Research and Forecast (WRF-ARW) model was used to investigate the possible remote effects of Typhoon Songda on this heavy precipitation event in Japan.
Simulations of the Extratropical Transition of Tropical Cyclones
TL;DR: In this paper, the authors simulated the impact of the strength of the midlatitude circulation trough without changing its phasing with the tropical cyclone and found that the peak intensity of the extratropical cyclone following the extarropical transition is strongly dependent on the phasing, which leads to different degrees of interaction with the mid-latitude baroclinic zone.
Journal ArticleDOI
The downstream impact of tropical cyclones on a developing baroclinic wave in idealized scenarios of extratropical transition
TL;DR: In this paper, an idealized scenario of extratropical transition (ET) is investigated by comparing and analyzing two numerical baroclinic-wave experiments: a traditional experiment in which barocliic development is excited by a localized upper-level perturbation on a realistic jet profile and an experiment in that, additionally, a model tropical cyclone is inserted south of the jet at the initial time.
