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.

Climatological Changes in the Extratropical Transition of Tropical Cyclones in High-Resolution Global Simulations
TL;DR: Tropical cyclones undergoing extratropical transition (ET) can develop into intense cyclonic systems accompanied by high-impact weather in areas far removed from the original TC as mentioned in this paper.

How an uncertain short-wave perturbation on the North Atlantic wave guide affects the forecast of an intense Mediterranean cyclone (Medicane Zorbas)
TL;DR: In this paper, the authors exploited a European Centre for Medium-Range Weather Forecasts (ECMWF) operational ensemble forecast with an uncertain potential vorticity (PV) streamer position over the Mediterranean that, 3'd after initialization, resulted in an uncertain development of the Mediterranean tropical-like cyclone (Medicane) Zorbas in September 2018.

The Generation of Global Rotational Flow by Steady Idealized Tropical Divergence
TL;DR: In this paper, a vorticity equation model is used to diagnose the relationship between tropical convective heating and the upper tropospheric rotational wind field, and it is shown that the Rossby wave source can be very different from the simple −fD source often used.

TL;DR: In this paper, a new algorithm is applied to study water vapor fluxes in the troposphere using wind and moisture data from the European Centre for Medium-Range Weather Forecasts.

Two paradigms of baroclinic‐wave life‐cycle behaviour
TL;DR: In this paper, two idealized baroclinic wave-6 life cycles examined here suggest a framework of opposite extremes (a) in which to view the behaviour of real synoptic-scale disturbances in middle latitudes, and b) in contrast, using the saturation-propagation-saturation (SPS) picture of wave 6 life-cycle behaviour.

TL;DR: The Subseasonal to Seasonal (S2S) Prediction research project has been established by the World Weather Research Programme/World Climate Research Programme as discussed by the authors, which is the main deliverable of this project is the establishment of an extensive database containing sub-seasonal (up to 60 days) forecasts, 3 weeks behind real time, and reforecasts from 11 operational centers, modeled in part on the The Observing System Research and Predictability Experiment (THORPEX) Interactive Grand Global Ensemble (TIGGE) database for medium-range forecasts.

Potential Vorticity Diagnostics of Cyclogenesis
TL;DR: In this paper, a diagnostic system based on the relative smallness of the irrotational part of the horizontal wind was developed to calculate the balanced flow given the three-dimensional distribution of Ertel's potential vorticity (PV) framework.
