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.

Diagnosis and Dynamics of Forecast Error Growth
Huw C. Davies,Marco Didone +1 more
TL;DR: An outline is provided of a three-component diagnostic approach for studying PV forecast error that exploits the quintessential PV concepts of quasi conservation, inversion, and attribution and provides a framework for assessing the dynamics of possible mechanisms for generating realized PV-error features.

Dynamics of Rossby Wave Packets in a Quantitative Potential Vorticity–Potential Temperature Framework
Franziska Teubler,Michael Riemer +1 more
TL;DR: In this article, a potential vorticity-potential temperature (PV-θ) framework is introduced to diagnose RWP dynamics and the amplitude evolution of individual troughs and ridges is examined.
