Wave-like Spiral Interactions and the Emergence of Quasi-Biennial Oscillations in Strato-Rotational Flows
Gabriel Meletti, Stéphane Abide, Stéphane Viazzo +2
This study investigates the dynamics of Strato-Rotational Instability (SRI) in a stratified, rotating fluid, focusing on the interaction between axial modes and spiral components.…
Building transport models from baroclinic wave experimental data
M. Agaoglou, V. J. Garcia-Garrido, U. Harlander +1
In this paper we study baroclinic waves both from the experimental and the theoretical perspective. We obtain data from a rotating annulus experiment capable of producing a series…
On the influence of the heat transfer at the free surface of a thermally-driven rotating annulus
Gabriel Meletti, Stéphane Abide, Uwe Harlander +2
Experiments on rotating annuli that are differentially heated in the radial direction have been largely contributing to a better understanding of baroclinic instabilities. This con…
Localized layers of turbulence in stratified horizontally sheared Poiseuille flow
Joris Labarbe, Patrice Le Gal, Uwe Harlander +2
This article presents a numerical analysis of the instability developing in horizontally sheared Poiseuille flow, when stratification extends along the vertical direction. Our stud…
Extreme events in a polar warming scenario--a laboratory perspective
Costanza Rodda, Uwe Harlander, Miklos Vincze
We report on a set of laboratory experiments to investigate the effect of Arctic warming on the amplitude and drift speed of the mid-latitude jet stream. Our results show that a pr…
Experiments and long-term High Performance Computations on amplitude modulations of strato-rotational flows
G. Meletti, S. Abide, S. Viazzo +2
The present paper describes a combined experimental and high performance computing study of new specific behaviors of the Strato-Rotational Instability (SRI). The confrontation of…
Transition from geostrophic flows to inertia-gravity waves in the spectrum of a differentially heated rotating annulus experiment
Costanza Rodda, Uwe Harlander
Inertia-gravity waves (IGWs) play an essential role in the terrestrial atmospheric dynamics as they can lead to energy and momentum flux when propagating upwards. An open question…
A study of turbulence and interacting inertial modes in a differentially-rotating spherical shell experiment
Michael Hoff, Uwe Harlander, Santiago A. Triana
We present a study of inertial modes in a differentially rotating spherical shell (spherical Couette flow) experiment with a radius ratio of . Inertial modes are Coriolis-r…
Temperature fluctuations in a changing climate: an ensemble-based experimental approach
Miklos Vincze, Ion Borcia, Uwe Harlander
There is an ongoing debate in the literature about whether the present global warming is increasing local and global temperature variability. The central methodological issues of t…
The stratorotational instability of Taylor-Couette flows of moderate Reynolds numbers
G. Rüdiger, T. Seelig, M. Schultz +3
In view of new experimental data the instability against adiabatic nonaxisymmetric perturbations of a Taylor-Couette flow with an axial density stratification is considered in depe…
Double-diffusive convection and baroclinic instability in a differentially heated and initially stratified rotating system: the barostrat instability
Miklos Vincze, Ion Borcia, Uwe Harlander +1
A water-filled differentially heated rotating annulus with initially prepared stable vertical salinity profiles is studied in the laboratory. Based on two-dimensional horizontal pa…
Taylor-Couette turbulence at radius ratio : scaling, flow structures and plumes
Roeland C. A. van der Veen, Sander G. Huisman, Sebastian Merbold +4
Using high-resolution particle image velocimetry we measure velocity profiles, the wind Reynolds number and characteristics of turbulent plumes in Taylor-Couette flow for a radius…
Benchmarking in a rotating annulus: a comparative experimental and numerical study of baroclinic wave dynamics
Miklos Vincze, Sebastian Borchert, Ulrich Achatz +11
The differentially heated rotating annulus is a widely studied tabletop-size laboratory model of the general mid-latitude atmospheric circulation. The two most relevant factors of…
An experimental study of regime transitions in a differentially heated baroclinic annulus with flat and sloping bottom topographies
Miklos Vincze, Uwe Harlander, Thomas von Larcher +1
A series of laboratory experiments has been carried out in a thermally driven rotating annulus to study the onset of baroclinic instability, using horizontal and uniformly sloping…
