Potential vorticity is among the most important scalar quantities in atmospheric dynamics. For instance, potential vorticity plays a key role in particularly strong wind peaks in extratropical cyclones and it is able to explain the occurrence of frontal rain bands. Potential vorticity combines the key quantities of atmospheric dynamics, namely rotation and stratification. Under suitable wind conditions elongated banners of potential vorticity appear in the lee of mountains. Their role in… Expand
Implicit Ray Casting of the Parallel Vectors Operator
This work uses a GPU volume rendering framework to calculate the lines on-the-fly via a parallel vectors implementation in the volume rendering kernels, and achieves real-time performance for the feature curve extraction, which enables interactive filtering and parameter adjustment. Expand


The Missing Link between Terrain-Induced Potential Vorticity Banners and Banded Convection
AbstractOn 1 February 2014, the southern side of the Alps was affected by a severe snowstorm that forced authorities to issue the highest level of avalanche danger in southern parts of Austria. TheExpand
Low-Level Potential Vorticity and Cyclogenesis to the Lee of the Alps
Abstract High-resolution numerical model simulations over the Alpine region are presented that reveal the presence of low-level elongated bands of potential vorticity (PV) downstream of highExpand
Robust Detection and Visualization of Jet-Stream Core Lines in Atmospheric Flow
A method is proposed that exploits directional information in the wind field to extract core lines in a robust and numerically less involved manner than traditional 3D ridge detection and is applied to meteorological analysis for the first time. Expand
Structure and dynamics of an Alpine potential‐vorticity banner
A detailed analysis is undertaken of the primary Alpine shear zone that occurred on 1 October 1999 during the Mesoscale Alpine Programme. This shear zone emanates from the south-western Alpine tip inExpand
On the use and significance of isentropic potential vorticity maps
The two main principles underlying the use of isentropic maps of potential vorticity to represent dynamical processes in the atmosphere are reviewed, including the extension of those principles toExpand
Global Climatologies of Eulerian and Lagrangian Flow Features based on ERA-Interim
AbstractThis paper introduces a newly compiled set of feature-based climatologies identified from ERA-Interim (1979–2014). Two categories of flow features are considered: (i) Eulerian climatologiesExpand
The State of the Art in Vortex Extraction
An overview over the advances that have been made in the analysis of vortices in the last 40 years is provided, providing sufficient background on differential vector field calculus, extraction techniques like critical point search and the parallel vectors operator, and the notion of reference frame invariance is introduced.

The Real-Time Ultrafinescale Forecast Support during the Special Observing Period of the MAP
Recent developments in numerical modeling and computer technology will soon allow for limited-area production-type numerical weather prediction at a resolution of 1–2 km. This advance opens excitingExpand
Conditional symmetric instability - a possible explanation for frontal rainbands
In order to study the possible importance of symmetric baroclinic instability in the formation of frontal rainbands, the existing theory is reviewed and the inclusion of the effects of latent heatExpand
Convective Snowbands Downstream of the Rocky Mountains in an Environment with Conditional, Dry Symmetric, and Inertial Instabilities
Abstract Convective snowbands moved slowly over Wyoming and northern Colorado on 16–17 February 2007 and produced up to 71 mm (2.8 in.) of snow that was unpredicted by operational numerical weatherExpand
