Bipolar Lightning Flashes Observed at the Säntis Tower: Do We Need to Modify the Traditional Classification?

Mario Paolone, Marcos Rubinstein, Mohammad Azadifar, Davide Pavanello

We present and discuss current waveforms associated with 13 bipolar lightning flashes recorded at the Santis Tower during the period from June 2010 to January 2015. During this period, a total of 427 flashes were recorded, of which 13 (3%) were classified ...

OES Characterization of Steamers in a Nanosecond Pulsed SBDB Using N2 and Ar Transitions

Christoph Hollenstein, Peter Ott, Pénélope Leyland, Philip Peschke, Sami Goekce

The characterization of non-thermal homogeneous plasmas is possible using optical emission spectroscopy (OES), notably by estimating the reduced electric field. This method was applied to characterize streamers generated by a nanosecond pulsed surface diel ...

Radiation reaction induced non-monotonic features in runaway electron distributions

Joan Decker

Runaway electrons, which are generated in a plasma where the induced electric field exceeds a certain critical value, can reach very high energies in the MeV range. For such energetic electrons, radiative losses will contribute significantly to the momentu ...

Granulation of snow: From tumbler experiments to discrete element simulations

Michael Lehning, Johan Alexandre Philippe Gaume, Betty Sovilla, Walter Steinkogler

It is well known that snow avalanches exhibit granulation phenomena, i.e., the formation of large and apparently stable snow granules during the flow. The size distribution of the granules has an influence on flow behavior which, in turn, affects runout di ...

Quantifying snowfall and avalanche release synchronization: a case study

Paolo Perona, Benoît Crouzy, Betty Sovilla, Romain Forclaz

We quantify the synchronization between snowfall and natural avalanches in relation to terrain properties at the detachment zone. We analyze field statistics of 549 avalanche events in terms of slope, aspect, timing, coordinate, and release area, identifie ...

Influence of snow cover properties on avalanche dynamics

Michael Lehning, Betty Sovilla, Walter Steinkogler

The destructive power of an avalanche depends, among other things, on the overall mass and the snow conditions in the avalanche path. So far, the knowledge on the effect of snow conditions on avalanche behavior is limited and largely qualitative. We invest ...

Analyzing Corona breakdown with a finite element-based electromagnetic solver

Juan Ramon Mosig, Michael Mattes, Francisco Edén Sorolla Rosario, Ioannis Koufogiannis

This paper demonstrates how an already developed finite element code for solving electromagnetic problems can be manipulated and simply extended so as to investigate complicated corona breakdowns. A safe criterion based on the eigenvalue analysis is used i ...

Modeling microwave/electron-cloud interaction

Michael Mattes, Francisco Edén Sorolla Rosario, Frank Zimmermann

Starting from the separate codes BI-RME and ECLOUD or PyECLOUD, we are developing a novel joint simulation tool, which models the combined effect of a charged particle beam and of microwaves on an electron cloud. Possible applications include the degradati ...
