WRF-Chem simulations in the Amazon region during wet and dry season transitions: evaluation of methane models and wetland inundation maps

The Amazon region, being a large source of methane (CH4), contributes significantly to the global annual CH4 budget. For the first time, a forward and inverse modelling framework on regional scale for the purpose of assessing the CH4 budget of the Amazon r ...

On the proportion of upward flashes to lightning research towers

Marcos Rubinstein, Wolfgang Schulz

We compare in this paper direct measurements obtained on the towers on San Salvatore Mountain (Switzerland) and on the Gaisberg Mountain (Austria). They are situated in similar topographical environments but in different lightning activity zones. Direct me ...

Effects of nearby buildings on lightning induced voltages on overhead power distribution lines

Mario Paolone, Carlo Alberto Nucci

For the case of urban overhead lines, the presence of nearby buildings is expected to affect the overvoltages induced by nearby cloud-to-ground lightning return strokes. So far, this effect has been seldom taken into account in the literature on the subjec ...

Convective cells and blob control in a simple magnetized plasma

Ambrogio Fasoli, Ivo Furno, Christian Gabriel Theiler, Joaquim Loizu Cisquella

Blob control by creating convective cells using biased electrodes is demonstrated in simple magnetized toroidal plasmas. A two-dimensional array of electrodes is installed on a metal limiter to obtain different biasing schemes. Detailed two-dimensional mea ...

Investigation of the unusual polarimetric signatures of a mountainous convective event

Alexis Berne, Jacopo Grazioli

A case study of an intense convective event occurring in the Swiss Alps (Davos) is presented. Polarimetric X-band observations of this event showed an unusual strong signature in terms of differential reflectivity Zdr, differential phase shift on backscatt ...

Properties of convective cells generated in magnetized toroidal plasmas

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Christian Gabriel Theiler, Joaquim Loizu Cisquella

Convective cells for turbulence control, generated by means of biased electrodes, are investigated in the simple magnetized toroidal plasmas of TORPEX. A two-dimensional array of 24 electrodes is installed on a metal limiter to test different biasing schem ...

Stochastic simulation of intermittent DSD fields in time

Alexis Berne, Marc Schleiss, Joël Jaffrain

A method for the stochastic simulation of (rain)drop size distributions (DSDs) in space and time using geostatistics is presented. At each pixel, the raindrop size distribution is described by a Gamma distribution with two or three stochastic parameters. T ...

Stochastic space-time disaggregation of rainfall into DSD fields

Alexis Berne, Marc Schleiss

A stochastic method to disaggregate rainfall fields into DSD fields is proposed. It is based on a previously presented DSD simulator that has been modified in order to take into account imposed mean values provided at the coarser scale. The integral quanti ...

Influence of the DSD variability at the radar subgrid scale on radar power laws

Alexis Berne, Joël Jaffrain

Power laws relating the different radar observables (from conventional or polarimetric radar systems) are commonly used in the processing of radar measurements (e.g., attenuation correction) and in their conversion into rain rate values (e.g., Z-R relation ...

Improving Alpine Flood Prediction through Hydrological Process Characterization and Uncertainty Analysis

Cara Christine Tobin

Among the many challenges of Alpine flood prediction is describing complex, meteo-hydrological processes in a simplified, robust manner that can be easily integrated into operational forecasting. In this dissertation, improved methods to characterize these ...
