| Zusammenfassung |
| The PEACH project (Projet en Electricité Atmosphérique pour la
Campagne HyMeX – the Atmospheric Electricity Project of the HyMeX Program)
is the atmospheric electricity component of the Hydrology cycle in the
Mediterranean Experiment (HyMeX) experiment and is dedicated to the
observation of both lightning activity and electrical state of continental
and maritime thunderstorms in the area of the Mediterranean Sea. During the
HyMeX SOP1 (Special Observation Period) from 5 September to 6 November 2012,
four European operational lightning locating systems (ATDnet, EUCLID, LINET,
ZEUS) and the HyMeX lightning mapping array network (HyLMA) were used to
locate and characterize the lightning activity over the northwestern
Mediterranean at flash, storm and regional scales. Additional research
instruments like slow antennas, video cameras, microbarometer and microphone
arrays were also operated. All these observations in conjunction with
operational/research ground-based and airborne radars, rain gauges and in
situ microphysical records are aimed at characterizing and understanding
electrically active and highly precipitating events over southeastern France
that often lead to severe flash floods. Simulations performed with cloud
resolving models like Meso-NH and Weather Research and Forecasting are used
to interpret the results and to investigate further the links between
dynamics, microphysics, electrification and lightning occurrence. Herein we
present an overview of the PEACH project and its different instruments.
Examples are discussed to illustrate the comprehensive and unique lightning
data set, from radio frequency to acoustics, collected during the SOP1 for
lightning phenomenology understanding, instrumentation validation, storm
characterization and modeling. |
