Workshop on Coupling of Thunderstorms and Lightning Discharges to Near-Earth Space
23-27 June 2008, University of Corsica, Corte, France
|Discovered in the early 1990s, sprites, jets and elves, also referred to as
“Transient Luminous Events (TLEs)” are flashes of optical emissions in the stratosphere
and mesosphere above severe thunderstorms. These “fireworks” include Earth’s largest
electrical discharges reaching from the top of thunderclouds to the bottom ionosphere
at 80 km altitude. Also during the 1990s, bursts of X- and gamma-rays were observed by
spacecraft, from the atmosphere above thunderstorms. These so-called “Terrestrial Gamma-ray
Flashes” (TGFs) are thought to be bremsstrahlung radiation from relativistic electrons
accelerated in the electric fields above thunderstorms. TLEs and TGFs are newly discovered
processes that couple the troposphere to the upper atmosphere and near-Earth space.
The proposed workshop aims to better
understand and identify the various physical processes that couple thunderstorms to the Earth’s
upper atmosphere and ionosphere, and the effects of thunderstorm processes on the atmospheric
composition and dynamics. The workshop will consist of invited tutorials and contributed talks, and an
interactive poster session. There will also be organized splinter meetings targeted at
the different communities (ASIM, TARANIS, E-CANES, etc.) and ample time for discussing current
projects and future collaborations. The workshop will cover observations, simulations, theory
and instrument technical aspects related to the following topics:
- TLEs and TGFs
- Response of the Atmosphere to TLEs
- Electrification in Severe Storms
- Troposphere-Stratosphere Transport by Tropical Convective Storms
- Gravity Waves Generated by Thunderstorms
- Lightning-Induced Electron Precipitation (LEP) Events
- Lightning Effects on Mesospheric Airglow
- The Global Atmospheric Electric Circuit
- Current and Future dedicated Missions, associated measurements and modelling
- Instrumental Techniques
Post Workshop Information:
| The workshop is partly sponsored by The European Space Agency,
Human Spaceflight and Exploration Directorate, Topical
Team on the Atmosphere-Space Interaction Monitor (ASIM),
the French National Space Agency (CNES) in the context of the TARANIS (Tool for the Analysis of RAdiations
from lightNIngs and Sprites) mission,
the French National Center for Scientific Research (CNRS) European
research network (GDRE) entitled "Electromagnetic Coupling of the
Atmosphere with near-Earth Space (E-CANES)"
and also by COST Action P18 "The Physics of Lightning Flash and Its
Effects". The US National Science Foundation (NSF) Aeronomy program (Director Cassandra Fesen) and Physical
and Dynamical Meteorology Program (Director Brad Smull) is also partly sponsoring the workshop.
