Proposal Title: THUNDERSTORM EXPERIMENT
ABSTRACT:
The objectives of the experiment are: 1. To study the link between electrical activity (lightning) and storm
dynamics/microphysics as well as the stage of development of the storm. 2. To determine the dynamics (waves and
turbulence) at the top of and above the cloud,and its evolution according to the storm stage. 3. To determine the
structure of the lightning ashes in the cloud, their location relative to the updrafts/downdrafts and to the
precipitation cores.
