RELAMPAGO: Remote sensing of Electrification, Lightning, And 
Meso-scale/micro-scale Processes with Adaptive Ground Observations

Southeastern South America is crossed by the presence of significant 
convective systems that lead to the generation of storms with 
significant rainfall rates and associated severe weather. SALLJEX and 
CHUVA-Santa Maria were two experiments that focused their objectives on 
describe deep convection behavior, but many questions remain unanswered 
and it is necessarily to continue observing one of most active regions 
of the planet.

Some of those questions are:
What controls the diurnal cycle of convective system intensity and 
mesoscale organization on the lee of the Andes?

What are the mesoscale flow features in the region, and how do they 
dictate the triggering of convective systems and the environment for 
storms to grow upscale into MCSs?

What is the role of microphysical and kinematic processes in leading to 
the upscale growth of convective clouds into MCSs?

Does the extreme intensity of the convection in the region impact the 
morphology of the convective systems?

How well do cloud resolving models and regional NWP models represent 
this morphology from case study to seasonal time scales?

Are there inferences of predictability for these processes from 
observations?

How is the influence of the these aerosols on the development of large 
systems?

This is a small list of questions where the scientific community will 
focus during next experiment RELAMPAGO. This experiment will be deployed 
in central Argentina during September - November 2016, covering one of 
the most convective areas on the lee side of the Andes. Local radar 
information, together with the NSF S-Pol, a mobile X-band radar, 
lightening and hail pads observations, a dense precipitation and 
raindrop size distribution observations together with a upper air 
network enhancement will allow to capture microphysics, dynamics and 
thermodynamics characteristics of convective systems over central 
Argentina.
