Use of Field Mill
• Understanding the Thunderstorm structure
• Thunderstorm approximation and
• Lightning activity
Santa Maria - Campaign
Lets simulate the Ez
• cd Desktop/TNOTE-Rayos• cd E-Field• ./profiler_lin64• You can edit the file parametros.dat to modify the position of the charge centers and check
how Ez changes with distance• Try to see if you can find a configuration that resembles
the previous image.• This exercise will provide a hint to interpret electrical field
measurements, because it will be possible to know if a thunderstorm is approaching and if it is severe or not.
Lightning signatures in Radars
• Cross-Sections
Examples:
Argentina – 18 November of 2009
São Paulo – 12 March of 2012
Play with the cross sections
• Mainly try to find differences in the radar reflectivity profiles with and without lightning.
Run ./profiler_lin64
Argentina cd Desktop/TNOTE-Rayos/Radar_STARNET
São Paulo
cd Desktop/TNOTE-Rayos/CTH_LMA
• Try to go to the storms and make cross sections where you have lightning and not.
• Compare the cross section to find signatures on Z (value and height) that is associated with Lightning activity.
• This will help you to forecast if a lightning is possible and depending on the signature you might even have hail.
