  1. Lightning location and Application Laboratory

  2. Accessing lightning data • LIS and STARNET

  3. LIS • Access • http://thunder.msfc.nasa.gov/cgi-bin/LISSearch.pl?type=HTML?

  4. Select the Position

  5. Select the area and period – Maximum 12 months

  6. Click to download the data

  8. Data link

  9. Use of Field Mill • Understanding the Thunderstorm structure • Thunderstorm approximation and • Lightning activity

  10. Santa Maria - Campaign

  11. 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.

  12. Lightning signatures in Radars • Cross-Sections Examples: Argentina – 18 November of 2009 São Paulo – 12 March of 2012

  13. 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 Paulocd Desktop/TNOTE-Rayos/CTH_LMA

  14. 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.
