| Descripció: | A thunderstorm that developed over northeastern Spain on 16 June 2006 is analyzed. This
severe thunderstorm produced hailstones as large as 40 mm and had a lifetime of 3 h and
30 min. Radar cross-sections show strong vertical development with cloud echo tops reaching
an altitude of 13 km. The specific characteristics of the lightning activity of this storm were: (i) a
large amount (81%) of negative cloud-to-ground (−CG) flashes with very low peak currents
(b10 kA in absolute value), (ii) a very large proportion of intra-cloud (IC) flashes with an IC/CG
ratio reaching about 400, (iii) a large number of “short” IC flashes (with only 1-VHF source
according to SAFIR detection), (iv) a large increase of the −CG flash rate and of the CG proportion
near the end of the storm. |
