| Zusammenfassung |
| Thunderstorms and their ground effects, such as flash floods, hail,
lightning, strong winds, and tornadoes, are responsible for most weather
damages in northern Italy, especially in the warm season from May to
September. A nowcasting and warning system focused on severe thunderstorm
events would be useful to reduce risks for people involved in outside
activities and for electric, telecommunication, and sensitive industrial
business. C-band radar and Lighting Location Systems provide useful, fast
and high resolution data for the detection of convective systems and for
following their dynamics. The whole of northern Italy is covered by radar
with a resolution of 1 km and by a lightning network with a mean accuracy of
0.5 km on the single point of impact. The authors present an algorithm
developed for tracking high intensity storm cells by means of radar and
lightning data. Application to northern Italy reveals that tracking
thunderstorm cells can be used as an alert system that may help prevent
damages from extreme weather, as well as allowing for studying the
correlation among lightning, rainfall and tornado occurrence. Assessing the
algorithm skill is also discussed, and a forecast verification method is
described and applied for the duration of a thunderstorm season. |
