- •
The adaptation and modification of a lightning jump identification algorithm is presented, based exclusively on the total lightning data.
- •
The lightning jump pattern has proven to be a good forecaster tool.
- •
The technique has been tested with 44 cases of severe weather (hail, tornadoes, and strong winds) in Catalonia.
- •
The lead time between the lightning jump identification and the observation of the severe weather phenomena has been of more or less 20 min in most of the analyzed cases.
