abstract = "The Atmospheric Electricity Group (ELAT) from CCST / INPE had
developed an accurate methodology for cloud-to-ground lightning
warning with one hour in advance for regions with less than 100
km2. Based on real-time total lightning data provided by lightning
detection network, electrostatic field-mill measurements, IR
satellite images, and weather radar images, cloud-to-ground
lightning warnings are issued based on the probability of a
thunderstorm to occur in a particular region. This approach is
very attractive because for specific regions (like airports,
soccer stadiums, oil refineries, mining, parks, etc.), the
forecast based only on numerical models or radar images is not
suitably accurate in time and/or spatial domains. The main purpose
of issuing lightning warnings with some lead time is to protect
human life from lightning threads while in outdoor activities.
Main results are: less than 20% of false alarms, lead time of
about 30 to 40min and warning total duration of about 02 to 03h.
The paper also presents a comprehensive risk analysis of lighting
threads for outdoor activities showing risk maps for different
scenarios as a function of the time of exposure and level of
protection. An example, a lightning warning system that combines
total lightning data and numerical model simulations is also
discussed illustrating how it can predict the occurrence of a
severe storm in a particular region with a lead time of 30 min and
thus help preventing human casualties.",
