How does StormTracker know where the lightning is?
StormTracker uses a direction-finding antenna to determine the direction the lightning signal came from. StormTracker’s receiver looks at the signal strength to calculate an approximate distance for the lightning strike. There is additional processing done in software to reduce the effect of strike to strike magnitude variations. Once StormTracker knows the direction and distance of the strike it plots it on the map. Recent strike symbols will be shown in a box for 1 minute, at which point it will change to a circle. Negative Cloud to Ground Discharge Negative Intracloud Discharge Positive Cloud to Ground Discharge Positive Intracloud Discharge The old strike (circles) colors go progressively from yellow to red. Yellow being a strike within 10 minutes the next darkest shade between 10-20 minutes and so on.
