How does ThunderBolt detect lightning?
Lightning is the flow of huge amounts of electrical current within a storm. These currents can range from several thousand amps, all the way up to 250,000 amps. (For comparison, a typical household circuit carries 10-20 amps of current.) The ThunderBolt has a high sensitivity receiver/amplifier that captures a specific frequency in the electromagnetic noise produced by these huge flows of electric current. A microprocessor then analyzes the signals received and determines the distance, along with other important information about the storm activity.
