WebNo one is sure why lightning bolts follow a zigzag path as they move. The main bolt or stroke will go back up to the cloud. It will make a flash of lightning. It will also heat the air. The air will spread quickly. It will make the sound we hear as thunder. Be Safe in a Storm Lightning is dangerous. Here are some safety rules. WebThe lightning channel, along which the return-stroke current propagates from the ground upwards, is assumed to be rectilinear and vertical, with a finite length H. As illustrated in Fig. 1 , a Cartesian orthogonal coordinate system is chosen in such a way that its z -axis and its origin O coincide with the lightning channel and its base ...

Lightning Mechanism of Lightning Discharge Leader Streamer

WebThe return stroke is the very bright visible flash that we see as lightning, caused by the rapid discharge of electricity. Once the step leader makes contact with a streamer, the negative charge that has accumulated along the leader channel flows rapidly to ground. The … Figure 2 shows the various components of a lightning flash including the stepped … Lightning is one of the top three storm-related killers in the United States. It is als… WebStroke Definition A stroke is the sudden death of brain cells in a localized area due to inadequate blood flow.

Transient Luminous Events and Their Relationship to Lightning Strokes …

WebMost commonly, the lightning current ceases in about a millisecond for a given stroke, but sometimes there is a continuing current on the order of 100 amps following one or more of the strokes. This is called "hot lightning" and it is the cause of lightning fires according to Uman. The temperatures of lightning are 15,000-60,000°F for both ... WebLightning is a discharge of electricity. A single stroke of lightning can heat the air around it to 30,000°C (54,000°F)! This extreme heating causes the air to expand explosively fast. The expansion creates a shock wave that turns into a booming sound wave, known as thunder. What's Happening Within the Cloud? WebThese two systems work by detecting radio waves (sferics) emitted by fast electric currents (strokes) in lightning channels. A “stroke” can be a fast current within the cloud, or a “return stroke” in a channel to ground. CG return strokes usually have larger currents that make stronger signals that are easier to detect. the science and engineering of cutting
