thunder and lightning?
Lightning is an abrupt electric discharge from cloud to cloud or from cloud to earth accompanied by the emission of light. Lightning is produced to balance the differences between positive and negative charges within a cloud, between two clouds, or between the cloud and the ground. . Thunder is a booming or crashing noise caused by air expanding along the path of a bolt of lightning. Without lightning, there would be no "thunder" in "thunderstorm." Thunder is the noise lightning makes as it travels through the air. Lightning occurs during all thunderstorms (though not every time it rains).Lightning forms when updrafts of air carry water droplets, which have a charge, upward to heights where some freeze into ice and snow particles. They form a cloud. As these particles begin to fall back to Earth, charges within the cloud become mixed. The differences in charge are released as lightning. You'll normally hear the sound of lightning a few moments after you see the sky light up. Light travels faster than sound, so if you are at a distance from the storm, lightning and thunder may seem oddly disconnected.Lightning is five times hotter than the sun. A single bolt can reach 50,000 degrees Fahrenheit.
There are essentially four types of thunderstorms: single cell storms which last about 20-30 minutes. Pulse storms can produce severe weather elements such as downbursts, hail, some heavy rainfall and occasionally weak tornadoes. Multicell cluster storms are a group of cells moving as a single unit, with each cell in a different stage of the thunderstorm life cycle. Multicell storms can produce moderate size hail, flash floods and weak tornadoes. Multicell line storms consist of a line of storms with a continuous, well developed gust front at the leading edge of the line. Also known as squall lines, these storms can produce small to moderate size hail, occasional flash floods and weak tornadoes. Supercells are thunderstorm swith a rotating updraft, these storms can produce strong downbursts, large hail, occasional flash floods and weak to violent tornadoes.
