Document Summary
Weather forecasting tools: the five most important, surface meteorological observations, upper level charts, satellite imagery, computer models, doppler radar. *swaline is where thunderstorms form (visible line of thunderstorm) Thunderstorm: an electrical storm, characterized by lightning and its resulting thunder. It is typically accompanied by heavy rainfall, hail, strong winds, and tornadoes. Ingredients for a thunderstorm: fuel: water vapor, cold air aloft & warm air below: instability, lifting mechanism. Singlecell and multicell squal line: single cell- one updraft and one down draft, multi cell- clusters of thunderstorms, squal line- type of multi cell thunderstorm. Supercell: single cell of mammic proportion, can cover and entire city. Thunder and lightning: a powerful electrostatic discharge produced during a thunderstorm, thunder is the sound created by lightning. 1:2,763,633,600: thunder is the sound lightning makes, light travels faster than sound, warm air less dense than cold air.
