The Ultimate Severe Weather Study Guide

A Review of Severe Storms for Tests and Science Competitions

Severe storms are intense storms that occur when the atmosphere is in a disturbed state. Local areas experience destructive weather because of it. While thunderstorms, hailstorms, lightning storms and tornadoes are the first severe weather types we tend to think of, floods and rainstorms, windstorms, and even snowstorms are included in the family of severe weather.

Use this study guide to familiarize yourself with each of these topics including definitions and terminology; severe storm types and development; and some of the worst storms in weather history.

  • How weather radar works and detects precipitation and storms.
  • Look for these shapes, patterns, and colors to find severe storms on radar.
  • Explore weather satellites, including how they work, polar orbiting vs. geostationary, and what satellite images are used in forecasting (visible, infrared, water vapor). 
  • How to read weather maps and interpret weather map symbols.
  • These clouds are typically associated with severe weather.

Thunderstorms & Lightning

  • How rising air (convection) triggers thunderstorms.
  • Thunderstorm basics, including ingredients and life cycle.
  • How hail forms and how big it gets.
  • The 3 main types of lightning and how it forms.
  • Heat lightning vs. ordinary lightning
