Presentation Transcript

  1. Thunderstorms

  2. Cumulus Stage • Growth stage • Warm, humid air rises then cools and condenses. • Top of cloud evaporates and makes the air more humid. This allows the cloud to grow taller. • No lightning, thunder or precipitation

  3. Cumulus Stage

  4. Mature Stage • Downdraft – cooler air is heavier and begins to sink. • Downdraft and updraft of mature thunderstorm are called the “cell” • Most intense stage • Has lightning, thunder, heavy rain, hail

  5. Mature Stage

  6. Dissipating Stage • Downdraft overpowers the updraft. This cuts off the storms supply of warm, moist air. • Lower level cloud evaporates quickly. • All three stages can happen in less than an hour

  7. Dissipating Thunderstorm

  8. SupercellThunderstorm • Horizontal spin is tilted into updraft and causes the storm to rotate. • Often lasts longer, is larger and much more severe. • Good chance for a tornado
