  1. Storms

  2. SEVERE WEATHER • Severe weather is any weather that is destructive. • The term is usually used to refer to: • thunderstorms • tornados • tropical storms • snowstorms/blizzards • ice storms • drought

  3. Thunderstorms • Small area storms formed by the strong upwardmovement of warm, moist air • Usually occur ahead of a cold front as the colder, denser air shoves the warmer air upward • This movement of air forms the cumulonimbus clouds that produce thunderstorms • These storms are accompanied by heavy rain, thunder, lightning, sometimes hail, and can also produce tornadoes

  4. All thunderstorms produce lightning • Lightning is the discharge of huge amounts of static electricity (think of walking across a carpet in your socks and then touching something-ZAP) • Thunder is the result of the air quickly expanding from the heat of the lightning bolt • You cannot have lightning without thunder!!

  5. Thunderstorm formations – Form SEVERE storms and tornadoes! THIS IS ONE BIG STORM SYSTEM!

  6. Tornadoes • Form from very powerful thunderstorms (cumulonimbus clouds) • These are funnel shaped columns of spiraling winds that extend down to the ground from the base of a cloud • The winds move into a tornado (low pressure), and can reach a maximum of 318 mph! • Spin COUNTER CLOCKWISE (like a hurricane) • The actual funnel is made by water droplets (clouds) and dust

  7. WINTER STORMS A blizzard is a severe winter condition with low temperatures, strong winds, and heavy blowing snow. An ice storm is a type of winter storm with freezing rain.

  8. DROUGHT A drought is an extended period of months or years when a region receives consistently little or no precipitation.

  9. WILDFIRES are often the result of DROUGHT

  10. A tropical storm is the overall name for a storm which is spinning. They form when warm water heats the air causing it to rise really quickly, then it gets pushed aside as it cools. This pushing causes the clouds to spin. . • Different names for tropical storms: • hurricane • typhoon • severe tropical cyclone • tropical cyclone TROPICAL CYCLONE

  11. Hurricane Katrina Tidal Surge Mississippi Coast

  12. HURRICANES Hurricanes are tropical storms where the winds get faster than 118 km/h (73 mph). The storms have a central area of calm known as the "eye", which is the funnel through which the warm air rises. Why are we seeing more of these destructive storms?
