Storms
• A violent disturbance in the atmosphere• Involve sudden changes in air pressure,
which causes rapid air movements• Include
- Thunderstorms- Tornadoes- Hurricanes- Winter storms

Thunderstorms
• A small storm often accompanied by heavy precipitation and frequent thunder and lightning
• Form in large cumulonimbus clouds (thunderheads)
• Can have hail• Can have strong updrafts and downdrafts

Thunderstorms
• Lightning
- positive and negative charges build up in
storm clouds
- an electrical discharge occurs when the charges jump from:
one part of a cloud to another cloud to cloud
cloud to ground

ThunderstormsThunder
• Lightning rapidly heats air
• The rapidly heated air expands suddenly and explosively causing a thunder sound

Thunderstorm
Damage• Flooding/ flash floods• Fires• Unconsciousness, burns, death
Safety• Stay indoors• Avoid electrical conductors• Stay low outdoors• Get out of water

Tornadoes
• A rapidly whirling funnel shaped cloud that reaches Earth’s surface
• Occurs where warm humid air rises rapidly and begins to rotate as it meets other winds

Tornadoes
Damage• From strong wind and flying debris• Ranked on a Fujita scale from 0-5
F0 – light F5 – extreme damageSafety• Move to a shelter, basement, or middle of
ground floor• Stay away from windows Safety video• Lie in a ditch outdoors video

Hurricanes
• Tropical cyclones (low pressure system) with winds over 119 km/hr (74 mph)
• Draw their energy from warm, humid air over water

Hurricanes
Damage
• High waves and flooding
• Wind damage
• Storm surge – dome of ocean water due to low pressure
Safety
• Evacuate

Winter Storms
• Heavy snow and extreme cold
Lake-Effect snow – wind picks up moisture from the warmer Great Lakes. Moisture then precipitates as it is carried over the colder land

Winter Storms
Damage• Blocked roads• Crop damage• Bursts water pipesSafety• Find shelter from wind• Cover exposed body parts• Run car engine if exhaust is clear
