1. SEVERE WEATHER PROJECT

2. Severe Thunderstorms
Thunderstorm produce one or more of the following conditions: high winds, hail, flash floods, and tornadoes.

3. Tornado
Wind moving in 2 directions causes a layer of air in the middle to spin
Spinning column is turned vertical due to strong updrafts
Low central pressure
A funnel cloud forms at the bottom of a cumulonimbus cloud
Once it touches ground it is a tornado
Tornadoes occur in only 1% of all thunderstorms.

4. Hurricanes Large, rotating tropical weather system
Most powerful storms on Earth
Occur at 5-20 degrees latitude N and S
Need warm water to form
Winds spiral in towards intense low-pressure storm center
Categories 1-5

5. Blizzards
Blizzards are severe winter storms that pack a combination of blowing snow and wind resulting in very low visibilities.
While heavy snowfalls and severe cold often accompany blizzards, they are not required.
Sometimes strong winds pick up snow that has already fallen, creating a blizzard.
Officially, the National Weather Service defines a blizzard as large amounts of falling OR blowing snow with winds in excess of 35 mph and visibilities of less than 1/4 of a mile for an extended period of time (greater than 3 hours).

6. Flood
Flooding is when the water level in a creek, river, lake or the sea rises and covers land that is usually dry.
While some floods occur without problem, others are devastating, causing large-scale destruction and significant loss of life.
Flooding is experienced all over the world and in some countries such as Bangladesh, flooding occurs regularly.

7. Wildfire
Any uncontrolled, non-structure fire that occurs in the wilderness.
Wildfires differ from other fires only by their extensive size; the speed at which it spreads out from its original source; its ability to change direction unexpectedly; and to jump gaps, such as roads, rivers and fire breaks.

8. Lightning
An electric discharge that occurs between a positively charged area and a negatively charged area.
Lightning can occur between two clouds, between Earth and a cloud or between two parts of the same cloud.
When lightning strikes, energy is released, which causes air to expand and rapidly send out sound waves (thunder).
