7. Special Weather Events
There are many types of hazardous weather
Tornadoes
Blizzards
Thunderstorms
Flooding
Hurricanes
Drought

8. Thunderstorms The 3 Key Ingredients of a Thunderstorm MOISTURE
Large bodies of water (warmer temperatures = good)
INSTABILITY
Warm moist air underneath colder dense air
As the warm air rises it will cool and form the CUMULONIMBUS clouds
A LIFTING MECHANISM
Differential heating (Water vs. land), Fronts, Terrain

9. Thunderstorms The 3 Stages of a Thunderstorm TOWERING STAGE
The warm air is forced upwards making the tall fluffy cumulonimbus clouds.
MATURE STAGE
The air that has raised higher cools and the precipitation begins to fall.
DISSIPATION STAGE
The storm runs out of the warm moist air that fuels it.

13. Dissipation Stage

14. Types of Thunderstorms
Ordinary Cell
One cycle through the previous phases
Multi-cell
The storm builds and cycles through several of the phases
Squall Line
The thunderstorm forms a horizontal line that spreads several miles.
Supercell
Last for several hours traveling over long distances. Produce almost all of the significant tornadoes

Tornadoes
Flash-Floods (Greatest cause of death in Thunderstorms)

17. Tornado
A violently rotating column of air descending from a thunderstorm and touching the ground.

18. Formation
Most tornadoes are spawned from supercell thunderstorms. Supercell thunderstorms are characterized by a persistent rotating updraft and form in environments of strong vertical wind shear.
The exact processes for the
formation of a funnel are not
known yet.

21. What’s more dangerous than a tornado?
The Fire Whirl

22. Flooding Basics – Too much water in, not enough water out.
Water “Out” sources – rivers, lakes, INFILTRATION, CSO’s.
Dangers
People underestimate how powerful moving water can be.
Even at low levels moving water is strong.

23. Dangers of moving Water
Of the three deaths which occurred as a result of the Fort Worth tornado, March 28, 2000, one death was due to flooding. The man who drowned was a passenger in a car with his girlfriend, the driver. They approached a low spot with water flowing over the road due to very heavy rain. Flooding was a common occurrence at this location with heavy rains and the danger was well marked.
As the driver drove her car into the water she became frightened as the water rose higher and higher around her vehicle. She backed out to higher ground. The passenger said the water was NOT too deep and he would prove it by walking across to the other side. He never made it.

24. Lake Effect Snow
is produced during cooler atmospheric conditions when COLD winds move across long expanses of WARMER LAKE WATER, providing energy and picking up water vapor which freezes and is deposited on the opposite shores.

26. Students needed more time for the “Most shocking details part!”
It was time consuming.
And more guidance.
