What happens during the cumulus stage of a thunderstorm?

• The storm begins to break up
• The storm creates lightning thunder and heavy rain
• The cool air rises and stratus clouds build
• The warm air rises and cumulus clouds build

What happens during the mature stage of a thunderstorm?

• The storm begins to break up
• The storm creates lightning thunder and heavy rain
• The cool air rises and stratus clouds build
• The warm air rises and cumulus clouds build

What happens during the dissipating stage of a thunderstorm?

• The storm begins to break up
• The storm creates lightning thunder and heavy rain
• The cool air rises and stratus clouds build
• The warm air rises and cumulus clouds build

What is the best reason to stay away from metal objects during a thunderstorm?

__________________________ fuel a thundertorm with warm, moist air.

• Updrafts

• Winds

• Clouds

• Heat waves

Very strong localized downdrafts (gusts of wind) can create sudden

• microbursts

• downbursts

• thunderstorm cells

• lightning

The smallest, most intense downbursts can produce winds approaching 270 km/hr (170 miles/hr)

• microbursts

• downbursts

• thunderstorm cells

• lightning

Downdrafts begin to prevent warm moist air from rising and cut off the thunderstorm's power supply.

• Cumulus Stage

• Mature Stage

• Dissipating Stage

• Return Stroke

Super cells usually occur during

• spring and early summer

• fall and early winter

• winter and early summer

• summer and early fall
