When does a Thunderstorm switch from a cumulus stage to a mature stage (what is happening)?
When the updrafts are strong enough to support the development of precipitation
When the downdrafts begin to dominate the storm
When the storm dissipates and loses energy
When the temperature drops significantly
What problem does the terminal velocity of rain have in a thundercloud?
It causes rain to fall too quickly, leading to heavy downpours.
It prevents rain from falling because it is slower than the updrafts
It leads to the formation of hail instead of rain.
It causes rain to evaporate before reaching the ground.
What 2 ways does the air cool in the upper levels of a cumulus cloud?
By radiation and conduction
By evaporation and contact
By adiabatic expansion and mixing with cooler air
By convection and precipitation
What happens to the air as it is cooled?
It expands
It contracts
It remains the same
It becomes lighter
When the downdraft hits the ground, what happens to it?
It dissipates.
It spreads out horizontally.
It intensifies.
It rises back up.
What causes a thunderstorm to “die”?
downdrafts cut off updrafts
Increase in wind speed
Decrease in temperature
all the moisture is lost
How long do thunderstorms last?
Less than 30 minutes
30 minutes to 1 hour
1 to 2 hours
More than 2 hours
What happens to most of the moisture in a thunderstorm?
It evaporates into the atmosphere
It falls as precipitation
It forms clouds
It dissipates without effect
What happens to the upper part of a cumulonimbus cloud in the dissipating stage?
It forms an cirrostratus clouds
It becomes darker.
it begins to spin
It disappears completely.
