The mature stage of a thunderstorm begins with
A
formation of the anvil top.
B
the start of precipitation.✓ Correct Answer
C
continuous downdrafts.
Explanation
A thunderstorm cell goes through cumulus, mature and dissipating stages. According to PHAK Ch. 12, precipitation beginning to fall from the cloud base signals that a downdraft has developed and the cell has entered the mature stage. The anvil top forms later as the storm reaches maturity, and continuous downdrafts throughout the cell characterize the dissipating stage.
