The most important principle underlying the Bergeron process is this:
A)for a given temperature, the saturation vapor pressure of ice is less than that for supercooled water.
B)large drops fall faster than smaller drops.
C)aggregation takes place more rapidly than accretion.
D)the bottom part of the cloud where the process is taking place must be warmer than 0 degrees Celsius.

Question

Quizplus · Accepted Answer

The Bergeron process relies on the fact that for a given temperature, the saturation vapor pressure of ice is less than that for supercooled water. This means that the air in a cloud containing both ice crystals and supercooled water droplets is more saturated with water vapor at the vapor pressure of the ice crystals than it is at the vapor pressure of the supercooled water droplets. As a result, the ice crystals will grow at the expense of the supercooled water droplets, leading to precipitation.
