Most of the precipitation that falls in the middle latitudes is formed by:
A)the Bergeron process.
B)collision-coalescence.
C)spontaneous freezing of water droplets in the absence of condensation nuclei.
D)condensation of water vapor.

Question

Quizplus · Accepted Answer

The Bergeron process is the primary mechanism for precipitation formation in the middle latitudes. It involves the coexistence of supercooled water droplets and ice crystals in a cloud, and the growth of ice crystals at the expense of water droplets, leading to precipitation. Collision-coalescence occurs primarily in tropical regions where there is a lack of ice crystals in the clouds. Spontaneous freezing of water droplets is rare, and condensation of water vapor alone is insufficient to produce precipitation without the presence of condensation nuclei.
