Answer to Question 1
Answer: Collision-coalescence: As it falls, a collector drop collides with some of the droplets in its path and overtakes some of the smaller droplets in its path, growing larger in the process. Bergeron: The principle underlying the Bergeron process is that the saturation vapor pressure over ice (the amount of water vapor needed to keep it in equilibrium) is less than that over supercooled water at the same temperature. Evaporation from supercooled droplets increases the water vapor content of the air, which causes further deposition onto the ice crystals.
