Answer to Question 1

Answer: Initial growth through condensation occurs but this is not adequate to produce precipitation. The collision-coalescence process and the Bergeron process operate to grow precipitation size elements. The collision-coalescence process operates through the collision and merging of different size drops in warm clouds where the temperature is above freezing. The Bergeron process occurs in clouds that are below freezing and therefore have a supply of supercooled drops and ice crystals. Riming and aggregation are important agents for achieving precipitation.

Answer to Question 2

Answer: ice storm
