Flashcards in Lesson 304 Evolution Of Precipitation Deck (5):
What are the two processes involved with the formation of precipitation? Describe.
Bergeron effect- water evaporates off a droplet in a cloud deposits on ice crystals in mid to high levels.
Collision process- particles collide creating larger particles
What is the terminology associated with the collision process? Describe.
Coalescence: collision of liquid drops to form larger particles
Aggregation: collision of solid particles to form larger particles
Fragmentation: breaking up of an ice crystal or large water droplet into smaller droplets.
Accretion: collision of solid and liquid particles to form larger particles
Which cloud types are associated with stability? Instability?
Stable: ST, NS, AS, AC, SC (conditionally unstable), CS
Unstable: ACC, TCU, CB, CU,AC, CC.
What type of precipitation falls from Stratiform cloud and cumuliform cloud?
Intermittent or continuous
