How does the Bergeron process work?
In the Bergeron process, ice crystals grow as water vapor deposits onto the crystal, while the supercooled liquid water droplets evaporate. This occurs because the saturation vapor pressure for water is higher than the the saturation vapor pressure for ice.
What does the Bergeron process explain quizlet?
Bergeron Process. A process that produces percipitation; the process involves tiny ice crystals in a supercooled cloud growing larger at the expense of the surrounding liquid droplets. vapor pressure. Pressure exerted by water vapor on the surroundings. relative humidity.
Is hail created through the Bergeron process?
The Bergeron process is a mechanism that causes the formation of precipitations of many hydrometeors (rain, snow, hail, etc.). In the area under the freezing point of a cloud, water exists in its three phases: gaseous (vapour), liquid (supercooled) and solid (ice crystal).
What is collision coalescence process?
The collision-coalescence process is exactly as it sounds: cloud droplets collide and coalesce or stick together. This advantage allows them to fall faster and collide with smaller cloud droplets. Sometimes the cloud droplets will stick together and coalesce to form a larger droplet.
What is the Bergeron process in simple terms?
The process by which precipitation is initiated in a mixed cloud with a temperature below freezing. Because the equilibrium vapour pressure of water vapour with respect to ice is less than that with respect to liquid water, ice crystals grow at the expense of supercooled water droplets.
Why is the Bergeron process important?
The Bergeron process is most important in clouds with temperatures below freezing. It involves interactions between ice particles, supercooled water, and water vapor – hence the name “three-phase process”). Collision is self-explanatory. Liquid cloud droplets carried by air motions within a cloud can collide.
What process explains the formation of raindrops in warm clouds?
raindrops form as the result of repeated collisions between cloud droplets. In warm clouds, droplets can grow and form precipitation by condensation in a supersaturated environment and by colliding and coalescing with other cloud droplets.

Why can’t Bergeron processes take place in warm clouds?
Thus, a saturation pressure gradient exists between the ice crystal and the supercooled water. grows rapidly into a crystal capable of precipitating. Why can’t the Bergeron process take place in warm clouds? They act as a source of water vapor integral to cloud and precipitation development.
What is the rainmaking process called?
artificial precipitation
Rainmaking, also known as artificial precipitation, artificial rainfall and pluviculture, is the act of attempting to artificially induce or increase precipitation, usually to stave off drought or the wider global warming.
Why do raindrops fall?
Gravity pulls everything downward. As an object falls, it experiences a frictional drag that counters the downward force of gravity. As the raindrops fall they are flattened and shaped like a hamburger bun by the drag forces of the air they are falling through.
Why is the Bergeron Findeisen process so important?
The result is an area surrounding the cirrus clouds that is free of cloud droplets. The Bergeron‐Findeisen process is a primary mechanism for precipitation. Although there are many other cloud processes that are also responsible for precipitation, this process plays an important part in the growth of ice crystals.
Who is the founder of the Bergeron theory?
Bergeron theory (Bergeron—Findeisen theory) A theory, proposed around 1930 by T. Bergeron, and subsequently developed by W. Findeisen, that provides a mechanism for the growth of raindrops in ice/water cloud.
How did Wegener come up with the Findeisen process?
Wegener theorized that if this process happened in clouds and the crystals grew large enough to fall out, that it could be a viable precipitation mechanism. While his work with ice crystal growth attracted some attention, it would take another 10 years before its application to precipitation would be recognized.
How did Bergeron come up with the hoarfrost theory?
In 1911, Wegener theorized that the process which creates hoarfrost, if it also occurs in clouds, could be a mechanism for precipitation if the crystals grow sufficiently large to fall out. Bergeron, who is most closely associated with the process, presented his theory in 1933 in support of Wegener.
