What are the processes that happen in the Bergeron process?

The Wegener–Bergeron–Findeisen process (after Alfred Wegener, Tor Bergeron and Walter Findeisen), (or “cold-rain process”) is a process of ice crystal growth that occurs in mixed phase clouds (containing a mixture of supercooled water and ice) in regions where the ambient vapor pressure falls between the saturation …

What are the six types of precipitation?

The different types of precipitation are:

Rain. Most commonly observed, drops larger than drizzle (0.02 inch / 0.5 mm or more) are considered rain.
Drizzle. Fairly uniform precipitation composed exclusively of fine drops very close together.
Ice Pellets (Sleet)
Hail.
Small Hail (Snow Pellets)
Snow.
Snow Grains.
Ice Crystals.

Which sequence best describes thunder formation?

Which sequence best describes thunder formation? counterclockwise; north and northeast.

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 main difference between collision coalescence and the Bergeron process?

Unlike the Bergeron Process, where precipitation forms under supercooled conditions, the Collision and Coalescence Process typically occurs within relatively warm clouds with tops warmer than -15C.

What are the two processes of precipitation?

Precipitation processes Two of the main theories accepted as being principally responsible for the formation of the precipitation particles are the Collision-coalescence process and the Bergeron/ ice crystal process.

Which is a description of the Bergeron process?

The Bergeron process can be summarized as such: The air reaches saturation and some of the resulting droplets will come in contact with freezing nuclei (assuming they have reached the activation temperature). We will now have a combination of ice crystals and supercooled water droplets.

What does Bergeron-Findeisen process of precipitation mean?

(Commonly called the ice process of precipitation, and formerly, ice- crystal theory; also Bergeron–Findeisen–Wegener process or theory, and with the names in a different order.) A theoretical explanation of the process by which precipitationparticles may form within a mixed cloud(composed of both ice crystalsand liquid water drops).

What happens to ice crystals in the Bergeron process?

It may even collide with other ice crystals and grow larger still through collision coalescence, aggregation, or accretion. The Bergeron process often results in precipitation. As the crystals grow and fall, they pass through the base of the cloud, which may be above freezing. This causes the crystals to melt and fall as rain.

What makes supercooled droplets freeze in the Bergeron process?

4. The Bergeron Process• Additionally, supercooled droplets will freeze on contact with solid particles that have a crystal form closely resembling ice (like silver oxide- the chemical compound used in cloud seeding).• These types of materials are referred to as frozen nuclei.•
