The microphysics of the warm-rain and ice crystal processes of
网页2023年6月27日 · Precipitation in clouds can form by either warm-rain or ice crystal processes, referred to as warm and cold formation pathways, respectively. Here, we investigate the warm and cold pathway...
Cloud physics - Wikipedia
网页Cloud physics is the study of the physical processes that lead to the formation, growth and precipitation of atmospheric clouds. These aerosols are found in the troposphere, stratosphere, and mesosphere, which collectively make up the greatest part of the homosphere. Clouds consist of microscopic droplets of liquid water (warm clouds), tiny ...
Chapter 7: Precipitation Processes – Atmospheric Processes and …
网页Which rain formation process produces most of the worlds precipitation? What type of cloud does this process occur in? What factors determine how large a cloud droplet can grow through collision-coalescence? Match the ice nucleation methods:
Precipitation Growth in Cold Clouds - Warm versus Cold Clouds
网页Cold Clouds. Cold clouds are defined as those clouds with tops colder than 0°C. can be comprised of: water; super-cooled water - liquid droplets observed at temps less than 0°C; ice; Notice that super cooled water is found at altitudes where:
Clouds and Precipitation - SpringerLink
网页2020年11月6日 · Frontal precipitation usually occurs when a warm front encounters a cold front. The less dense warm air parcel rises and cools into the ascedental flow in region of strong updrafts. The heavier cold sinks at the near surface and form clouds.
Precipitation (Chapter 9) - An Introduction to Clouds
网页2016年6月5日 · We discuss how estimates of precipitation rates can be obtained from radar measurements and how radar images can be interpreted (Section 9.3). Next we discuss how precipitation can be classified into stratiform and convective precipitation (Section 9.4) and explain its mesoscale structure (Section 9.5).
ACP - Cold cloud microphysical process rates in a global …
网页2021年2月4日 · This study quantifies and investigates the ICNC rates of cold cloud microphysical processes by means of the chemistry–climate model EMAC (ECHAM/MESSy Atmospheric Chemistry) and defines the hierarchy of sources and sinks of ice crystals.
The cooling of light rains in a warming world - Nature
网页2021年6月3日 · Warm clouds produce ‘warm rain’ — lighter rainfall derived from liquid water processes — and are less efficient at precipitation, so they have a longer atmospheric lifetime relative to ...
Cold clouds (Chapter 12) - Physics and Chemistry of Clouds
网页Early in the history of cloud physics, ice formation was thought to be a prerequisite for precipitation in all clouds, but we now realize that the warm-cloud processes of condensation and collision-coalescence are sufficient to produce rain in some clouds (e.g., tropical maritime cumuli), and they can coexist with, even augment, the cold-cloud p...
Atmosphere - Precipitation, Water Cycle, Air Pressure
网页2024年8月22日 · A cloud that contains ice crystals is referred to as a cold cloud, and the resulting precipitation is said to be the product of cold-cloud processes. Traditionally, this process has also been referred to as the Bergeron-Findeisen mechanism, for Swedish meteorologists Tor Bergeron and Walter Findeisen , who introduced it in the 1930s.
