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 .
Cloud seeding can be done by ground generators or planes [citation needed] This image explaining cloud seeding shows a substance – either silver iodide or dry ice – being dumped onto the cloud, which then becomes a rain shower. The process shown in the upper-right is what is happening in the cloud and the process of condensation upon the ...
Since the 1940s, cloud seeding has been used to change the structure of clouds by dispersing substances into the air, potentially increasing or altering rainfall. [2] In spite of experiments dating back to at least the start of the 20th century, however, there is much controversy surrounding the efficacy of cloud seeding, and evidence that cloud seeding leads to increased precipitation on the ...
Cloud seeding can be done by ground generators (left) or planes. Cloud seeding is a common technique to enhance precipitation. Cloud seeding entails spraying small particles, such as silver iodide, onto clouds to attempt to affect their development, usually with the goal of increasing precipitation. Cloud seeding only works to the extent that ...
The type of precipitation will depend on the temperature structure in the cloud and below it: In winter, when the temperature in the cloud is below freezing (0 °C), snowflakes will be generated: They will melt and give raindrops if the temperature rises above it in a deep layer between the cloud and the ground.
And rain occurs when it's "warm" all the way from the clouds to the surface. But it's freezing rain and sleet that are getting quite a bit of attention this week as an icy winter storm takes aim ...
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls from clouds due to gravitational pull. [1] The main forms of precipitation include drizzle, rain, Rain and snow mixed ("sleet" in Commonwealth usage), snow, ice pellets, graupel and hail.
Convective precipitation falls over a certain area for a relatively short time, as convective clouds have limited vertical and horizontal extent and do not conserve much water. Most precipitation in the tropics appears to be convective; however, it has been suggested that stratiform and convective precipitation often both occur within the same ...
