Particle distribution inside clouds

In summary, the conversation discusses the need to learn about the distribution of particles within clouds in order to create realistic CG clouds. The speaker mentions finding a program that simulates clouds but requires a map of particle locations, and plans to write a program to create random clouds that are physically accurate. They ask for a description of how particles are located within clouds, starting with the lowest type of clouds. The conversation ends with a suggestion to seek advice from cloud specialists in a specific forum.

Hi,

I need to learn about the distribution of particles within clouds.

I'm looking to create some CGed clouds, and I found a very cool program to simulate them, but it requires I give it a "map" of all particles within each cloud (by location). I'm going to write a program to create random clouds, but I want it to be at least somewhat physically accurate.

So how would you best describe the way the particles that make up clouds are located inside them? I'm well aware that there are many types of clouds, so let's work from the ground up and start with the lowest kind of clouds.

Thanks,
Chen

Hi Chen,

The distribution of particles within clouds can vary depending on the type of cloud and the environmental conditions in which it forms. Generally, particles within clouds are distributed in a non-uniform manner, meaning they are not evenly spread out throughout the cloud. This is due to a variety of factors such as updrafts, downdrafts, and turbulence within the cloud.

In the case of low clouds, such as stratus or cumulus clouds, particles tend to be more evenly distributed near the bottom of the cloud where the air is warmer and more stable. As the cloud extends higher into the atmosphere, the distribution of particles becomes more random and chaotic due to the presence of stronger winds and varying temperatures.

However, in convective clouds like cumulonimbus (thunderstorm) clouds, the distribution of particles can be highly variable and constantly changing due to the strong updrafts and downdrafts within the cloud. This can result in a mixture of larger and smaller particles being present in different areas of the cloud.

Overall, the distribution of particles within clouds is not a simple or uniform process, but rather a complex and dynamic one that is influenced by various factors. I hope this helps in creating a more accurate simulation of clouds in your program. Best of luck!


 

Related to Particle distribution inside clouds

1. What factors affect the distribution of particles inside clouds?

There are several factors that can affect the distribution of particles inside clouds, including the size and density of the particles, air temperature, wind speed, and atmospheric conditions such as humidity and turbulence.

2. How are particles distributed inside clouds?

The distribution of particles inside clouds is determined by a process called Brownian motion, which causes the particles to randomly move and collide with each other. This process leads to a more uniform distribution of particles throughout the cloud.

3. Can particle distribution inside clouds be predicted?

While scientists have developed models and simulations to predict the behavior of particles inside clouds, it is still a complex and unpredictable process. The distribution of particles can also be affected by external factors such as air pollution and natural events like dust storms.

4. What impact does particle distribution inside clouds have on weather patterns?

The distribution of particles inside clouds can affect the formation of precipitation, as well as the intensity and duration of storms. It can also impact the amount of sunlight that is able to penetrate through the cloud, which can affect temperature and weather patterns.

5. How do scientists study particle distribution inside clouds?

Scientists use a variety of methods to study particle distribution inside clouds, including remote sensing techniques, laboratory experiments, and computer simulations. They also collect data through aircraft and satellite measurements to better understand the behavior of particles inside clouds.
