The base altitude of a cumulus cloud depends on the humidity of the lower level of the atmosphere. The more moisture in the atmosphere, the lower the cloudbase.

Meteorologists measure the temperature and dew point of the air (the dew point is the temperature at which water will start to condense out of the air). As the air rises, the temperature of the air will fall at the dry adiabatic lapse rate (approximately 3°C per 1000 ft of altitude) whereas the dew point will fall at 0.5°C per 1000 ft. When the air temperature falls to the local dew point, water will start to condense out of the air and begin to form a cloud. This is the cloudbase.

The altitude of base cumulus clouds can change from day to day due to variations in temperature, humidity, and wind patterns in the atmosphere. These factors can influence the lift and condensation of air, affecting where clouds form and at what altitude they form.

What is the altitude of cumulus clouds?

Cumulus clouds typically form at altitudes between 1,000 to 8,000 meters (3,300 to 26,000 feet) above ground level. The exact altitude can vary depending on factors such as local weather conditions and the time of day.


Cirrus and cumulus are types of what?

Cirrus and cumulus are types of clouds. Cirrus clouds are thin, wispy clouds high in the sky, while cumulus clouds are fluffy, white clouds with a flat base that are found at lower altitudes.


How do you describe a cumulus cloud?

A cumulus cloud is a fluffy, white cloud with a puffy appearance and a flat base. These clouds typically indicate fair weather but can develop into larger storm clouds if conditions change.


What clouds are white with fuzzy edges?

Cumulus clouds are typically white with fuzzy edges. These puffy clouds are often seen on fair weather days and usually appear low in the sky.


What process occurs at the flat base of most cumulus clouds?

At the flat base of most cumulus clouds, warmer air rises and cools as it reaches higher altitudes. This cooling causes water vapor in the air to condense into water droplets, forming the visible cloud.


What are the 3 main types of clouds?

The three main types of clouds are cirrus, stratus, and cumulus. Cirrus clouds are thin and wispy, stratus clouds are low and layered, and cumulus clouds are fluffy and puffy with a flat base.


When can you expect cumulus clouds?

Cumulus clouds typically form during the day when the atmosphere is unstable and warm air rises, causing moisture to condense and form these fluffy clouds. They are commonly seen in fair weather conditions, but can develop into larger storm clouds if the atmosphere becomes more unstable.


How are cumulus clouds and cirrus clouds are alike?

Cumulus and cirrus clouds are both types of atmospheric clouds. They are composed of water droplets and are commonly observed in the sky. However, cumulus clouds are puffy, fluffy clouds with a flat base, while cirrus clouds are wispy, feathery clouds high in the sky.


A massive cloud with rounded sides and a flat base is called?

Cumulus Clouds do.


What are puffy clouds that appear to rise up from a flat bottom?

Those would be cumulus clouds, which are characterized by their fluffy, cotton-like appearance and their flat base. Cumulus clouds often form on fair weather days but can develop into larger storm clouds if conditions are right.


Which clouds form from rising currents of warm air?

Cumulus clouds form from rising currents of warm air. These clouds are typically fluffy and white with a flat base and are associated with fair weather.


What is a Clouds that look like cotton ball called?

Clouds that look like cotton balls are called cumulus clouds. They are puffy, white clouds that often have a flat base and resemble floating cotton balls in the sky.
