When would you see a cumulus cloud?
These are the awe-inspiring and ominous clouds mainly observed during the summer months and can be indicative of developing thunderstorms, including lightning, hail, heavy rain and even tornadoes. The strongest thunderstorms can even produce cumulonimbus clouds that tower up to 60,000 feet!
What is the temperature of a cumulus cloud?
As cumulus clouds grow higher, their tops become colder. Eventually, when a temperature of about -10°C is reached, the water droplets of the cloud (which are by then supercooled) begin to freeze and become ice crystals. The anvils of cumulonimbus clouds are composed predominantly of ice crystals.
Are cumulus clouds fair weather?
Cumulus humilis are cumuliform clouds with little vertical extent, common in the summer, that are often referred to as “fair weather cumulus”. These clouds may later metamorphose into cumulus clouds when convection is intense enough, though the presence of these types of clouds usually indicates fair weather.
What facts describe cumulus clouds?
Cumulus clouds are puffy clouds that sometimes look like pieces of floating cotton. The base of each cloud is often flat and may be only 1000 meters (3300 feet) above the ground. These clouds grow upward, and they can develop into a giant cumulonimbus, which is a thunderstorm cloud.

Do altostratus clouds rain?
Altostratus clouds are “strato” type clouds (see below) that possess a flat and uniform type texture in the mid levels. However, altostratus clouds themselves do not produce significant precipitation at the surface, although sprinkles or occasionally light showers may occur from a thick alto- stratus deck.
What is the color of cumulus?
Fair weather cumulus have the appearance of floating cotton with a flat base and distinct outlines, and colors range from white to light gray. Fair weather cumulus have a lifetime of anywhere from 5-40 minutes and show only slight vertical growth, with the tops designating the limit of the rising air.
Is BM cumulus cloud warm or cool?

What is the lifespan of a cloud?
The average lifespan of a cumulus cloud is less than one hour, after which it either turns to a cumulonimbus cloud or tends to disintegrate.
How are cumulus clouds used to predict the weather?
Cumulus clouds commonly have rounded tops and flat darker bottoms. Those with little vertical development indicate that the weather will be fair. Cumulus clouds can also grow vertically forming cumulonimbus clouds. These clouds indicate heavy rain and severe weather.
What kind of clouds look like cumulus clouds?
Cumulus clouds are detached, individual, cauliflower-shaped clouds usually spotted in fair weather conditions. The tops of these clouds are mostly brilliant white tufts when lit by the Sun, although their base is usually relatively dark.
What does a cumulonimbus cloud in the sky mean?
Just like you see a cumulus cloud and know it means fair weather, cumulonimbus mean the weather is stormy. (Ironically, it is the very act of these harmless fair weather cumulus clouds overdeveloping that creates cumulonimbus.)
When do cumulus clouds form over the sea?
Along coastlines, cumulus may form over land during daylight hours as a sea breeze brings in moist air, which is then warmed by the surface. This effect reverses overnight as the sea becomes warmer than the land and cumulus form over the sea. What weather is associated with cumulus clouds?
