Which are two types of cloud indicate fair weather?
What are the major categories of clouds?
- High-level clouds (5-13 km): cirrocumulus, cirrus, and cirrostratus.
- Mid-level clouds (2-7 km): altocumulus, altostratus, and nimbostratus.
- Low-level clouds (0-2 km): stratus, cumulus, cumulonimbus, and stratocumulus.
What type of cloud can expect fair weather?
The type of cloud that usually signify fair weather is CUMULUS. There are different types of clouds and they can be used as an instrument to predict the type of weather a place is going to experience in a given time. Cumulus cloud has some characteristic properties; they have white puffy appearance, each cloud has a flat base and a rounded top.
What is cloud usually means fair weather?
Cumulus – known as fair-weather clouds because they usually indicate fair, dry conditions. If there is precipitation, it is light. The clouds have a flattish base with rounded stacks or puffs on top.
What is most likely associated with fair weather?
Which of the following is MOST likely associated with fair weather? - a cold front - a warm front - large storm systems - low pressure area - high pressure area
What is the name of the cloud that has rounded tops and flat bottoms?
As the warm air rises and meets cold air, water vapor cools and condenses forming these cotton-like clouds. 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.
What is the name of the cloud that appears as a gray or blueish-gray cloud?
Altostratus clouds are mid-level, flat clouds that appear as gray or blueish-gray clouds expanding across the sky. These clouds are thin enough to allow a distorted image of the sun or moon to peer through. Altostratus tend to form ahead of a warm or occluded front.
What is a cumulus cloud?
Cumulus Clouds: All Is Fair. Tiffany Means. Cumulus clouds are most noticeable for their fluffy white appearance. These low-level clouds typically form on sunny days as the sun heats the ground and warms the air. As the warm air rises and meets cold air, water vapor cools and condenses forming these cotton-like clouds.
What does Cumulonimbus 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.)
How to tell if cirrus is in fair weather?
Because they point in the direction of air movement, you can always tell what direction the wind is blowing at upper levels by simply observing the direction in which the cloud wisps are oriented.
What does it mean when a cloud breaks?
When these clouds begin to break, it is an indication that a cold front is passing. Precipitation Cloud: Yes, steady rain or snow.
What does it mean when you see a cirrus in the sky?
Therefore, if you see a cirrus-filled sky, it's a good indication that weather conditions may soon deteriorate.
How do clouds form?
Clouds form when air cools to the dew point, the temperature at which the air can no longer hold all its water vapour. At this temperature, water vapour condenses to form droplets of liquid water, which we observe as a cloud.
What are Kelvin-Helmholtz clouds?
Kelvin-Helmholtz clouds resemble breaking waves in the ocean. NCAR UCAR OpenSky Repository, CC BY-NC-SA. Kelvin-Helmholtz clouds are rare – the only time I spotted one was over Jutland, western Denmark – because we can only see this process taking place in the atmosphere if the lower air mass contains a cloud.
What is stratus cloud?
Stratus is a low continuous cloud sheet covering the sky. Stratus forms by gently rising air, or by a mild wind bringing moist air over a cold land or sea surface. Stratus cloud is thin, so while conditions may feel gloomy, rain is unlikely, and at most will be a light drizzle.
What happens when a warm front meets a cold front?
In a warm front, a warm and a cold air mass meet. The lighter warm air is forced to rise over the cold air mass, leading to cloud formation. The lowering clouds indicate that the front is drawing near, giving a period of rain in the next 12 hours.
How does the Cumulonimbus work?
Cumulonimbus are often flat-topped. Within the Cumulonimbus, warm air rises by convection. In doing so, it gradually cools until it is the same temperature as the surrounding atmosphere. At this level, the air is no longer buoyant so cannot rise further. Instead it spreads out, forming a characteristic anvil shape.
What does a sunny day look like?
This warmed air rises by convection and forms Cumulus. These “fair weather” clouds look like cotton wool . If you look at a sky filled with cumulus, you may notice they have flat bases, which all lie at the same level.
Does cirrus produce rain?
Only at very high altitudes or latitudes do Cirrus produce rain at ground level. But if you notice that Cirrus begins to cover more of the sky, and gets lower and thicker, this is a good indication that a warm front is approaching. In a warm front, a warm and a cold air mass meet.
What cloud can produce heavy rain?
If enough atmospheric instability, moisture, and lift are present, then strong updrafts can develop in the cumulus cloud leading to a mature, deep cumulonimbus cloud, i.e., a thunderstorm producing heavy rain.
How are clouds classified?
Clouds are classified according to their height above and appearance (texture) from the ground. The following cloud roots and translations summarize the components of this classification system: 1) Cirro-: curl of hair, high. 3) Strato -: layer. 5) Cumulo-: heap.
What is a stratocumulus cloud?
Stratocumulus clouds are hybrids of layered stratus and cellular cumulus, i.e. , individual cloud elements, characteristic of cumulo type clouds, clumped together in a continuous distribution, characteristic of strato type clouds. Stratocumulus also can be thought of as a layer of cloud clumps with thick and thin areas.
What is a Cirrostratus cloud?
They often are the first sign of an approaching warm front or upper-level jet streak. Unlike cirrus, cirrostratus clouds form more of a widespread, veil-like layer (similar to what stratus clouds do in low levels).
What is a narrow, elongated cloud formed as jet aircraft exhaust condenses in cold air at high
Contrail: Narrow, elongated cloud formed as jet aircraft exhaust condenses in cold air at high altitudes, indicative of upper level humidity and wind drift. Contrails Contrails in the sky from jets. Fog: Layer of stratus clouds on or near the ground.
What type of cloud is Altostratus?
Altostratus clouds are "strato" type clouds (see below) that possess a flat and uniform type texture in the mid levels. They frequently indicate the approach of a warm front and may thicken and lower into stratus, then nimbostratus resulting in rain or snow.
What are the two types of low clouds?
The two main types of low clouds include stratus, which develop horizontally, and cumulus, which develop vertically. Stratus clouds are uniform and flat, producing a gray layer of cloud cover which may be precipitation-free or may cause periods of light precipitation or drizzle.

Answer
The two types of clouds that indicate fair weather are cirrus and cumulus. Cirrus is a type of clouds that is compared and nicknamed sometimes as the hairs of an angel because it is so thin. Unlike cirrus that appears at high altitudes, cumulus generally are formed closer to the earth surface.

What is the weather called when clouds are overcast?
7. some of the most extreme weather, including heavy rain, hail, snow, thunderstorms, tornadoes and hurricanes. Stratus – dull greyish clouds that stretch across and block the sky. They look like fog in the sky. Stratus cover is also called overcast. If their bases reach the ground, they become fog.
What are the different types of clouds?
Different clouds mean different types of weather. Cloud names that describe the shapes of clouds are: cirrus – meaning curl (as in a lock of hair) or fringe. cumulus – meaning heap or pile. stratus – meaning spread over an area or layer. Nimbus means rain-bearing, and alto means high.

What is the name of the cloud that turns into a hurricane?
Cirrocumulus – like ripples or fish scales (sometimes called a mackerel sky). When cirrus clouds turn into cirrocumulus, a storm may come – in tropical regions, that could be a hurricane. Cirrostratus – like thin sheets that spread across the sky and give the sky a pale, whitish, translucent. 5. appearance.
What is a cirrus cloud?
Cirrus clouds – thin, wispy clouds strewn across the sky in high winds. A few cirrus clouds may indicate fair weather, but increasing cover indicates a change of weather (an approaching warm front. 4. ) will occur within 24 hours. These are the most abundant of all high-level clouds.
What are clouds made of?
They are mostly made of water droplets but can contain ice crystals. The clouds are often seen as bluish-grey sheets that cover most, if not all, of the sky. They can obscure the Sun. Altocumulus – composed of water droplets and appear as layers of grey, puffy, round, small clouds.
