How does the Stratus cloud form?
Stratus clouds form when a sheet of warm, moist air lifts off the ground and depressurizes, following the lapse rate. This causes the relative humidity to increase due to the adiabatic cooling.
What is the 4 types of clouds?
The Four Core Types of Clouds Cirro-form. The Latin word ‘cirro’ means curl of hair. Cumulo-form. Generally detached clouds, they look like white fluffy cotton balls. Strato-form. From the Latin word for ‘layer’ these clouds are usually broad and fairly wide spread appearing like a blanket. Nimbo-form.
What is an example of a stratus cloud?
Mid-level (about 2-8 km), stable cloud layer. Indicative of widespread stable ascent. Fall streaks (virga) are possible but precipitation rarely reaches the ground. Altostratus consists of supercooled droplets or ice crystals.
What is the shape of a stratus cloud?
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.
Where are stratus clouds found?
Stratus clouds are the lowest type found in the troposphere; they are often found at ground level as fog or mist.4 days ago.
How do you draw sky and clouds?
Let’s get started! Step 1: Lightly draw a simple outline of a cloud. Step 2: Shade the sky—not the cloud! Step 3: Blend your layers until smooth. Step 4: Gently add shape to your cloud. Step 5: Increase your contrast. Step 6: Finish up with small details. 9 Coloured Pencil Drawing Tips for Beginners.
What do nimbus clouds do?
A nimbostratus cloud is a multi-level, amorphous, nearly uniform and often dark grey cloud that usually produces continuous rain, snow or sleet but no lightning or thunder. Nimbostratus usually produces precipitation over a wide area. Nimbo- is from the Latin word nimbus, which denotes cloud or halo.
What are clouds for kids?
A cloud is made up of liquid water droplets. A cloud forms when air is heated by the sun. As it rises, it slowly cools it reaches the saturation point and water condenses, forming a cloud. As long as the cloud and the air that its made of is warmer than the outside air around it, it floats!.
What does a GREY cloud mean?
Most clouds are white, but rain clouds are usually a darker shade of gray. They are gray because of their thickness or height. Basically, clouds look gray when they block out sunlight. A cloud gets thicker as it gathers more water droplets and ice crystals. The thicker a cloud gets, the less light can pass through it.
What are the 3 types of stratus clouds?
Stratus Cloud Varieties Stratus clouds have three associated cloud varieties: opacus, translucidus, and undulatus.
Is fog a stratus cloud?
Stratus is used to describe flat, featureless clouds of low altitude, typically less than 300 metres. On the other hand, fog is a stratus cloud in contact with the ground. Horizontal visibility in fog is less than 1 km.
How long is a stratus cloud?
Storm and Cloud Dynamics The lifetimes of stratus and stratocumulus clouds are longer, ranging from 6 to 12 h. As in fog, the time scale for a parcel to enter a stratus having a mean vertical velocity of 0.1 m s−1 and rising through a depth of, say, 1000 m may be 3 h.
How far off the ground is a stratus cloud?
Found at very low levels (less than 2000 meters, or 6500 feet), stratus clouds are thick, large, heavy-looking gray clouds that dominate the sky. Precipitation normally does not occur with this cloud, although drizzle or mist may be observed.
What altitude do stratus clouds form?
Stratus. Usually forms between the surface and 2,000ft, but cloud base can be up to 4,000ft. Thick stratus can produce considerable precipitation, particularly in hilly or coastal regions, though in some cases this precipitation may be falling from higher clouds such as nimbostratus.
What do stratus clouds predict?
These clouds can forecast 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.
What color are stratus clouds?
Stratus clouds are low-level layers with a fairly uniform grey or white colour. Often the scene of dull, overcast days in its ‘nebulosus’ form, they can persist for long periods of time. They are the lowest-lying cloud type and sometimes appear at the surface in the form of mist or fog.
What are some fun facts about stratus clouds?
Here are some interesting facts about stratus clouds: Stratus clouds have flat layers and uniform bases, with no visible clumps or lumps. They produce light precipitation in terms of drizzle and snow. They accompany foggy weather conditions. Stratus clouds can last for about 6 to 12 hours in the atmosphere.
What is the meaning of stratus clouds?
Definition of stratus : a low cloud form extending over a large area at altitudes of usually 2000 to 7000 feet (600 to 2100 meters) — see cloud illustration.
How do you draw color clouds?
How to Draw Clouds with Colored Pencil Step 1: Lightly outline the clouds and land and shade the sky. Step 2: Lift a few more clouds with mounting putty. Step 3: Blend with odorless mineral spirits or other art solvent. Step 4: Continue layering and blending until the blue sky is finished.
How do you make a cloud color?
Mix a lighter white to put next to the ‘darker’ white of your cloud as seen in the images above. As before, start with some white and mix in a small amount of ultramarine blue. Then add some orange – but mix in a tiny bit more orange than before.
How do you color the night sky?
Starting at the top of the painting gently dab purple around your galaxy to darken the night sky. Then do a layer of black, then blue. Each step will slowly fill in more of the sky. Generally the sky will be darker at the top and lighten as it descends down to the horizon.
How do you create a cloud?
Here’s what you do: Pour hot water into the jar. The water should be hot, but not to the point of boiling. Swirl the water to warm the jar. Place the lid upside down on top of the jar. Fill the lid with ice cubes. Remove the lid and quickly spray a bit of hairspray. Watch as the cloud forms inside the jar.
