There both if you think about them.
Basically, they usually have calm weather with them, nothing like heavy snow or severe thunderstorms. however, they cna produce light precip of mist/drizzle, low ceilings/fog for aircrafts.

"Stratus" is Latin for layer or blanket. The clouds consist of a feature-less low layer that can cover the entire sky like a blanket, bringing generally gray and dull weather. The cloud bases are usually only a few hundred feet above the ground. Over hills and mountains they can reach ground level when they may be called fog. Also, as fog "lifts" off the ground due to daytime heating, the fog forms a layer of low stratus clouds.

A Stratus cloud (St), derived from the Latin word meaning "spread out", is a cloud belonging to a class characterized by horizontal layering with a uniform base, as opposed to convective clouds that are as tall or taller than wide (these are termed Cumulus clouds). More specifically, the term Stratus (abbreviated St) is used to describe flat, featureless clouds of low altitude (below 6,500–8,000 feet or 2,400 meters) varying in colour from dark gray to nearly white. These clouds are essentially fog that is above ground level and are formed either through the lifting of morning fog or when cold air moves at low altitudes over a region. These clouds do not usually bring precipitation, although if sufficiently low in altitude to become fog, drizzle or mist may result.
Stratus formations that are accompanied by precipitation are known as nimbostratus. Stratus formations at higher altitudes include altostratus and cirrostratus.

A Stratus cloud takes the form of big and fluffy but still kinda flaky looking at the same time, but usually with a dark tint, kinda like fog. With stratus clouds, tends to come storms; rain, snow, sleet, etc. Cirrostratus is the thin elongated flaky clouds that are almost see through, and do not typically come with storms!

i comprehend that you've requested previously yet ... it is amazingly elementary: Air that sinks (cut back in altitude) warms up with techniques from the adiabatic results of a larger stress at decrease altitude. it is an identical idea that pumps a coolant on your refrigerator (arising warmth) then launch it with the help of a nozzle (arising chilly). that is termed the adiabatic result. As a parcel of air warms up, its moisture evaporates and clouds dissolves. this is what ensue in a extreme stress, the sky is sparkling because the sinking air has dissolved all clouds. Fog ensue even as there is an inversion, i.e. hotter air above less warm one. The air doesn't upward thrust and there's no convection. If the floor is amazingly chilly, because it receives at nighttime even as warmth radiates decrease back into area, the air accurate above the floor cools down till it reaches dew element and droplet of moisture kinds. this is fog! Fog may also ensue over the sea even as a modern of chilly water brings less warm air from lower than. Fog may also ensue even as moist air cools down with techniques from being lifted over a mountain. that is then suggested as orographic fog and it appears like fog on the hill yet like clouds interior the valley. Stratus clouds are layered clouds coming from distinct inversions at distinct tiers of altitude. frequently, they climb as they do over a warmth the front. yet, might want to they sink, they could evaporate quite quickly. in truth, as a fashion to stay, a cloud ought to upward thrust no matter if very slightly. A cloud it truly remains at an altitude and hence a consistent temperature finally ends up with techniques from evaporating. Even ice evaporates! that is then suggested as, sublimation.

An Altocumulus is a cloud belonging to a class characterized by globular masses or rolls in layers or patches, the individual elements being larger and darker than those of cirrocumulus and smaller than those of stratocumulus. These clouds are of medium altitude, about 8000-20,000 ft (2400-6100 m). A middle cloud, usually white or gray, often occurs in layers or patches with wavy, rounded masses or rolls. Altocumulus often are seen preceding a cold front, and their presence on a warm, humid, summer morning frequently signals the development of thunderstorms later in the day.
A stratocumulus cloud belongs to a class characterized by large dark, rounded masses, usually in groups, lines, or waves, the individual elements being larger than those in altocumuli, and the whole being at a lower altitude, usually below 2,400 m (8,000 ft). Weak convective currents create shallow cloud layers because of drier, stable air above preventing continued vertical development.
Generally stratocumuli bring no precipitation or only drizzle / light rain or snow at best. However, these clouds are often seen at either the front or tail end of worse weather, so may indicate storms to come, in the form of thunderheads or gusty winds.
These are similar in appearance to altocumuli and are often mistaken for such. A simple test to distinguish these is to compare the size of individual masses or rolls: when pointing your hand in the direction of the cloud, if the cloud is about the size of your thumb, it is altocumulus; if it is the size of your entire hand, it is stratocumulus.
A Nimbostratus is a cloud of the class characterized by a formless layer that is almost uniformly dark gray; it is a rain cloud of the layer type, of low altitude, usually below 8000 ft (2400 m). Nimbostratus clouds completely block the sunlight. Compare nimbostratus clouds with stratus, altostratus and cirrostratus. Nimbostratus clouds usually bring precipitation.
