What cloud types would indicate convective turbulence?
unstable, moist air
.
What type of clouds are a visual indication of convective turbulence?
Thunderstorms and
fair-weather cumulus clouds
make for excellent warnings of convective turbulence both in and around the cloud, but pilots should expect to encounter turbulent conditions within clouds at frontal boundaries or anywhere where there is a sudden change in weather conditions.
What clouds indicate turbulence?
If you see a
stratocumulus cloud
, expect some associated turbulence. If you see a cumulus cloud, first note whether or not it has vertical development. A cumulus with little vertical development means you can expect some turbulence. However, a towering cumulus cloud means you can expect very strong turbulence.
What clouds have greatest turbulence?
The clouds with the greatest turbulence are
cumulonimbus clouds
. Cumulus clouds are often a sign of good weather, but when cumulus clouds are filled…
What is the 4 types of cloud?
The different types of clouds are
cumulus, cirrus, stratus and nimbus
.
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.
Where is clear air turbulence strongest?
Any CAT is strongest on
the cold side of the jet stream
where the wind shear is greatest. In the vicinity of a jet stream, CAT can be encountered anywhere from 7,000 feet below to about 3,000 feet above the tropopause.
Do clouds cause turbulence on a plane justify?
Turbulence When Flying Through Clouds
Clouds are made up of tiny water droplets formed by rising water vapour as it cools. … These cloud-borne updrafts and downdrafts result in rapid and
unpredictable changes
to the lift force on the wings of an aircraft.
What is the highest cloud ever recorded?
Noctilucent clouds | Noctilucent clouds over Kuresoo bog, Viljandimaa, Estonia | Abbreviation NLC/PMC | Altitude 76,000 to 85,000 m (250,000 to 280,000 ft) | Classification Other |

Do clouds always cause turbulence?
When clouds generate showery precipitation, light,
moderate, or greater turbulence should
be expected. … Towering cumulus, cumulonimbus, and thunderstorms almost always equal strong convective turbulence both in and around the cloud.
Do pilots avoid clouds?
Pilots will actively avoid taking the aircraft into Cumulonimbus type clouds
as they can be hazardous to aviation. They can be very turbulent due to the updrafts and downdrafts, contain icing, heavy rain and hail and lightning.
What do lenticular clouds mean?
A lenticular cloud is
a lens-shaped cloud that normally develops on the downwind side of a mountain or mountain range
. This occurs when stable, moist air flows over a mountain, creating a series of oscillating waves.
How are clouds divided into four families?
For identification purposes, you need be con- cerned only with the more basic cloud types, which are divided into four “families.” The families are:
high clouds, middle clouds, low clouds, and clouds with extensive vertical development
.
What is the rarest cloud?
Kelvin Helmholtz Waves
are perhaps the rarest cloud formation of all. Rumored to be the inspiration for Van Gogh’s masterpiece “Starry Night”, they are incredibly distinctive. They are mainly associated with cirrus, altocumulus, and stratus clouds over 5,000m.
What is a dark cloud called?
Nimbostratus clouds
are dark, gray clouds that seem to fade into falling rain or snow. They are so thick that they often blot out the sunlight. Weather prediction: Gloomy with continuous rain or snow.
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.
