Which cloud type appears as thin, wispy filaments at high altitudes?
Stratus
Cumulus
Cirrus
Nimbostratus
Cirrus clouds form above 6,000 meters and are composed of ice crystals, giving them a thin, wispy appearance. They indicate moisture at high altitudes and do not produce significant precipitation.
Which cloud type is characterized by puffy, cotton-like appearance with a flat base?
Cirrostratus
Cumulus
Stratus
Cirrus
Cumulus clouds have a well-defined flat base and billowy tops due to rising thermals. They indicate convection and fair weather when small.
Which cloud type forms a uniform gray layer covering the sky and often produces light drizzle?
Stratus
Altocumulus
Cirrostratus
Cumulonimbus
Stratus clouds are low-level, featureless layers that often cover the entire sky and can produce light drizzle or mist. They form in stable air with weak vertical motion.
Cirrus clouds typically occur above what altitude?
3 km
1 km
6 km
2 km
Cirrus clouds are high-altitude clouds usually found above 6,000 meters (20,000 feet). Their composition of ice crystals requires colder temperatures found at those heights.
What is the primary composition of low-level stratus clouds?
Mixed-phase particles
Supercooled droplets only
Water droplets
Ice crystals
Stratus clouds at low altitudes are composed mainly of liquid water droplets. Ice crystals only form in clouds at subfreezing temperatures, typically above the freezing level.
Which cloud type is found at mid-level between 2 - 6 km and appears as a layer of white or gray puffy grains?
Cirrocumulus
Stratocumulus
Altostratus
Altocumulus
Altocumulus clouds form in the mid-level range (2 - 6 km) and appear as patches or layers of small, rounded masses. They differ from stratocumulus by altitude and from cirrocumulus by larger droplet size.
Which cloud indicates strong vertical air motion and an unstable atmosphere?
Stratus fractus
Cumulus congestus
Altocumulus lenticularis
Cirrostratus
Cumulus congestus clouds have towering, cauliflower-like tops indicating vigorous upward motion. Their vertical growth signals instability in the atmosphere.
Which cloud type is most associated with steady precipitation along warm fronts?
Cumulonimbus
Nimbostratus
Cirrus
Stratocumulus
Nimbostratus clouds form a thick, dark layer that produces continuous, steady precipitation. They develop ahead of warm fronts due to gentle, widespread ascent.
A halo around the sun or moon is often seen when which cloud type is present?
Altocumulus
Cirrostratus
Stratus
Cumulonimbus
Cirrostratus clouds contain ice crystals that refract light, creating halos around the sun or moon. They form high, thin sheets that often precede a warm front.
Which cloud formation is characterized by pouch-like structures hanging from the base of a cumulonimbus?
Undulatus
Lenticular
Castellanus
Mammatus
Mammatus clouds are bulbous protrusions on the underside of a cloud, commonly associated with the anvils of cumulonimbus. They indicate strong turbulence and moist air aloft.
Clear, calm nights often lead to formation of which cloud type near the surface due to radiative cooling?
Cumulonimbus
Cirrus
Altocumulus
Stratus
Radiative cooling at night can lower the surface temperature to the dew point, generating a thin layer of stratus clouds or fog. These clouds form in stable conditions.
How can you visually differentiate cirrocumulus from altocumulus clouds?
Cirrocumulus are darker and lower
Altocumulus form only as lenticular shapes
Altocumulus always produce halos
Cirrocumulus have smaller, tighter cells and appear at higher altitudes
Cirrocumulus clouds form above 6 km and appear as small, white patches without shadowing. Altocumulus are thicker, larger, and cast shadows due to greater droplet size.
A higher surface dew point leads to what change in cloud-base altitude?
Lower cloud base
No change
Cloud base becomes infinite
Higher cloud base
Cloud-base altitude is inversely related to dew point depression. A higher dew point (smaller depression) means the air reaches saturation sooner, lowering the cloud base.
Which process primarily forms raindrops in warm clouds above freezing?
Ice nucleation
Bergeron-Findeisen
Collision-coalescence
Sublimation
In warm clouds, larger droplets grow by colliding and coalescing with smaller ones until they are heavy enough to fall as rain. The ice-phase processes are minimal above freezing.
Which cloud type often forms on the windward side of mountains due to orographic uplift?
Altostratus
Cirrostratus
Stratocumulus
Lenticular
Lenticular clouds form as air is forced over a mountain ridge, creating standing waves. The cloud appears lens-shaped and stationary relative to the terrain.
A ragged, irregular fragment of low cloud lacking vertical development beneath a parent cloud layer is classified as which species?
Undulatus
Fractus
Castellanus
Humilis
The species 'fractus' refers to torn or ragged fragments typically found under a parent cloud. These appear irregular and lack significant vertical growth.
According to the approximate formula LCL (m) ≈ 125 × (T - Td), what happens to the lifting condensation level when the dew point depression decreases?
LCL height decreases
LCL height stays the same
LCL height becomes negative
LCL height increases
The LCL formula shows that as (T - Td) decreases, the product and thus the LCL height decreases. A smaller dew point depression means saturation is reached sooner.
Which cloud type is typically the first to appear about 24 hours before the arrival of a warm front?
Stratus
Cirrus
Cumulonimbus
Nimbostratus
Cirrus clouds are usually the earliest sign of an approaching warm front, forming in the moist, rising air ahead of the front. They often transition to cirrostratus and altostratus as the front nears.
Mid-level cloud bands aligned in parallel waves typically belong to which species?
Floccus
Undulatus
Castellanus
Lenticularis
The species 'undulatus' describes cloud formations in wave-like bands caused by atmospheric wave motions. This pattern is common in altocumulus undulatus.
A cloud observed at about 12,000 ft with a thin, fibrous appearance lacking shadows is classified as what genus and species?
Cirrocumulus castellanus
Stratus nebulosus
Cirrostratus fibratus
Altostratus translucidus
Cirrostratus fibratus are high-altitude, fibrous clouds without shadowing. They form above 6 km from ice crystals and create a veil-like appearance.

Cheat Sheet

  1. Four core cloud types - Clouds come in four main shapes: cirro-form (high and wispy), cumulo-form (fluffy and cotton-like), strato-form (layered like a blanket), and nimbo-form (rain-bearing). Learning these categories is like unlocking the secret code of the sky. Once you spot a cloud's form, you're well on your way to classifying it! The Four Core Types of Clouds
  2. Altitude ranges for cloud groups - Clouds are sorted by height into low (surface to 2 km), middle (2 km to 7 km), and high (5 km to 13 km) layers. Knowing these ranges gives you a quick "sky GPS" for identifying cloud types. Next time you look up, you'll know exactly which atmospheric layer you're gazing into! Cloud Types
  3. Cumulus clouds - These are the classic puffy, cotton-like clouds with flat bases, usually found below 2,000 m. They often signal fair weather but can stack up into towering giants that unleash thunderstorms. Keep an eye on their growth - you might just predict a surprise shower! Cumulus cloud
  4. Stratus clouds - Stratus clouds form a uniform gray sheet that can make the sky look like a giant lampshade. They hang low and often bring light drizzle or mist. If it feels like you're walking through a sea of fog, you're probably under a stratus blanket! Stratus cloud
  5. Cirrus clouds - High up at 6 - 13 km, cirrus clouds appear as delicate, wispy strands of ice crystals. They're nature's weather whisperers, often hinting at an approaching warm front. Spotting them early can give you a head start on tomorrow's forecast! Cirrus cloud
  6. How clouds form - Clouds are born when warm air rises, cools, and condenses water vapor into tiny droplets or ice crystals. This process depends on temperature, humidity, and atmospheric pressure. Mastering these basics turns you into a cloud-creation detective! How Clouds Form
  7. Atmospheric conditions and cloud development - Temperature gradients and humidity levels play starring roles in cloud growth. Unstable air can trigger towering cumulus clouds and dramatic thunderstorms. Understanding these factors adds superpowers to your weather-watching toolkit! Clouds and Weather
  8. Practice with real-world images - Nothing beats hands-on practice: study photos and diagrams to sharpen your cloud-spotting skills. Challenge yourself to name clouds in daily sky snapshots. The more you practice, the faster you'll become a cloud classification champ! Cloud Types Diagram
  9. Latin roots in cloud names - Cloud names often blend Latin words: "cirro" means curl, "alto" means mid-level, and "nimbus" means rain. Recognizing these roots helps you decode any cloud's mood and altitude. It's like learning a mini Latin lesson in every sky scan! Cloud Types
  10. Mnemonic devices for recall - Use fun memory aids - "Cows Say Moo" can remind you of Cirrus, Stratus, and Cumulus. Mnemonics turn complex lists into catchy phrases you'll never forget. With the right device, cloud classification becomes a breeze! Major Types of Clouds Formation and Their Characteristics
