GHY104 Test 3 With
Complete Solution
Cloud - ANSWER Aggregation of tiny moisture droplets and ice crystals
suspended in air, great enough in volume and concentrations to be seen.
Fog - ANSWER A cloud that is in contact with the ground.
Collision-coalescence process - ANSWER Describes precipitation (rainfall) and
involves moisture droplets colliding together.
Bergeron process - ANSWER Involving super-cooled water droplets which
evaporate and absorbed by ice crystals. occurs in the higher parts of the
troposphere.
Altitude and shape - ANSWER The key to cloud classification
3 basic cloud forms - ANSWER flat, puffy, and wispy
4 altitude classes - ANSWER low, middle, high. and vertically developed
10 basic cloud types - ANSWER Altocumulus, Cirrocumulus, Nimbostratus,
stratus, cirrostratus, altostratus, lenticular, cirrus, cumulus, cumulonimbus
Low clouds (up to 200m) - ANSWER Stratus, Stratocumulus, nimbostratus
Middle clouds (2000-6000m) - ANSWER altostratus, altocumulus
high clouds (6000-13000m) - ANSWER Cirrus, cirrostratus, cirrocumulus
Vertically developed clouds (near the surface to 13000) - ANSWER cumulus,
, cumilonimbus
Stratus (low) - ANSWER uniform, featureless, gray clouds that look like high
fog
Stratocumulus (low) - ANSWER soft, gray, globular cloud masses in lines,
groups, or waves
nimbostratus (low) - ANSWER gray, dark, low clouds with drizzling rain
Altostratus (middle) - ANSWER thin to thick clouds, with no halos. Sun's
outline just visible through clouds on a gray day
Altocumulus (middle) - ANSWER Clouds like patches of cotton balls, dappled,
and arranged in lines or groups
Cirrus (high) - ANSWER "Mare's tails" clouds. wispy feathery, with delicate
fibers, streaks, or plumes
Cirrostratus (high) - ANSWER Clouds like veils, formed from fused sheets of
ice crystals, having a milky look, with sun and moon halos
Cirrocumulus (high) - ANSWER dappled clouds in small white flakes or tufts.
Occur in lines or groups, sometimes in ripples, forming a "mackerel sky"
Cumulus (vertical) - ANSWER sharply outlined, puffy, billowy, flat-based
