ATMO 201 EXAM 2 CERTIFICATION SCRIPT
2026 QUESTIONS WITH ANSWERS GRADED
A+
◉ wet bulb temperature. Answer: Lowest temperature reached by
evaporating water into the air
◉ Heat index. Answer: Combines air temperature with relative
humidity to determine apparent temperature
◉ Dew formation. Answer: Forms on objects near the ground
surface when they cool below the dew point temp, more likely on
clear nights
◉ White frost formation. Answer: Forms when the dew-point
temperature is at or below freezing, goes from vapor straight to ice
◉ When does white frost form. Answer: Cold, clear, calm mornings
◉ Haze. Answer: Layer of particles dispersed through a portion of
the atmosphere. Visible >1 mile
,◉ Fog. Answer: If saturation is reached, condensation forms a cloud
with its base at earth's surface. Visible <7 miles
◉ Cooling (fog formation). Answer: Air is cooled below its saturation
point (dew point)
◉ Evaporation and mixing (Fog formation). Answer: Water vapor is
added to the air by evaporation, and the moist air mixes with
relatively dry air
◉ Radiation fog. Answer: Clear, calm nights with drier air over cool,
moist air at surface
◉ Advection fog. Answer: Wind moves warm, moist air over cold
surface and moist air cools to dew point
◉ Prime location of dense fog. Answer: Prevalent in coastal margins
near the Great Lakes and Appalachian Mountains
◉ Dense fog causes. Answer: extremely limited visibility, airports
suspend flights
◉ Four forms of clouds. Answer: stratus, cirrus, cumulus, and
nimbus
, ◉ Four primary cloud groups by height. Answer: High, middle, low,
and vertical
◉ High clouds. Answer: cirrostratus, cirrus, cirrocumulus
◉ Middle clouds. Answer: altostratus, altocumulus
◉ Low clouds. Answer: stratus, stratocumulus, nimbostratus
◉ Vertical clouds. Answer: cumulus, cumulonimbus
◉ Height of high clouds. Answer: 10,000-43,000ft
◉ Height of middle clouds. Answer: 6,500-26,000ft
◉ Heigh of low clouds. Answer: surface-6,500ft
◉ Cloud: Thin and Wispy, indicates fair weather. Answer: Cirrus
◉ Cloud: small, rounded white puffs individually or in long rows
(fish scales). Answer: Cirrocumulus
