Welcome To ClassWhy is a person working out and
sweats a lot more likely to get heat stroke when the humidity is high?
Agenda• Clouds notes• Demo• Cloud Classification
– Foldable Activity• Observe Clouds• Concept Map
Clouds• What is a cloud?
– Small water droplets or ice crystals suspended in the air
– Air is cooled and water vapor condenses
Clouds
How do clouds form?
• Water vapor condenses on condensation nuclei– Solid particle in the atmosphere that provides a
surface for water to condense– Ice, salt, dust, other particle
Cloud Formation
• Adiabatic Cooling –air mass temp. decreases as the air mass rises and expands
• Mixing – two masses of moist air meet and cool
Cloud Formation
• Lifting – forced upward movement of air that expands and cools
• Advective Cooling – air mass temp. decreases as the air mass moves over a cold surface
Types of Clouds
• Low Level – Stratus, nimbostratus, stratocumulus, some Cumulus
• Mid-level – Cumulus, altocumulus, altostratus
• High Level – Cirrus, Cirrostratus, Cirrocumulus
Key Cloud Terms• Nimbo, Nimbus – rain
• Alto – middle
• Stratus – layered
• Cumulus – cotton ball, fluffy look, heap
• Cirrus – feathery, curl of hair
Other Clouds
• Contrails – formed from exhaust from a jet
• Mammatus - pouch-like cloud structures and a rare example of clouds in sinking air– Seen after a storm
• Pileus Clouds – clouds found attached to a mountain top
Foldable Activity• Fold Paper in half
• Cut two lines (create 3 tabs)
• Label the tabs as Cumulus, Stratus, and Cirrus
• On the inside write information about each type of cloud
Cloud Observation• Keep a log of Clouds
Day Cloud(s) seen
