• 4 kinds of fronts
•
•
•
•
Warm front
Cold front
Stationary front
Occluded front
• Each front has a symbol
• Side of the line the symbols are
on indicate direction of
movement
What does each front mean?
• Warm front – warm air is
replacing cold air
• Cold front – cold air is
replacing warm air
• Stationary front – air masses
are not moving due to similar
pressures
• Occluded front – warm air is
pushed up due to cold air
moving in from both directions
front animation
What happens when cold and warm air
meet?
• Cold air sinks and warm air
rises
• Warm air carries moisture
• Moisture condenses
• Clouds form
• Once air is saturated with
moisture, precipitation in
some form occurs
What happens before and after a warm front?
Before
After
• Cool or cold temps
• Falling barometer
• Increasing, thickening clouds
• Light to moderate precipitation
• Temp and dew point get closer
together
• Warm and more humid
• Clearing clouds
• Rising barometer
• Temp and dew point are close
What is dewpoint?
• The temperature at which
air is saturated enough
for water to condense
• High dewpoint –
temperature and
dewpoint are close
together
• Low dewpoint –
temperature and
dewpoint are far apart
• ALWAYS a dewpoint
What happens before and after cold fronts?
Before
After
• Warm
• Falling barometer

jet stream
Assignment!
• Predicting weather
• Edheads weather prediction
• We’ll do this as a group
Assignment!
• Complete the forecasting weather map worksheet
• Put in the box when you are finished
Clouds
How they form and what they mean
What happens as water evaporates?
• Humidity – the amount of water in
the air
• Amount of water vapor increases =
higher humidity
• Air pressure increases as amount of
water vapor increases
• Air is saturated when water entering
air = water returning to surface
• Warm air contains more vapor than
cold air
How is humidity measured?
• Using a hygrometer
• Relative humidity – ratio of
actual amount of water in
the air compared to the
amount of water air can
hold at that temperature
and pressure
• If amount of water vapor is
constant, what will happen
to the humidity if you raise
the temperature? Lower it?
So how do clouds form?
• Temperature can change
without heat input or loss
• These changes are called
adiabatic temperature
changes
• Happens when air is
compressed or expanded
• Expansion cools
• Compression warms
What happens to air and vapor as it rises?
• Overall, air resists lifting
• 4 factors make air light enough to be lifted
•
•
•
•
Oographic lifting
Frontal wedging
Convergence
Localized convective lifting
What is oographic lifting?
• Elevated terrain blocks air from
moving forcing it to go up and
over
• Causes the rainshadow effect
• Wettest places on the windward
side of mountain
• Lifting air reaches dew point and
condenses  clouds form  air is
pushed higher and forced to
release moisture as precipitation
• By the time air gets to the other
side of the mountain the moisture
has mostly been lost
What is frontal wedging?
• Air masses collide in flatter areas
• Area between two air masses is a front
• Cooler air sinks and warmer air rises  condenses  forms clouds
Brief Review
• What is a front?
• What are the 4 different types of fronts?
• Draw each front as it appears on a weather map.
• How does weather change as each front moves through?
What is convergence?
• Air in lower atmosphere collides
together and is forced upward
• Air converging from 2 different
directions must go somewhere,
down is not an option
• Example
• Ocean winds blow toward the
shore
• In Florida, this happens on both
sides of the state so air flows
together
• Produces many afternoon storms
What is localized convective lifting?
• Due to unequal heating of
Earth’s surface
• Causes pockets of air to be
warmer than surrounding air
• Example: parking lots
• Warm air will rise creating
thermals
• Birds and hang-gliders use these
to glide higher with less energy
• Warm air rises  reaches
dewpoint  clouds form

questions
• Turn in when you are finished
What is the difference in stable and unstable
air?
• Air is forced to rise and its
temperature is lowered by
expansion
• Cooler air sinks to its original
position – stable
• If it does not sink to its original
position – unstable
• Bad weather
• stable vs. unstable air
What’s the difference in stable and unstable
air rising?
• Stable air resists vertical movement but some factors force it to rise
• What are the 4 things that can make air rise?
• When stable air rises – clouds are widespread and thin
• Unstable air rising – clouds are thick and cover a small area
• thunderstorms
What makes air density different?
• Temperature
• Warm – rises
• Like hot air balloons
• Cool – sinks
• Elevation
• High – air is less dense
• Particles far apart
• Low – air is more dense

How does water condense to make clouds?
• Usually a surface for cooling
water to condense on
• Bacteria
• Small particles – dust, soot,
particles of pollution

Cloud types
How are clouds categorized?
• Based on height and form
• 3 main types
• Stratus
• Cumulus
• Cirrus
What are cirrus clouds?
• High, white, and thin
• Patches or wispy fibers – may
appear feathery
• 3 types
• Cirrus
• Cirrostratus – flat layers
• Cirrocumulus – fluffy masses
• Usually signify nice weather
• When replaced by cirrocumulus
clouds and increased coverage –
sign of bad weather approaching
What are cumulus clouds?
• Piles of clouds
• Rounded cloud masses
• Normally with flat base in domes or
towers
• middle clouds
• 2 other types of middle clouds
• Alto – prefix meaning middle
• Altocumulus – rounded masses that are
larger and more dense than cirrocumulus
• Altonimbus – uniform white – greyish
sheet, sun or moon visible as a bright spot
• Often snow or rain accompany these
What are stratus clouds?
• Low clouds
• Sheets or layers
• No distinctive cloud masses
• 2 other types of low clouds
• Stratocumulus – long parallel
with a rolling bottom
• Nimbostratus – main
precipitation markers form in
stable conditions
Are there any clouds that reach through
several cloud layers?
• Low bottoms with tops that
reach into the high regions
• From unstable air
• Cumulonimbus
• Usually grown from cumulus
clouds and signify storms
Do clouds ever touch the ground?
• Fog is a cloud with its base on
or near the ground
• No physical difference with
any other cloud
• Difference is in placement and
formation
• Usually the result of warm air
moving over a cooled surface
• Can form when cool air moves
over warm water – steamy
appearance
• Forms when enough water
vapor brings about saturation
How does precipitation form in cold clouds?
• Supercooling and supersaturation –
Bergeron process
• Cloud droplets do not freeze at 0°C,
instead it must be about -40°C supercooled
• Freezing nuclei cause water droplets to freeze
• Greater than 100% humidity –
supersaturated
• Ice and water cannot exist together in clouds
• Evaporating water quickly produces
snowflakes or ice
How does precipitation form in warm clouds?
• Rainfall in clouds is well
below freezing – even in
tropics
• Collision – coalescence
process – water absorbing
particles remove moisture
forming large droplets
• Drops collide and mix with
smaller slower droplets
Does ice form in warm clouds?
• Hail
• Forms in cumulonimbus
clouds
• Starts small
• Updrafts carry hail
through supercooled
layers repeatedly
• Forms layers

•
•
•
•
•
Tell what each source is
What do they do to cause climate change
3 ways to counteract the effects of natural climate change
3 ways to reduce impact from the human induced problems
What additional problems does this cause for the biosphere (at least 2)
• Due the day before test day (Dec 19)
What is the difference in climate and
weather?
• Weather
• State of the atmosphere at a
given time
• What atmospheric layer does
this happen in?
• Climate
• Average weather patterns over a
LONG period of time
How is climate classified?
• Köppen classification
• 3 major climate systems
• Temperate
• Tropical
• polar
What is a temperate climate?
• Moderate changes between seasons
• Distinct summers and winters
• Between 20 and 65 degrees north and south of the equator
What is a tropical climate?
• Constant warm
temperatures with high
precipitation
• Around the equator
between 0 and 25 degrees
What is a polar climate?
• Constant cold temperatures
• 24 hours of daylight in summer and 24 hours of dark in winter
• Treeless tundras or glaciers
How are humans causing climate change?
• Burning fossil fuels and cutting
down trees increases gases such as
carbon dioxide, carbon monoxide,
and ammonia in the atmosphere
• These gases act as a blanket and
retain radiation from the sun in the
form of heat – the greenhouse
effect
• Gases responsible for this effect are
greenhouse gases
• Some CO2 is necessary to keep Earth
warm enough for life
greenhouse effect - Futurama
Isn’t CO2 absorbed by the ocean?
• Yes by diffusion
• Some of this carbon reacts
with water to form weak
carbonic acid
• Makes the shells of marine
creatures thinner
• Increases vulnerability
• Decreases our food source
• How will increased CO2
affect sea level?
Are there natural phenomena that cause
climate change?
• Yes
•
•
•
•
•
Sunspots
Volcanic activity
El Niño and La Niña
Shifts in orbit
Naturally fluctuating CO2 levels
How do sunspots cause climate change?
• Controversial
• Sunspots are dark spots on the
surface of the sun
• Increase in sunspots correlates to an
increase in temperature and vise
versa
• Spots are cooler spots in the sun and
area around them warms to make up
for the difference
• Less spots = more solar wind = more
clouds = less sun hitting Earth
How do volcanic eruptions cause climate
change?
• Massive amounts of gas, ash,
and aerosol released into the
atmosphere
• Ash falls rapidly
• Gas stays in the upper
atmosphere
• Sulfer dioxide reflects light back
into space – causes cooling
• CO2 causes warming –
greenhouse effect
How do El Niño and La Niña influence climate
change?
• What are trade winds like in a typical
year on the western coast of
continents?
• What do these winds do to warm
water?
• Temporary change in Pacific Ocean
around the equator
• Affects Northern hemisphere’s winter
• Area of typical thunderstorms moves
eastward
• Due to a reduction of upwelling in the
eastern ocean
What about La Niña?
• Opposite of El Niño
• Caused by cooler surface temperatures
What are the results of El Niño?
• Wet winters in southeast US
• Droughts in Indonesia and
Australia
• Weaker winds to further
reduce upwelling and cause
El Niño to grow – positive
feedback
• Irregular but generally
happen every 3-7 years
How does a shift in Earth’s orbit produce
climate change?
• What is precession? How does it
affect climate?
• What is nutation? How does it
affect climate?
• Eccentricity – distance between
Earth and Sun
• Varies slightly as the barycenter of
the sun changes position
• Long term effects – triggers
beginnings and ends of ice ages
How does CO2 fluctuation change climate?
• Higher levels of CO2
contribute to the greenhouse
effect
• Higher levels = higher
temperatures
• Natural as well as human
influenced
• Volcanoes and burning fossil
fuels
• Seasonal – higher levels in the
winter… why?
Do gases do anything else to affect climate?
• Some dissolve easily
in water to make acid
rain
• Nitrogen oxide
• Sulfur dioxide
• Can be carried far by
winds and affect
areas far away from
where it developed
Are there any other human affects on our
atmosphere?
• Chlorofluorocarbons (CFCs) – only
created by humans, found in old
aerosol cans (hairspray etc…)
• Destroy ozone
• 1 CFC can destroy thousands of
ozone particles
• No longer used or made in America
• Created a large hole in ozone over
Antarctica – conditions here have
begun to improve
What are aerosols and what do they do?
• Small particles suspended
in the atmosphere
• In high amounts they can
scatter sunlight and
prevent it from reaching
Earth
• Common in any aerosol can
(hair spray, cool whip, can
cheese etc…)
• Also natural – volcanoes,
meteors
How is climate change affecting the
biosphere?
• If the climate warms faster than organisms can adapt to it they will
become extinct
• Mass extinction if we lose many species within a few centuries
• Ecosystems will lose balance as organisms die
• Insects are able to migrate to higher elevations – mosquitos
• Agriculture will become difficult as weather warms and rains decrease
What can you do to stop climate change?
• Decrease dependence on fossil fuels
•
•
•
•
•
•
•
•
•
•
Walk or ride a bike
