Bellringer-Day 01
What do you think of when you hear the word
“atmosphere?”
What events do you think take place within
the atmosphere?
Do you know any layers/parts of the
atmosphere? If so, what?

Our atmosphere
Earth’s atmosphere = the layer of gases that surround the planetVery thin layer, relative to size of planet Atmosphere:
Absorbs solar radiation
Burns up meteors
Transports and recycles water, and other chemicals
Moderates climate

Layers of the Atmosphere
The atmosphere is divided into four layers based on temperature:1. Troposphere
2. Stratosphere
3. Mesosphere
4. Thermosphere
![Page 6: What events do you think take place within the atmosphere ...msfarrisscience.weebly.com/uploads/2/6/3/9/26394241/atmosphere_part_1.pdfBellringer-Day 01 What do you think of when you](https://reader030.vdocuments.us/reader030/viewer/2022040805/5e442b3f64f2400dad04eae2/html5/thumbnails/6.jpg)
As we continue…
Fill out your Layers of the Atmosphere Chart in your notes
•Be sure to include• Temperature change according to elevation
• Special characteristic of that layer
• Drawing which helps you remember the layer name with its characteristics

The Troposphere
The bottom layer, at Earth’s surface
11 km high.
Temperature decreases with altitude.
Where weather occurs
![Page 8: What events do you think take place within the atmosphere ...msfarrisscience.weebly.com/uploads/2/6/3/9/26394241/atmosphere_part_1.pdfBellringer-Day 01 What do you think of when you](https://reader030.vdocuments.us/reader030/viewer/2022040805/5e442b3f64f2400dad04eae2/html5/thumbnails/8.jpg)
The Stratosphere
◦ Next layer up (11–50 km).
◦ Temperature increases with altitude.
◦ Contains “ozone layer.”
◦ Why do you think planes fly in the stratosphere?
![Page 9: What events do you think take place within the atmosphere ...msfarrisscience.weebly.com/uploads/2/6/3/9/26394241/atmosphere_part_1.pdfBellringer-Day 01 What do you think of when you](https://reader030.vdocuments.us/reader030/viewer/2022040805/5e442b3f64f2400dad04eae2/html5/thumbnails/9.jpg)
The Mesosphere
Third layer up
(50–90 km).
Temperature
decreases with
altitude.

The Thermosphere
Top layer (90–500
km).
Very thin air;
mostly lightweight
elements.
Very hot.

Ozone layer
Not really a layer (it’s part of the stratosphere), but a region of higher-than-normal ozone concentrations (which are still very low)
~17–30 km altitude
Ozone = O3—molecule of 3 oxygen atoms
Absorbs ultraviolet (UV) radiation from sun, protecting organisms on surface from radiation damage

What is Meteorology?
The study of weather, climate, and atmosphere processes
![Page 16: What events do you think take place within the atmosphere ...msfarrisscience.weebly.com/uploads/2/6/3/9/26394241/atmosphere_part_1.pdfBellringer-Day 01 What do you think of when you](https://reader030.vdocuments.us/reader030/viewer/2022040805/5e442b3f64f2400dad04eae2/html5/thumbnails/16.jpg)
How Does Weather
differ from Climate?
Weather is constantly changing and it refers to the state of the atmosphere at any given time and place
Climate is based on observations of weather that have been collected over many years to help describe a place or region

Air Density Like most substances, cold air is more dense than warm air
Cold air will sink, hot air will rise….sound familiar??

Pressure Systems
Low pressure –warm air rises
Poor Weather-Clouds and
precipitation
High pressure – cool air sinks and
spreads
Fair weather

Wind is caused by the movement of air
molecules
Cool dense air sinks, forcing warm, less
dense air upward
Wind

Global Winds
The atmosphere balances itself
by acting as a giant heat-
transferring system
It moves warm air to the poles
and cool air towards the
equator
Jet Streams –
High altitude, westerly winds
Responsible for most of our
weather in our country!

Air Masses
Air masses are large bodies of air that take on characteristics of area they
cover (land and water)

Measuring Humidity
▪ Instrument: Hygrometer▪ Psychrometer : a type of
hygrometer consisting of two identical thermometers mounted side by side
▪ Dry bulb: give the present air temperature
▪ Wet bulb: has thin wet wick tied around the end

Cloud Formation
▪ Condensation Nuclei – small particles in atmosphere
which water condenses around
– Millions = cloud
▪ Coalescence – droplets collide, become bigger
▪ Precipitation – droplets become too big and fall

Weather Models In reading weather data, we can find all of the following through reading a
weather model
Temperature
Dew Point
Cloud Cover
Present Weather
Wind Speed
Wind Direction
Location
Atmospheric Pressure (mb)

Using Weather Models
Temperature
on the model
is measured
in degrees
Fahrenheit

Using Weather ModelsDew point is in
Fahrenheit
Cloud cover is
represented by the
amount of the circle
that is blacked out

Using Weather ModelsPressure measured in
millibars- also measured
by isobars on the map
For the pressure,
remember to add the
decimal point
between the 2nd & 3rd
digit, then put a 9 or
10 in front of it. The
acceptable range of
pressures is 960mb
to 1040mb.

Using Weather Models
Wind speed is measured
by lines
-Long lines are 10 knots
-Short lines are 5 knots
![Page 58: What events do you think take place within the atmosphere ...msfarrisscience.weebly.com/uploads/2/6/3/9/26394241/atmosphere_part_1.pdfBellringer-Day 01 What do you think of when you](https://reader030.vdocuments.us/reader030/viewer/2022040805/5e442b3f64f2400dad04eae2/html5/thumbnails/58.jpg)
Using Weather ModelsWind direction is
designated as the
area the wind is
blowing from!
The arrow is pointing NE,
so the wind direction is
“from the NE”

Pressure Differences Isobars
lines on a map that connect places of equal air pressure
A pressure gradient
The spacing of isobars
indicates the amount
of pressure change
over a given time

Isobars Closely spaced isobars:
indicate a steep pressure
gradient and high winds.
Widely spaced isobars:
indicate a weak pressure
gradient and light winds.

Thunderstorms• Generates lightning and thunder
• Frequently produce gusty winds, heavy rains, and hail
– 45,000 a day across the world
![Page 69: What events do you think take place within the atmosphere ...msfarrisscience.weebly.com/uploads/2/6/3/9/26394241/atmosphere_part_1.pdfBellringer-Day 01 What do you think of when you](https://reader030.vdocuments.us/reader030/viewer/2022040805/5e442b3f64f2400dad04eae2/html5/thumbnails/69.jpg)
• Lightning: results from the build up and discharge of electric energy between positively charged ground and negatively clouds.
• Thunder: the sound of rapidly expanding gases usually associated with lightning

Development of Thunderstorms
• Warm, humid air rises in unstable environment
• Uplift carries warm, moist air into cooler part of atmosphere
• 3 Stages
–Cumulus Stage
–Mature Stage
–Dissipating Stage

Thunderstorm Development• 1. Cumulus Stage-Precipitation will stay
uplifted until heavier than uplift force

Thunderstorm Development
• 2. Mature Stage-Downdrafts throughout the cloud (cold air)
• 3.Dissapating Stage-Storm dies

Tornados• Take form of rotating column of air called
vortex
• Uplift turns vortex vertical

Tornado Intensity
• Pressure inside lower than outside
– Air rushes in to equalize pressure
– Winds may reach 480 km/h (300 mph)
