Title: Weather Unit Foldable


1
Weather Unit Foldable
  • In the upper right hand corner write
  • Your name
  • Today's date
  • Core

2
Yellow Paper Title The Atmosphere
  • What is the atmosphere?
  • What is the function of the atmosphere?
  • The atmosphere is
  • layers of gasses that
  • surround the Earth.
  • Earths atmosphere has
  • two main functions 1st it
  • contains gas like O2 that
  • we need to live and 2nd it
  • traps heat so the water on
  • the planet remains liquid.

3
The Atmosphere
  • What gases are in the atmosphere?
  • There are 2 main gases
  • in the atmosphere
  • 1st Nitrogen 78
  • 2nd Oxygen 21.
  • All other gases make up
  • the other 1.

4
Green Air Pressure
  • What is air Pressure?
  • What is Barometric pressure?
  • The result of the weight
  • of a column of air pushing
  • down on an area.
  • Changes in the atmospheric pressure as shown by a
    barometer

5
Air Pressure
  • What are the Properties of air?
  • Altitude/Elevation
  • How does altitude affect air pressure and density?
  • Air has mass, density, and pressure.
  • The distance above sea level. (the surface of
    the ocean)
  • The higher the altitude the lower the air
    pressure and denisty
  • The lower the altitude the greater the air
    pressure and density.

Blue Title Layers of the Atmosphere
  • How many layers are there in the atmosphere?
  • There are 5 layers, the troposphere,
    stratosphere, mesosphere, thermosphere, and
    exosphere,

8
Layers of the Atmosphere
  • Troposphere
  • - This is the layer we live in and the
    smallest layer
  • Temperature decreases as altitude increases 140
    to - 76 degrees F
  • All weather happens here
  • This is the ONLY layer living things can live in
  • 16 km above sea level

9
Layers of the Atmosphere
  • Stratosphere
  • Temperature increases as altitude increases from
    -76 to 32 degrees F
  • - Ozone layer found here, and weather Balloons
  • 50 km above the earth

10
Layers of the Atmosphere
  • Mesosphere
  • - Temperature decreases to coldest point 32
    to -130 degrees F.
  • - Meteor Showers
  • - 50 to 90 km

11
Layers of the Atmosphere
  • Thermosphere
  • - Temperature increases 2700 degrees F
  • - Aurora borealis (Northern lights),
    International Space Station, Space Shuttle stay
    in this layer.
  • - 90 to 500 km from sea level

12
Layers of the Atmosphere
  • Exosphere
  • - Temperature Increases to 5000 degrees F
  • - Satellites orbit here
  • - 500 km from sea level
  • Meteorology - is the study of the earths
    atmosphere

13
Orange title Air Masses and air Fronts
  • Air Mass
  • Air always move from areas of high pressure to
    areas of low pressure.
  • On the surface of earth air moves from the poles
    to the equator. In high atmosphere air move to
    the poles
  • A huge body of air that has similar temperature,
    humidity, and air Pressure.

14

15
  • There are 5 types of air masses classified by
    temperature, and humidity.
  • Continental dry
  • Maritime wet
  • Tropical warm
  • Polar cooled
  • Artic Super cold
  • The pacific ocean currents influence the weather
    of Utah. How?

Orange Title Air Masses and Fronts
  • What is a Front?
  • There are three main types of Fronts
  • An area where air masses meet and dont mix.
  • Cold Front
  • Warm Front
  • Stationary Front

21
Air Masses and Fronts
  • Cold Front Cold air moves underneath warm air,
    forcing warm air to rise.
  • Usually short violent storms
  • Page 605

22
Air Masses and Fronts
  • Warm Front Forms when warm less dense air rises
    over cold air.
  • Precipitation usually far ahead of the front.

23
Air Masses and Fronts
  • Stationary Front happens when a cold and warm
    air mass meet and dont move.

24
Orange 2 Title Weather Factors
  • Radiation the transfer of energy by
    electromagnetic waves
  • Conduction heat transferred through a substance
    by the direct contact of molecules.
  • Convection Currents the transfer of heat by the
    movement of a heated fluid.

25
Orange 2 Title Weather Factors
  • Weather is caused by heat energy, moister, wind,
    air pressure.
  • The ozone layer absorbs powerful ultraviolet
    radiation from the sun.
  • Green house effect process by which gases hold
    heat in the air. CO2

26
Orange 2 Title Weather Factors
  • Temperature the average amount of energy of
    motion of the molecules of a substance.
  • Heat the transfer of energy from a hotter
    substance to a cooler one.

27
El Nino
  • El Nino - (El Nee-nyo) is the warming of water in
    the Pacific Ocean.
  • El Nino Weather
  • Rain and flooding along the Pacific coast
  • Warm water disrupts food chain of fish, birds,
    and sea mammals
  • Tornadoes and thunderstorms in southern US
  • Fewer than normal hurricanes in the Atlantic

28
  • La Nina - (Lah Nee-Nyah) is the cooling of water
    in the Pacific Ocean.
  • La Nina Weather
  • Snow and rain on the west coast
  • Unusually cold weather in Alaska
  • Unusually warm weather in the rest of the USA
  • Drought in the southwest
  • Higher than normal number of hurricanes in the
    Atlantic

29
Blue Title Wind
  • Wind the horizontal Movement for air from an
    area of high pressure to an area of low pressure.
  • All wind is caused by differences in air
    pressure.
  • Wind is named by the direction from which it
    comes from.

30
Global Wind Patterns
31
Blue Title Wind
  • Jet Stream bands of high-speed winds about 10km
    above earths surface.
  • Prevailing Westerlies mid-latitude, wind that
    blow from West to East.

32
Green Title Precipitation
  • Precipitation any form of water that falls from
    the clouds and reaches Earths surface. (liquid
    or solid)
  • There are 5 common types of precipitation
  • Water
  • Sleet
  • Freezing Rain
  • Hail
  • snow

33
Green Title Precipitation
  • Humidity measure of the amount of water vapor in
    the air
  • Water vapor water in the form of a gas
  • Moist air is more dense then dry air
  • Liquid water in more dense then water vapor
  • Warm air holds more water vapor then cold air
