Weather and the Atmosphere
2
What is weather?

• Weather is the state of the atmosphere at a given
  time and place
• Meteorology is the study of the entire
  atmosphere

3
Observing the weather

• Beaufort Scale this scale relates wind speed to
  its effects

4
Four Layers of the atmosphere

• Troposphere
• Temperature falls
• (Tropapause) is where the highest clouds appear
• Stratosphere (Ozonosphere)
• Temperature rises
• Weather is constant
• (Stratopause) border of stratosphere/mesosphere
• Mesosphere
• Temperature falls
• (lonosphere starts halfway through the mesosphere
  thru thermosphere
• (mesopause)borders the mesosphere thermosphere
• Thermosphere
• Temperature rises
• Meteors
• auroras

How does the heat move?

• Radiation
• Hot bodies such as the sun radiate their energy
  mainly in the forms of short waves
• Conduction
• An object receives heat when it comes into
  contact with a hotter object.
• Convection
• Transfers heat from one place to another
• This is the most effective form of heat transfer
  in liquids and gases

Heat balance of Earth and the Atmosphere

• Heat budget
• Ideally as much energy that enters the Earth
  would leave the Earth
• Sun
• The suns rays expand throughout space, and we
  only receive 1 / 2,000,000,000 of the suns rays
• This incoming radiation is known as insolation

So what we look like is
12
What can we do to stop this?

• CFCs
• Fumes
• Buses
• Cars
• Pollution (factories)

13
What does that mean ?

• All right we become more like CA, FL
• Life would just be a little hotter
• Life as we know it would be gone
• The temperature of the water would change.
• WHICH IS IT OR IS IT MORE THAN ONE????????
