Term
| How is pressure measured and why does pressure decrease with altitude? |
|
Definition
p=mg (massxgravity)
pressure decreases with altitude because the mass above us decreases with altitude |
|
|
Term
| Explain the hydrostatic equation |
|
Definition
| The hydrostatic equation states that dp/dz = pz+change in p |
|
|
Term
| Write down the equation of state and breifly explain what it defines |
|
Definition
p=pRT
where R is the gas constant for air |
|
|
Term
| Define what an adiabatic process is |
|
Definition
| A process where energy is is conserved without the addition or subtraction of external energy |
|
|
Term

Term
| What does it mean that the earth is not in radiative equilibrium? |
|
Definition
| This means that the earth has more solar heating than longwave radiation on average |

Term
| What is the difference between a stable and non-stable atmosphere? |
|
Definition
env lapse rate>parcel= stable
vice versa= instability |
|
|
Term
| Why is the ozone so important in the layers of the atmosphere? |
|
Definition
| Ozone absorbs shortwavelength radition very effectively and filters out very harmful UV radiation |
