What happens to Temperature and pressure with height through the atmosphere?
Objectives
The Atmosphere is Dynamic - Insolation, Albedo and the Heat Budget
1. Try to produce a flow chart from the text I read to you
2. Look at pages 208 to 209 of David Waugh and answer the following;
a) Describe how the solar energy cascade works.
b) What is insolation? How and why can it vary?
c) What is albedo? How does it vary for different surfaces? What impact does this have globally?
d) The heat budget – describe the heat budget then explain it.
Incoming radiation100 units
Small amount absorbed in
Stratosphere (1%)
Clouds absorb small amounts (3%)
and reflect more (20%)
Earth – 45% of incoming radiation reaches the Earth’s
surface
24% absorbed
by atmosphere
Small amounts (4%) are
reflected back to space by the Earth’s surface
24% reaches
the Earth’s surface
Scattering – 21% reaches the earth as diffuse radiation, the rest is scattered back
to space
Review Why is the Heat budget important? Explain the flow chart below as a class;
