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
