1

Which layer of the atmosphere absorbs the incoming radiation from the sun .....

the ozone layer

1

The isothermal layer has a ..... temperature

constant

1

The layer of atmosphere in which most convection takes place is the .....

troposphere

2

The belt of high pressure that appears over the Australian continent during the winter months is called .....

the sub tropical ridge

2

the monsoonal trough features extensive cloud and weather because .....

it is in a region where converging airstreams ruse over warm ocean due to the intensity of solar radiation

3

Mid-latitude cell = high/low pressure

high

4

beyond the ozone layer the temperature .....

reduces

5

The tropopause varies in height from ..... at the equator to ..... at the poles

18km at the equator and 8km at the poles

6

Polar cell = high/low pressure

low

7

The ozone layer is almost as ..... as the surface

warm

8

Temperature drops by ..... degrees per ..... feet

20 every 1000ft

9

When compared with the size of the earth, the troposphere is very thick/thin

thin

10

What clouds can penetrate beyond the tropopause .....

TCU and CB only

10

The ITCZ is .....

the region where the surface air flow from each hemisphere converges and rises

11

There is very little convection in the stratosphere becuase .....

the air at the top of the layer is warmer than the air at the bottom

12

The sub polar low occurs between ..... 

the polar cell and the mid-latitude cell

12

Draw the vertical movement of air with your minds eye

Tropical Cell

Mid-Latitude Cell

Polar Cell

13

Almost all of the convective wx occurs in the .....

Troposphere

14

The height of the tropopause varies with .....

latitude

16

Vertical movement of air:

Falling air ..... as it sinks and therefore tends to be .....

warms, free of wx

17

In rising air surface pressure .....

falls

18

The stratosphere is the region above the .....

troposphere and tropopause

20

Temperatures at the ozone layer .....

increase

21

The tropopause marks the .....

roof of the troposphere

22

Equatorial trough = high/low pressure

low

24

Migration occurs because .....

the equatorial trough moves further north in summer than it does south

25

What are the temps doing in the stratosphere .....

they are constant and rising towards the ozone layer

27

Vertical movement of air:

Rising air contains vast amounts of ..... ..... and this causes .....

water vapor, extensive wx

28

Why is there no wx beyond the tropopause .....

because here the convective air no longer cools with height

30

Vertical movement within the atmosphere becomes less vigorous above the height of the tropopause becuase .....

the environment no longer gets colder with increased height
