Q

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

A

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

Mid-Latitude Cell

Polar Cell

13
Q

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

14
Q

The height of the tropopause varies with …..

16
Q

Vertical movement of air:

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

A

warms, free of wx

17
Q

In rising air surface pressure …..

18
Q

The stratosphere is the region above the …..

A

troposphere and tropopause

20
Q

Temperatures at the ozone layer …..

21
Q

The tropopause marks the …..

A

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
31
The stratosphere rises up to ..... to meet the ozone layer
50km
32
What clouds are found in the stratosphere .....
only TCU and CB's
33
In falling air, surface pressure .....
increases
34
The equitorial trough moves further north than it does south because .....
The mid summer surface tempreatires are higher at any given latitude in the northern hemispher because of the greater land mass
35
The height of the troposphere in Australian latitudes is approximately .....
10km
36
The troposphere rises from ..... to .....
8km to 18km
