Meteorology | Climatology and Global circulation

Question 1

The three global circulation cells and latitude

Answer 1

Hadley cell between 0 and 30 degrees
Ferrel cell between 30 and 60 degrees
Polar cell between 60 and 90 degrees

Question 2

Explain the type of flow at 0 degrees -

Answer 2

Rising air

Question 3

Explain the type of flow at 30 degrees -

Answer 3

Sinking air

Question 4

The subtropical high is found -

Answer 4

At 30 degrees

Question 5

Trade winds:

They are found between -

Caused by -

Direction for NH and SH

Answer 5

0 - 30 degrees

The outflow of air from the subtropical highs to the equator low, deflected by Coriolis forces.

NE in NH, SE in the SH

Question 6

Coriolis force in NH deflects to the -

Coriolis force in SH deflects to the -

Answer 6

Right.

Left

Question 7

Equatorial Low(trough):

Where is it found and how is it cause -

Significance -

Answer 7

At the equator, caused by hot air rising. The risen air cools at height and then move North to the subtropical high, where it sinks and finally flow back to the equator.

The return flow from the subtropical high is what causes the NE and SE trade winds

Question 8

Temperate low:

Where is it found -

Significance -

Answer 8

Temperate low is where the subtropical high and the polar air masses meet.

An area of convergence, the temperate low is defined by travelling depressions.

Question 9

Westerly winds:

Where is it found -

How is it caused -

Answer 9

Between the ferrel cell and the polar cell.

Caused by airflow from the subtropical high to the polar high in both hemispheres.

Question 10

The polar front is caused -

Answer 10

By the subtropical high meeting the polar high

Question 11

Easterlies:

Where is it found -

How is it caused -

Answer 11

Found in the polar cell.

Caused by the surface flow of polar high towards the subtropical high, but is variable and less strong.

Question 12

Equatorial Climate:

Location -

Type of weather -

Answer 12

between 0 and 10 degrees.

Convective activity with high rainfall and thunderstorms. Two rainy season March and September.

Question 13

There are two rainy seasons in the equatorial climate, these occur -

Answer 13

March and September

Question 14

Tropical transition climate(also knows as savannah):

Location -

Weather -

Answer 14

10 to 20 degrees.

Hot humid summers with thunderstorms, mild dry winters.

Question 15

Arid subtropical (also knows as steppe):

Location -

Weather -

Answer 15

20 - 35 degrees.

The subsiding air is cloudless and hot. Most of the earths deserts are here. NH: Sahara, Arabia, Arizona. SH: Kalahari, Australia

Question 16

Mediterranean Climate:

Location -

Weather winter and summer -

Answer 16

35 - 40 degrees

Winter:

Traveling frontal depressions, prevailing westerly winds, cloud and precipitation, cool and unsettled.

Summer:

Dry subtropical climate, anti-cyclonic, hot sunny weather, westerly upper winds.

Question 17

Disturbed Temperate:

Location -

Weather -

Answer 17

40 - 65 degrees

The weather is controlled by travelling frontal depressions. Winds are normally westerly. No dry season.

Question 18

Polar Climate(tundra):

Location -

Answer 18

65 - 90 degrees

Question 19

When are the rainy seasons in equatorial Africa?

Answer 19

March to May and October to November

Question 20

Along the West coast of India the prevailing winds are the:

Answer 20

SW monsoon in July and a NE monsoon in January

Question 21

What is the name of the northerly, cold and strong wind, that sometimes blows over a certain part of Europe?

Answer 21

Mistral

Question 22

The Chinook is a:

Answer 22

warm and dry wind that forms as air descends on the leeward side of the Rocky Mountains

Question 23

The Bora is a:

Answer 23

cold katabatic wind with the possibility of violent gusts

Question 24

What is the strong relatively cold katabatic wind, blowing down the northern Adriatic coast, mainly during the winter and spring called?

Answer 24

Bora

Question 25

What is the name of the wind or air mass which gives to the main part of India its greatest proportion of precipitation?

Answer 25

South west monsoon
