Question 1

The magnitude of the Coriolis force:
A)increases with latitude
B)decreases with latitude
C)is unaffected by latitude

Accepted Answer

The magnitude of the Coriolis force is proportional to the sine of the latitude, which means it increases as you move away from the equator towards the poles. This is because the Earth's rotation causes objects to follow a curved path as they move, and the curvature is greater at higher latitudes.

Question 2

In a cyclone located in the southern hemisphere winds:
A)converge in a clockwise direction
B)converge in a counterclockwise direction
C)diverge in a clockwise direction
D)diverge in a counterclockwise direction

Accepted Answer

In the southern hemisphere, cyclones cause winds to converge (move towards the center of the cyclone) in a clockwise direction due to the Coriolis effect.

Question 3

The Hadley cell circulations are bounded to the north and south by:
A)polar fronts
B)trade winds
C)subtropical convergence zones
D)subtropical high pressure belts

Accepted Answer

The Hadley cell circulations are characterized by warm air rising in the equatorial regions, moving towards the poles at high altitude, sinking back down at approximately 30 degrees north and south latitude, and then returning towards the equator at low altitude. The sinking air at 30 degrees north and south creates high pressure belts known as subtropical highs. Therefore, the Hadley cells are bounded to the north and south by subtropical high pressure belts.

Question 4

The cold dry air that dominates the Asian monsoon during the winter originates from:
A)the Aleutian low
B)the Siberian high
C)the Hawaiian high
D)none of the above

Accepted Answer

The Siberian high is a large area of high pressure that forms over the continent of Asia during the winter months. The sinking air associated with this high pressure system causes cold and dry conditions to dominate the region, including the Asian monsoon.

Question 5

Which of the following is not part of Hadley cell circulation?
A)subtropical high pressure belts
B)the ITCZ
C)the westerlies
D)none of the above

Accepted Answer

The westerlies are part of the Ferrel cell circulation, which is located between the Hadley and Polar cells. Therefore, it is not part of the Hadley cell circulation.

Question 6

A cyclone is a:
A)circular low pressure cell
B)linear trough of low pressure
C)circular high pressure cell
D)linear ridge of high pressure

Accepted Answer

A cyclone is a circular low pressure cell that is characterized by rotating winds and inward spiraling winds.

Question 7

The magnitude of the Coriolis force is largest at the:
A)poles
B)mid-latitudes
C)tropics
D)equator

Accepted Answer

The magnitude of the Coriolis force is proportional to the sine of the latitude. At the poles, the sine of the latitude is equal to 1, while at the equator it is equal to 0. Therefore, the Coriolis force is largest at the poles.

Question 8

An anticyclone is a:
A)circular low pressure cell
B)linear trough of low pressure
C)circular high pressure cell
D)linear ridge of high pressure

Accepted Answer

An anticyclone is a circular high pressure cell. It is characterized by calm and sunny weather due to the sinking air at its center.

Question 9

The zone of convergence of air masses along the equatorial trough is the:
A)subtropical high pressure belt
B)easterly wave zone
C)Hawaiian high
D)intertropical convergence zone

Accepted Answer

The zone of convergence of air masses along the equatorial trough is the intertropical convergence zone (ITCZ), where the northeast trade winds and the southeast trade winds converge. This convergence results in uplift of warm, moist air, producing clouds and precipitation. The ITCZ is an important feature of global atmospheric circulation and plays a key role in regulating climate and weather patterns in tropical regions.

Question 10

The subtropical high pressure belts are zones of:
A)rising air and frequent rain
B)rising air and clear conditions
C)descending air and frequent rain
D)descending air and clear conditions

Accepted Answer

The subtropical high pressure belts are characterized by descending air which inhibits the formation of clouds and results in clear conditions. These belts are also associated with dry weather patterns.

Question 11

The Hadley cell circulations cause ______ along the ITCZ:
A)weak surface winds
B)strong uplift
C)heavy rains
D)all of the above

Accepted Answer

The Hadley cell circulation in the tropics causes strong uplift and heavy rains along the ITCZ. Additionally, the converging trade winds along the ITCZ can also create weak surface winds. Therefore, all of the options A, B, and C are correct.

Question 12

The distinctive weather pattern caused by monsoon circulation is:
A)wet summers and dry winters
B)dry summers and wet winters
C)hot summers and cold winters
D)warm summers and mild winters

Accepted Answer

Monsoon circulation typically results in wet summers and dry winters due to the seasonal reversal of winds, bringing heavy rainfall during the summer months when the land heats up and draws in moisture-laden air from the ocean.

Question 13

The low-latitude atmospheric circulation cell with rising air over the equatorial trough and sinking air over the subtropical high pressure belts is the:
A)convection loop
B)sea breeze
C)Hadley cell
D)trade cell

Accepted Answer

The description matches the Hadley cell, which is a large-scale atmospheric circulation cell named after George Hadley who first described it in the 18th century. It involves rising air over the equatorial trough (also known as the Intertropical Convergence Zone) and sinking air over the subtropical high-pressure belts. The other options (A, B, and D) do not accurately describe this specific atmospheric circulation cell.

Question 14

In a cyclone located in the northern hemisphere winds:
A)converge in a clockwise direction
B)converge in a counterclockwise direction
C)diverge in a clockwise direction
D)diverge in a counterclockwise direction

Accepted Answer

In the northern hemisphere, cyclones have a counterclockwise rotation due to the Coriolis effect. This means that the winds converge towards the center of the low-pressure system in a counterclockwise direction.

Question 15

In an anticyclone located in the northern hemisphere winds :
A)converge in a clockwise direction
B)converge in a counterclockwise direction
C)diverge in a clockwise direction
D)diverge in a counterclockwise direction

Accepted Answer

In an anticyclone located in the northern hemisphere, the air descends and then spreads outwards in all directions. Due to the Coriolis effect, the air turns towards its right, which means that the air diverges in a clockwise direction. Therefore, option C is the correct answer.

Question 16

In an anticyclone located in the southern hemisphere winds :
A)converge in a clockwise direction
B)converge in a counterclockwise direction
C)diverge in a clockwise direction
D)diverge in a counterclockwise direction

Accepted Answer

The answer of In an anticyclone located in the southern...

Question 17

Because of the Coriolis effect, surface winds flow:
A)parallel to isobars
B)from high pressure to low pressure
C)perpendicular to isobars
D)across isobars at an angle

Accepted Answer

The Coriolis effect causes surface winds to flow across isobars at an angle, resulting in a slight deflection to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This is known as the "geostrophic wind" pattern, and is responsible for the large-scale circulation of the atmosphere.

Question 18

Which is the following is a component of Hadley cells?
A)the doldrums
B)the trade winds
C)the ITCZ
D)all of the above

Accepted Answer

All of the given options- the doldrums, the trade winds, and the ITCZ are components of Hadley cells. The Hadley cells are large-scale atmospheric circulation patterns that occur between the equator and 30 degrees latitude in both hemispheres. The doldrums refer to a zone of low pressure near the equator, while the ITCZ (Inter-Tropical Convergence Zone) is a belt of low pressure that circles the Earth near the equator, where the northeast and southeast trade winds meet. The trade winds, which blow towards the equator from the subtropical high-pressure zones, are also a component of Hadley cells.

Question 19

Along the intertropical convergence zone:
A)surface winds are light and variable
B)rain is frequent and heavy
C)uplift is strong
D)all of the above

Accepted Answer

Surface winds are light and variable because of the converging airflows. The convergence of air leads to strong uplift, which results in frequent and heavy rainfall along the intertropical convergence zone.

Question 20

The changing weather conditions of monsoon circulation are associated with shifts in the position of the:
A)ITCZ
B)polar fronts
C)equatorial high ridge
D)none of the above

Accepted Answer

Monsoon circulation is characterized by a reversal of winds caused by differences in heating between land and sea. This results in the migration of the Intertropical Convergence Zone (ITCZ), which is the zone where the northeast and southeast trade winds converge, causing heavy rainfall. As the ITCZ shifts, it affects the weather conditions in the regions affected by monsoons. Therefore, the position of the ITCZ is closely associated with the changing weather conditions of the monsoon circulation.
