global atmospheric circulation

Question 1

why is it hot at the equator

Answer 1

the suns energy is more concentrated

Question 2

is there rising air or sinking air at the equator

Answer 2

rising air

Question 3

why does air rise at the equator

Answer 3

because it is hot and hot air is less dense and rises

Question 4

is rising air linked to wet or dry conditions

Answer 4

wet

Question 5

does rising air create high or low pressure

Answer 5

low

Question 6

why is rising air associated with rainfall

Answer 6

because as the air rises, it cools ands and condenses, forming clouds that lead to rainfall

Question 7

what type of weather is associated with low pressure at the equator

Answer 7

warm and wet

Question 8

is there a high pressure or low pressure built 30degrees north and south of the equator

Answer 8

high pressure

Question 9

do high pressure belts have rising air or sinking air

Answer 9

sinking air

Question 10

what type of weather is associated with high atmospheric pressure

Answer 10

dry

Question 11

is there a high or low pressure 60degrees north and south of the equator

Answer 11

low

Question 12

what type of climate is found where the ferrel cell meets the polar cell

Answer 12

mild and wet

Question 13

what are the winds called that blow from 30degrees north towards the equator

Answer 13

trade winds

Question 14

why is it cold at the poles

Answer 14

the suns energy is spread out over a large area

Question 15

why is it dry at the poles

Answer 15

there is sinking air with high atmospheric pressure

Question 16

What is wind

Answer 16

wind is the movement of air from high pressure to low pressure

Question 17

What happens in the hadley cell

Answer 17

1.hot air rises creating a low pressure belt
2.once air has reached high altitudes it moves away north and south
3.as the air moves away from equator is begins to cool and sink
4.sinking cool air creates a high pressure belt 30degrees north
5.once air has hit the surface some air moves back to the equator as trade winds. (COMPLETING THE HADLEY CELL) whilst the rest moves north as westlies to begin the ferrel cell

Question 18

what happens in the ferrel cell?

Answer 18

1.winds moving north meets cold winds from the polar cell.
2.the warmer ferrel cell winds are forced to rise, creating a low pressure belt 60degrees north (COMPLETING THE FERREL CELL)

Question 19

what happens in the polar cell

Answer 19

1.air moving north in the polar cell cools and sinks at 90degrees north creating high pressure
2.winds move from high pressure 90degrees to low pressure at 60degrees (COMPLETING THE POLAR CELL)
