1. HADLEY (equator)
2. FERREL (mid)
3. POLAR (poles)

Question 13

MORE or LESS

Land heats ____ quickly than sea

Answer 13

MORE

Question 14

MORE or LESS

Sea cools ____ quickly than land

Answer 14

MORE

Question 15

Air movement from high pressure to low pressure is known as what

Answer 15

PRESSURE GRADIENT WIND

Question 16

A bigger pressure difference in gradient wind causes WEAKER or STRONGER wind

Answer 16

STRONGER

Question 17

What is an isobar

Answer 17

Line of constant atmospheric pressure

Question 18

Winds are weaker when isobars are ____

Answer 18

FURTHER APART

Question 19

Winds are ____ when isobars are closer together

Answer 19

STRONGER

Question 20

What is the name of the force that deflects wind due to earths rotation

Answer 20

CORIOLIS FORCE

Question 21

In the Northern Hemisphere, airflow is deflected in which direction

Answer 21

RIGHT

Question 22

When the coriolis force and pressure gradient force balance, this is known as what

Answer 22

GEOSTROPHIC WIND

Question 23

In the NH, which direction do LOW PRESSURE systems flow

Answer 23

ANTI CLOCKWISE

REMEMBER: Wind in your back, HIGH to the RIGHT
Face the wind, you are LEFT HIGH and DRY (Facing wind, high pressure is on your left)

Question 24

In the NH, which direction do HIGH PRESSURE systems flow

Answer 24

CLOCKWISE

Question 25

What type of cyclone is a high pressure system

Answer 25

ANIT CYCLONE ## Footnote [REVIEW HERE](https://docs.google.com/document/d/1gwlhKSWXy3Yj5hN74ZyoT0jBjHvn2LEzJSXeqfs4u4Q/edit#bookmark=id.9xov3mr2axj9)

Question 26

What type of cyclone is a low pressure system

Answer 26

CYCLONE ## Footnote [REVIEW HERE](https://docs.google.com/document/d/1gwlhKSWXy3Yj5hN74ZyoT0jBjHvn2LEzJSXeqfs4u4Q/edit#bookmark=id.9xov3mr2axj9)

Question 27

What happens to air in a low pressure system

Answer 27

Air converges at the bottom of the low pressure area Air is turning anticlockwise Air heats up at the surface and ascends Air cools as it ascends Cold air at top of pressure system diverges ## Footnote [REVIEW HERE](https://docs.google.com/document/d/1gwlhKSWXy3Yj5hN74ZyoT0jBjHvn2LEzJSXeqfs4u4Q/edit#bookmark=id.9xov3mr2axj9)

Question 28

What happens to air in a high pressure system

Answer 28

Cold air converges at the top Cold air descends Air heats up as it ascends Warm air diverges at the bottom AIr flows from high to low ## Footnote [REVIEW HERE](https://docs.google.com/document/d/1gwlhKSWXy3Yj5hN74ZyoT0jBjHvn2LEzJSXeqfs4u4Q/edit#bookmark=id.9xov3mr2axj9)

Question 29

High pressure systems have BETTER or WORSE weather than Low pressure systems

Answer 29

BETTER

Question 30

HIGH or LOW pressure systems generally have worse visibility Why

Answer 30

1. HIGH 2. HAZE

Question 31

An aircraft is making correction for wind blowing from its right. Is it heading into BETTER or WORSE weather conditions

Answer 31

BETTER ## Footnote If you correct for wind to the right, typically you are flying into better weather If you face the wind, you are left high and dry [LINK](https://docs.google.com/document/d/1gwlhKSWXy3Yj5hN74ZyoT0jBjHvn2LEzJSXeqfs4u4Q/edit#bookmark=id.oe6awuxmmcok)

Question 32

How does an air mass gain its properties

Answer 32

Time spent travelling over certain regions ## Footnote i.e. cold air traveling across an ocean will become slightly warmer and more moist

Question 33

What are the 5 air masses over the UK

Answer 33

Tropical Maritime (mT) Polar Maritime (mP) Arctic Maritime (mA) Polar Continential (cP) Tropical Continental (cT) ## Footnote REMEMBER: MC APT **MC** = **M**aritime on the left **C**ontinental on the right **APT** = Descending order **A**rctic **P**olar **T**ropical

Question 34

List the condictions of the air masses Tropical Maritime (mT) Polar Maritime (mP) Arctic Maritime (mA) Polar Continential (cP) Tropical Continental (cT)

Answer 34

Tropical Maritime (mT) = WARM and WET Polar Maritime (mP) = COLD and WET Arctic Maritime (mA) = COLD and DRY Polar Continential (cP) = COLD and DRY Tropical Continental (cT) = WARM and DRY ## Footnote REMEMBER: Tropical is always WARM Continental is always DRY Maritime is always WET (except Arctic Maritime) Polar is always COLD
