36
Q

What’s a synoptic chart?

A

A synoptic chart is a map that summarises the atmospheres conditions over a wide area at a given time

37
Q

What’s the main weather element on a synoptic chart?

A

On a synoptic chart the main weather element is air pressure

38
Q

What are isobar lines?

A

Isobar lines, which join up areas of equal air pressure are drawn on a synoptic chart
The patter these lines make show areas of low or high pressure

39
Q

What does it mean by isobars?

A

Isobars drawn close together on a map illustrate high winds, the wider the isobar the lighter the winds

40
Q

What happens the closer the isobars are?

A

The closer the isobars the faster the wind

41
Q

What does fronts mean?

A

Fronts mean rain there’s warm, cold and occluded front they all mean different things

42
Q

What does it mean by warm fronts?

A

Warm fronts are a long period of steady rain

43
Q

Whats warm fronts?

A

Warm fronts is a long period of steady rain

44
Q

Whats cold/occluded fronts?

A

Cold/occluded fronts are a shorter spell of heavy rain

45
Q

What happens between the warm and cold fronts?

A

The temperature between the warm and cold fronts is higher than outside them - this hotter area is called the warm sector

46
Q

Where do depressions move?

A

Usually depressions move west to east over Britain

47
Q

What affects temperature and precipitation in the uk?

A

There are 4 main ways in which the temperature and precipitation throughout the Uk are affected:
Latitude, aspect, relief, distance from the sea

48
Q

What is latitude?

A

Latitude is places closer to the equator that are usually warmer

49
Q

The further latitude is south the area is?

A

The further south the area is, the less atmosphere the suns rays have to pass through to reach the earth. This means that less heat is lost to clouds and gases in the atmosphere

50
Q

The further latitude north you go the area is?

A

The further north you go, the more curved the earth becomes. This means that the sun has to heat up a larger surface area. This means the heat is less concentrated in the north than the south

51
Q

What is aspect?

A

Aspect - this means the direction the land is facing. The sun rises in the east and sets in the west. Therefore the sun shines at it’s strongest when it is shining from the south (around midday). This means that southerly facing places will get much more sun than those places facing north.

52
Q

Why do north facing areas remain cooler?

A

The sun never shines directly from the north and so North facing areas remain cooler.

53
Q

What winds are southerly places sheltered from?

A

The winds from the north (Arctic) are usually the coldest. Southerly places are usually sheltered from these winds.

54
Q

Why do west facing places receive more wetter weather?

A

Land which faces the Atlantic Ocean (west facing) receive more of the wetter weather as the air has picked up moisture from the ocean. East facing areas are sheltered from this rain.

55
Q

What is relief?

A

Relief – This is the height and shape of the land. In general, the higher you go, the colder it gets (temperature decreases by 1 degrees Celsius for every 100 metres in height.) So if the temperature is around 18 degrees Celsius at the bottom of a 1000 metre mountain, the temperature at the top will be around 8 degrees Celsius

56
Q

What do higher areas get than lower areas?

A

Higher areas get more rain than lower areas. This is due to RELEIF RAINFALL.

57
Q

What is relief rainfall?

A

Relief rainfall means rain caused by the land varying in height. Relief rainfalls is formed when the air cools as it rises over relief features in the landscape such as hills or mountains. As the air rises, it cools, condenses and forms rain.

58
Q

Why does east get less rain than west?

A

Most of the rain from the Atlantic Ocean is dropped on the west of the UK. As the winds move east, they carry less moisture, and therefore the east gets much less rain than the west.

59
Q

What is distance from the sea?

A

Distance from the sea – In winter, the west of the UK is usually warmer than the east.

60
Q

Why is the west of the Uk during winter warmer than the east?

A

This is due to:
• The North Atlantic Drift (a warm water current) keeps the temperatures of the west warmer than they should be as the heat from the sea heats up the land.
• South West winds bring warmer air from the Atlantic Ocean.

61
Q

What is an air mass?

A

An air mass is a large body of air with similar temperature and/or humidity

62
Q

Where do air masses form?

A

Air masses form in stable “source regions” such as in the sun tropics or near to the poles

63
Q

What weather does Tropical bring?

A

It brings Warm/hot weather

64
Q

What weather does arctic bring?

A

It brings Cold,icy weather

65
Q

What weather does maritime bring?

A

It brings Moist air which brings wet weather

66
Q

What weather does continental bring?

A

It brings dry air which brings dry weather

67
Q

Where does tropical maritime air masses come from?

A

Tm (tropical maritime) air masses come from the south west and originates over the Caribbean. They bring mild, damp, cloudy weather.

68
Q

Where does tropical continental air masses come from?

A

Tc (tropical continental) air masses come from the south and originate over dry Northern Africa. This air will be dry as it has had no opportunity to pick up moisture from the ocean. They bring hot,dry weather and summer heatwaves

69
Q

Where does polar maritime air masses come from?

A

Pm (polar maritime) air masses come from the north-west and originate over the North Atlantic therefore picking up moisture as it moves towards the UK. They bring cool,moist conditions

70
Q

Where does polar continental air masses come from?

A

Pc (polar continental) air masses come from the east and originate over Scandinavia and Russia. They bring clear dry conditions - cold in winter, warm in summer

71
Q

What do warm fronts bring?

A

Warm fronts bring warm air behind them

72
Q

What do cold fronts bring?

A

Cold fronts bring cold air behind them
