Question 1

What is Latitude

Answer 1

Latitude is places closer to the equator are usually warmer, and places nearer to the North Pole and South Pole are colder.

Question 2

what is relief?

Answer 2

Relief is places located on flat low-lying land and warmer and places higher up, ie mountains, are south-facing are warmer and places which are north-facing are colder.

Question 3

what is an Aspect?

Answer 3

An Aspect is places which are south-facing are warmer and places which are north-facing are colder.

Question 4

what is Distance from the sea?

Answer 4

Distance from the sea are places nearer to the sea and mild wet, and places further from the sea are drier, but temperatures are more extreme.

Question 5

What is an airmass?

Answer 5

An air mass is a large volume of air which travels from one area to another. The weather an air mass brings is determined by the region it has come from and the type of surface it has moved over.
There are five main air masses which affect the UK as detailed by the map below.

Question 6

Warm front

Answer 6

In a low pressure system the warm front is the first to pass over. This occurs when warm air meets cold air and the warm air rises above it. Warm fronts bring steady continuous rain.

Question 7

Cold front

Answer 7

The next front to pass over is the cold front. This occurs when cold air meets warm air. The cold air pushes the warm air upwards. Cold fronts bring heavy rain showers.

Question 8

Occluded front

Answer 8

When the cold front catches up with the warm front the result is an occluded front. Occluded fronts bring sudden downpours of heavy rain.

Question 9

Depression characteristics

Answer 9

Where isobars are close together the wind is greatest. This is because of a rapid change in air pressure.

Question 10

High pressure systems anticyclones

Answer 10

An anticyclone is an area of high pressure which brings long periods of settled weather. An area of heavy cool air sinks and it warms up as it does so. As it warms it is able to hold more moisture. This means clouds do not form. High pressure systems can be identified from a synoptic chart due to widely spaced isobars no fronts/clouds isobars showing pressure increasing outwards front the centre and above 1008mb.
