Weather

Question 1

What are the stages of Factors Affecting Precipitation?

Answer 1

1-Westerly wind picks up moisture from the Atlantic.
2-Air is forced to rise over the mountains.
3-Air cools as it rises.
4-Cooling causes cloud droplets to form (condensation).
5-Further cooling causes water droplets to form (precipitation).
6-Air descents, warms and produces drier conditions. This is called a rain shadow.

Answer 7

Hot weather
Cold weather
Dry weather
Wet weather

Question 8

What impacts does Hot Weather have?

Answer 8

Tourists may visit the coast->Improve the local economy.
People will suffer sunstroke-> Health risk.
Hot and Dry weather->Causes droughts and water shortages.

Question 9

What impacts does Cold Weather have?

Answer 9

Frost and Ice->Slips and trips become more common->More pressure on the NHS.
Use of more heating->Heating costs will increase.
School may close if pupils can’t safely travel->School closing.

Question 10

What impacts does Dry Weather have?

Answer 10

Dry weather->Droughts and water shortages.
Hosepipe bans may be introduced->Make sure people have enough water for essential purposes.
Dry weather is more pleasant for outdoor exercise->Recreation outside will be more common.

Question 11

What impacts does Wet Weather have?

Answer 11

Prolonged Wet weather->Cause flooding of properties and businesses.
Wet weather provides water->Essential for farmers growing crops.
Lots of Snow->Cause traffic issues due to the need to grit roads, slower driving and more collisions.

Question 12

What do the Isobars show?

Answer 12

Isobars are lines showing equal air pressure. The further the Isobar lines are the less winds there are. The closer they are more wind is.

Question 13

What are Weather Fronts?

Answer 13

Weather Fronts mark the front of a section of Warm or Cold air.
Warm Front-Semi Circles
Cold Front-Triangles
Occluded Front-Semi Circle and Triangle

Question 14

What are the 5 stages of Depression?

Answer 14

1-As the Warm front Approaches.
2-At the Warm front.
3-In the Warm sector.
4-At the Cold front.
5-As the Cold front Passes.

Question 15

Describe the first stage of a Depression (As the Warm front Approaches).

Answer 15

The Air Pressure starts to Decrease.
The Temperature is Relatively Cold.
The Cloud Cover Thins.
The Precipitation is none (no rain).

Question 16

Describe the Second stage of Depression (At the Warm front).

Answer 16

The Air Pressure lowers.
The Temperature is warmer.
The Cloud Cover gets thicker.
The Precipitation is steady rain.

Question 17

Describe the Third Stage of Depression (In the Warm sector).

Answer 17

The Air Pressure is low and decreases.
The Temperature is at its warmest.
The Cloud Cover is light.
The Precipitation is it has occasional showers.

Question 18

Describe the Fourth stage of Depression (At the Cold Front).

Answer 18

The Air Pressure is low.
The Temperature drops and becomes cold.
The Cloud Cover is thick again.
The Precipitation is heavy rain.

Question 19

Describe the Fifth stage of Depression (As the Cold Front passes).

Answer 19

The Air Pressure rises again.
The Temperature is cool.
The Cloud Cover is a clear sky.
Precipitation is when the rain stops.

Question 20

What are the Weather conditions in an Anticyclone during Summer?

Answer 20

The temperature in the Daytime- Hot because there is more heat entering the Earth.
Temperature at Night- Cold because heat can freely escape as little cloud cover.
Cloud Cover- Very little because of high air pressure as air can’t rise to form clouds.
Precipitation- Dry because there are no clouds or weather fronts to bring rain.
Wind Speed- Light because Isobars are spaced far apart.
Wind Direction- Westerly because wind rotates clockwise around a high-pressure system.

Question 21

What are the Weather conditions in an Anticyclone during Winter?

Answer 21

Temperature in Daytime- Cold because there is less heat entering the Earth.
Temperature at Night- Very cold because heat can freely escape as little cloud cover.
Cloud Cover- Very little because of high air pressure as air can’t rise to form clouds.
Precipitation- Dry because there are no clouds and weather fronts to bring rain.
Wind Speed- Light because Isobars are spaced further apart.
Wind Direction- Westerly because wind rotates clockwise around a high-pressure system.
