4+What+Affects+the+Weather

=What Affects Weather and Climate?=

**Task 1)**
====**a)** Insert the diagram below into your notes. It shows why temperatures decrease as you travel north or south from the equator. This is the effect of **Latitude or distance from the equator. Once you have inserted the diagram, read the information from the link.**====


 * b) Describe** how temperature changes as you move away from the equator.

We start with Altitude or height above sea level ====**a)** Insert the photograph above and diagram below on Altitude into your notes . Then use the links above to **describe** in your own words how altitude can affect the temperature. Write your descriptions next to the diagram.====

b) Look again at the photograph above. You will notice that the snowline is different in different parts of the valley. This is due to the Aspect of the mountain side. The aspect is the the direction the slope faces. Try to explain in your own words how the Aspect can affect the temperature. Refer to the photograph in your answer.

Task 3: Distance From the Sea
====Compare these two weather forecasts. Now look at the diagram above that shows how the distance from the sea can affect temperatures in winter and summer. This link will explain how Distance from the sea affects the climate. Insert the diagram above and then use the link to make notes in your word document.==== media type="custom" key="28948718"media type="custom" key="28948720"

====The next to factors we will look at are Ocean currents and the Prevailing wind.====




 * a) Go back to the top of the page** and look at the map of the page. What climate zones are the UK and Newfoundland in Canada.

//Can you find Davis Inlet on Google Maps.?//

 * b) Use the diagram above to explain why the UK is warmer than Newfoundland.**


 * c) Copy this paragraph into your notes.**

//The prevailing wind is the most frequent wind direction a location experiences. In Europe the prevailing wind is usually from the south west, which brings warm, moist air from the Atlantic Ocean. This contributes to the frequent rainfall. When prevailing winds blow over land areas, it can contribute to creating desert climates. //

//**Extension: Prevailing Wind, The Föhn **//

**d)** Use this link and other websites to explain what the Föhn Wind is, how it is formed and the effect it has on the weather of Switzerland.

Convection Rainfall

Convection Rainfall is associated with the formation of **Cumulonimbus clouds**. Watch the clouds form in the video below.

Orographic Rainfall:

====**1)** Insert the image above into your notes under the title, Orographic/Relief Rainfall. Once you have done this, use the diagram to explain why the climate on the south side of the Alps (The Ticino) is much drier than the northern side.====

Frontal Rainfall:

//Frontal Rainfall Worksheets//




//High Pressure: Anticylones//




====**2)** You are now going to play a game of spot the difference. Try to find the similarities and differences between the two photographs. Annotate (label) the diagrams to show the similarities and differences you spot.====

====//Both photographs were taken during periods of **high pressure** known as **'Anticyclones.'** The air is cold and sinking. Cold air cannot hold very much water and therefore there are very few clouds. As the air sinks, it warms and therefore condensation doesn't take place. No condensation means no clouds and therefore no rain.//====

====//Anticyclones tend to give fine settled weather which may last several days. They can cover huge areas. In summer they bring hot and sunny weather. In winter they bring clear skies, low temperatures and a risk of fog and frost.//====

Revision
BBC Bitesize weather and climate pages with test. This is an excellent revision page. Although the emphasis is on British weather, the information is the same for most of western Europe.
