(1)(a) Draw a climate graph to show the information on the weather in Dalwhinnie, Scotland.

Climate data for Dalwhinnie (altitude 351 metres) using averages for 1981 to 2010 (Annual precipitation = 1304.0 mm, temperature range = 12.9°C)

J F M A M J J A S O N D Max temp (°C) 4.3 4.5 6.4 9.4 13.0 15.3 17.2 16.6 13.9 10.2 6.8 4.6 Precipitation (mm)

179.0 123.7 127.0 63.7 70.0 64.5 68.7 79.9 99.8 147.2 143.1 137.4

(b) Compare your completed graph for Dalwhinnie in Scotland with Figure 1 which shows Reading in southern England. Write down any similarities and differences that you notice, and then think of the reasons for the differences in the weather of the two places and add these to your notes.

(c) Study the 3D Google maps image (Figure 3) which shows the part of Reading University where their weather station is located. (i) What are the advantages and disadvantages of taking weather measurements at the orange, red, blue and green locations?

(ii) Explain why the yellow location is the most suitable.

Some influences which decrease accuracy, for you to consider, are given below:

Interference from people passing In the shade of trees or buildings Sheltered by a building or vegetation or slope Close to the heat given off by buildings or hard surfaces Rain splash off a hard (impermeable) surface Close to higher evaporation from areas of water On a slope that may change amount of sunlight Close to water areas that moderate temperatures
