12. Ocean currents The main ocean current that affects the UK is the Gulf Stream . The Gulf Stream is a warm ocean current in the North Atlantic flowing from the Gulf of Mexico, northeast along the U.S coast, and from there to the British Isles has a moderating influence over temperatures in coastal areas.

20. In winter the warmest parts of the UK are to the west and to the south where the NAD has a big influence The coldest areas are in the north where the sun is at a lower angle in the sky. I Temperature in July In summer, the warmest places are in the south. Warm air from Southern Europe often nudges into the south of the UK during the summer.

24. 2005 Q9A (ii) Level 1: (1 – 2 marks) Basic e.g. the south is closer to the sun in July so it is hotter. In winter, the west coast is warmer because of the warm current. Level 2: (3 – 4 marks) Clear The sun shines from the south so the south of England receives more of the sun’s energy. Further north the sun must travel further through the atmosphere so less energy is received. In winter, the east coast is colder because of cold north east winds and there is no warming effect from the North Atlantic Drift. Heat Island Effect, differential heating of land and sea, all acceptable but not reference to altitude. Allow imbalance between summer-winter to top of L2. Level 3: (5 – 6 marks) Detailed In summer, the main impact on temperature is the energy from the sun whereas in winter, the sun is so low in the sky that distance from the sea and warm ocean currents have a greater impact. Temperatures decrease as you move north in summer as the surface area being heated increases as does the distance through the atmosphere that the rays must travel. Hence, more energy is lost through scattering. In winter, the west coast is warmer due to the warm North Atlantic Drift and onshore winds that keep temperatures slightly higher. 6 marks
