Caption: Seasonal changes in air temperature for fifty years, from 1950-1999. Temperature is colour-coded, from blue (coldest) to red (hottest). The seasonal fluctuation due to the Earth's tilt on its axis is evident. High ground (such as the Andes) has a temperature largely unaffected by seasons due to its altitude. The effect of other systems is also seen - despite being further south than the British Isles, Newfoundland (at the eastern tip of North America) is a lot colder, as western Europe is warmed by the Gulf Stream. The original data are from the Global Historical Climatology Network, which is part of NOAA's National Climatic Data Centre. The data was interpolated by the Centre for Climatic Research at the University of Delaware.
