large data set

• The large data set is a collection of data points collected by the UK Met Office of the weather between May and October in 1987 and 2015
• locations in large data set

  • Leuchars (Scotland)
  • Leeming (northern England)
  • Heathrow (London)
  • Hurn (southern coast of England)
  • Camborne (south-west England)
  • Perth (western Australia)
  • Jacksonville (Florida, USA)
  • Beijing (China)
• the large data set recorded

  • temperature (degrees Celsius)
  • pressure (hectopascals)
  • rainfall (mm)
  • wind speed (knots/Beaufort scale)
  • gust speed
  • wind direction (cardinal directions/degrees from north)
  • sunshine (hours)
  • cloud cover (oktas)
  • visibility (decametres)
  • humdity (percent)
• the yearly average temperature increased in all locations except for Perth, where it stayed at 15.2 degrees
• Leuchars had the lowest mean temperature in both years, while Jacksonville had the highest in both years
• Rainfall doubled in Jacksonville across both years
• In the UK locations, for volumes of rain between 0mm and 0.05mm, the Met Office recorded them as traces of rain, represented by tr, makes statistical tests for the UK less accurate
• gust speed is the maximum wind speed in a day
• wind speed in the UK is measured to the nearest integer while outside the UK is was rounded to 1 decimal place
• Beaufort scale for wind speed

  • light = 0-10 knots
  • moderate = 11-16 knots
  • fresh wind = 17-21 knots
• wind and gust direction were only measured in the UK locations like gust speed
