Why do some places get more snow?

Wind direction

  • Snow is a type of . We get snow instead of rain when the air temperature is below 0°C (freezing).
  • In the UK, the air is cold enough for snow when the wind is blowing from extremely cold places like the Arctic regions to the north or from Siberia to the east.

Altitude

  • Another reason some places get more snow than others is . This is measured in metres above .
  • The higher up you go, the colder the air gets and you are more likely to get snow than rain.

Urban heat

  • Being in a city can also affect how much snow falls.
  • Cities are busy places. All the activity and energy of lots of people, traffic and buildings heats up the air. This heat can reduce the chance of snow. This is called urban heat.
  • When it is cold in winter, it is more likely to snow in the countryside, far from big towns and cities, than in a busy city centre.
  • An urban heat island is how we describe a busy town or city which experiences much warmer temperatures than nearby .
