Weather

• High pressure in winter (benefits)

  • Tourists come to go skeeing up in the highlands boosting the local economy.
  • going carolling and earning money for charity bringing festive spirit.
  • the cold naturally controls pests that can’t survive the temperature.
  • frost can help breakdown organic material in the soil making it more productive in the following growing season
  • demand for certain product
  • increases e.g turks sales good for fomess.
• High pressure in winter means (problems)

  • Cold overnight temperature/ freezing conditions which result in frost and icy roads resulting in people getting into accidents
  • isobars become close together so wind speed will increase making bridges dangerous for lorries.
  • Strong winds and heavy snowfall can potentially cause blizzards.
  • heating prices can increase as it is too cold and will become more expensive.
  • shop sales will decrease as people are less likely to go outside to shops in freezing temperatures.
• High pressure in summer (problems)

  • Drought may lead to crops failing and not growing.
  • extra irrigation costs may mean farmers go into debt.
  • head stroke meaning it might get to bad you have to go to hospital and take up beds that people need.
  • there could be forest fire breakouts meaning people near by need to evacuate.

• 5 air masses that effect the uk

  • Polar continental- from Northman Europe with cold and dry temperatures.
  • tropical continental- from the southern Europe and North Africa which have a warn and dry temperature.
  • artic maritime- from the artic ocean and very cold temperature. not always wet due to low humidity.
  • polar maritime- from the North Atlantic with cold and wet temperatures.
  • tropical maritime- from the Atlantic Ocean and has a warm and wet temperature.
• Anticyclone

  • Isobars are spread car apart bringing gentle winds when spread apart.
  • wind blows clockwise in high pressure and along the isobars.
  • in summer the skies are clear with little cloud and temperatures are high.
  • in winter skies also clear with little cloud, temperature is cold and maybe some frost.
  • the warm front clouds are called nimbostratus clouds
• Depressions

  • Isobars are close together the wind is heavy and has a rapid change in air pressure.
  • wind blows anticlockwise along the isobars by following an anticlockwise direction.
  • warn air is pushed up where it cools and precipitates with clouds and rain.
  • the warm sector behind the warm front brings warm temp but cloud front front brings cold temperatures.
  • the clouds in the cold front are called cumulonimbus clouds.
• Four factors that effect weather

  • Latitude- Scottish highlands are colder because they are further from the equator. This is due to the sun rays being less concentrated.
  • Altitude/relief- as altitude increases, temp decreases so places like Ben Nevis are colder than the surrounding low lands it gets 1°C colder for every 100m in height.
  • Aspect- places facing south are warmer because they get more sun places facing north are cold due to northerly winds.
  • Distance from the sea- in summer, places close to the sea are cooler because the sea takes longer to heat up snd also retains the heat for longer.
