  • Weather
    • Water Cycle
      • Surface Run Off
      • ground water flow
      • Trough Flow
    • Weather Instruments
      • Rain Gauge
        • Measures Percipitation
          • Units of measurement:mm
            • Water falls into the funnel at the top and collects in the basin and foot of the gauge. The volume of water can be measured each day
      • Thermometer
        • measures temperature
          • Units of measurement: c/f
            • The mercury in the base of the thermometer expands and contracts with heat.
      • Anemometer
        • Measures wind speed
          • Units of measurement:mph
            • Wind turns the cups around, the stronger the wind the faster it spins.
      • Wind Vane
        • Measure wind direction
          • Units of measurement: compass direction
            • The arrow spins around and points to where the wind is coming from
      • Campbell Stokes/ Sunshine Recorder
        • Measures duration and intensity of sunlight
          • Units of mesaurement: hours
            • The glass ball focuses the sun's rays onto a piece of paper which it burns. You can then measure the length of the burn against the hourly markings on the paper.
      • Barometer
        • Measures air pressure
          • Units of measurement:mb
            • The force of air exerted on  the barometer is recorded
      • Naked Eye
    • Microclimate Causes
      • Surface
        • The colour of the ground surface affects warming.
        • Park surfaces such as turmac and soil will become warmer than lights sufaces such as grass
      • Aspect
        • The direction in which a place is facing
        • Places facing the sun will be wormer than those in the shados
      • Shelter
        • Trees,hedges buildings evne hills can provide shelter.
        • Wind speed may be reduced and its direction changed.
      • Physical Features
        • Trees provide shade and shelter. Usually cooler than the area surrounding it
        • Hill tops are usually cool and windy.
        • Water areas such as lakes have a cooling effect and may produce winds
      • Buildings
        • Buildings store heat and give it out in the afternoon
        • Temperatures near buildiungs may be 2C or 3C highjer than the surroundings.
        • Buildings close to each other can break winds. It would be warmer especially in the afternoon
