Geography-Weather

• Weather


  The day-to-day changes in the atmosphere
• Climate


  The average atmospheric conditions found in a given area
• Weather differs from climate


  Climate is the average atmospheric conditions found in a given area
• Weather forecasts


  Predictions about what the weather is likely to be in the upcoming days and weeks
• Weather measurements can be used to create forecasts
• UK weather forecasts are becoming more accurate
• Instruments used to collect weather data


  • Rain gauges
  • Thermometers
  • Anemometers
• Weather refers to the day-to-day changes in the atmosphere
• We can measure atmospheric conditions, such as air pressure and wind direction, to create weather forecasts
• People rely on weather forecasts to decide things like what to wear and what to do
• Some people rely on weather forecasts to carry out their jobs, for example those working outside
• Where weather data is collected


  • On the land - at weather stations
  • In the sea - weather buoys
  • In the air - aeroplanes and radar
  • From space - satellites
• Thermometer


  Measures temperature in degrees Celsius (°C) and/or degrees Fahrenheit (°F)
• Rain gauge


  Measures rainfall in millimetres (mm)
• Barometer


  Measures air pressure in millibars (mb)
• Anemometer


  Measures wind speed in miles per hour (mph)
• Weathervane


  Shows the wind direction
• The atmosphere is complex and ever-changing, which makes it difficult to forecast the weather
• UK weather forecasts are put together by organisations including the Met Office
• In addition to data collected at ground level, forecasters also use measurements recorded by aeroplanes, weather buoys at sea, radar and satellites
• The supercomputers that are needed to create weather forecasts are becoming faster and more powerful
