The climate system1

(Naturally varying)

The Climate System



Differences or variability over different timescales
Differences (or variability) over different timescales

  • Millennial

  • Centennial

  • Decadal

  • Interannual

  • Seasonal

  • Daily

  • Hourly

Let’s look at Google Earth’s weather overlays for hourly variation

Then go to spatial scales


  • Stop slide show

  • Go to Google Earth (pre-set to Weather & Terrain only)

  • Expand weather layer

  • Comment on cloud patterns observed over eastern Atlantic

  • Click cloud animation in Temporary Places

  • Turn off weather layer



  • Go over UK if not there introducing spatial scales

  • Turn on weather layer

  • Draw attention to weather data and temperature

  • Zoom in to bring more stations

  • Click on station – note features (and that probably from analysis, not real data)




Sources of data or ideas
Sources of data or ideas ahead) – hence mismatch in patterns

  • Royal Meteorological Society MetLink site (www.metlink.org)

  • Meteorological Office Weather Observations Website (wow.metoffice.gov.uk/home)


Suggestions For Weather Space- Time Differences Questions That Can Be Explored With Student Observations

  • Variation over time at home (hourly, daily or longer)

  • Variation over school catchment at same time (synoptic view)

  • For those with solar panels – how does power generation relate to cloudiness?


Any Questions? That Can Be Explored With Student Observations
