  2. World Pattern of Climate • Understand factors affecting the world pattern of climate • Be able to recognise the variations and locations of climate types 17 November 2014

  3. World Climate Zones Insolation Revolution & Rotation Atmospheric Composition Ocean & Continent Distribution Topography Local Variations Polar - very cold and dry all yearTemperate - cold winters and mild summersArid - dry, hot all yearTropical - hot and wet all yearMediterranean - mild winters, dry hot summersMountains (tundra) very cold all year 17 November 2014

  6. Major Factors Affecting the World Pattern of Climate • Insolation variations • Revolution and Rotation • Atmospheric Composition • Ocean & Continent Distribution • Topography • Local Variations 17 November 2014

  7. Local Variations • Sea & Land Breezes • Anabatic & Katabatic Winds • Aspect 17 November 2014

  8. Local Variations – Sea Breezes Sea Breezes • Any problems? • Ruin day at beach – colder • Wind shear • Inshore boating 17 November 2014

  9. Local Variations – Land Breezes Weaker & less common than sea breezes Dependant on local topography 17 November 2014

  10. Anabatic Winds An anabatic wind is a wind which blows up a steep slope or mountain-side during the day, driven by sunshine heating the slope. A hill or mountain-top is warmed by the sun, which in turn heats the air just above it. This air becomes relatively warmer and lighter than other air at a similar altitude over an adjacent valley which does not get warmed as much because of the greater distance to the ground below it and / or if it is in shade. This warmer, lighter air will rise through convection, creating a lower-pressure region into which the higher-pressure air at the bottom of the slope gets drawn, causing the wind. 17 November 2014

  11. Katabatic Winds Opposite of Anabatic Wind, downslope movement as air cools. Can form fog or mist at bottom of slope in valley 17 November 2014
