Climates trabajo de sergio gutierrez fernandez Climates trabajo de sergio gutierrez fernandez Presentation Transcript

  • What are the world’s main climates? -British, Mediterranean, cold, equatorial, hot desert and tropical continental.
  • Affecting temperature is: latitude, distance from the sea, prevailing winds, altitude, and… How?
  • Temperatures in equatorial climate
  • Rainfall in the tropical continental (savanna) climate. -During the dry season the prevailing trade winds blow from the east. The dry season is shorter towards the Equator and longer away from the Equator. The higher temperatures result in warm air being forced to rise to give frequent afternoon convectional thunderstorms.
  • Rainfall in the Mediterranean climate Temperatures in cold climates -They are high latitudes (60º and 75º both north and south of the Equator), very low indeed. North America, North Europe, North Russia, mountain areas (Himalaya) -We have short and cool summers. Winters are very long and very cold. Places north of the Arctic Circle have a period when the sun never rises above the horizon. Strong winds from the continental interior mean
  • Drought -Drought is a long period of weather that is drier than usual.
  • Drought in the world affects to:
  • -They are most common in late summer or autumn when sea temperatures are at their highest (26º C at least). At these temperatures water evaporates rapidly and as the rising air cools it condenses and releases enormous amounts of heat energy which powers the storm.
  • Global warming is…, and it is due to… Kyoto Protocol
  • -The Earth is surrounded by a layer of gases, including carbon dioxide. This keeps the Earth warm by preventing the escape of heat that would normally be lost from the atmosphere. The gases act rather like the glass in a greenhouse. They let heat in but prevent most of it from getting out. The burning of fossil fuels such as oil, coal and natural gas produces large amounts of carbon dioxide. As the amount of this gas increases, the Earth becomes warmer.
  • -Sea temperatures would rise, sea-levels could rise -Ice caps and glaciers would continue to melt -Low-lying areas would be flooded -There might more violent storms, and extremes of hot weather -Hot regions would become hotter and deserts would spread -Climatic and vegetation belts would move -Some plants and animals would become extinct -There could be an increase in insect pests -Tropical diseases may spread to temperature regions such as the UK.
