World climates

  1. 1. WORLD CLIMATES
  2. 2. WEATHER AND CLIMATE • Weather is the atmospheric conditions here and now. • Climate is an average of conditions in a particular place over time
  3. 3. A COUNTRY’S CLIMATE DEPENDS ON FOUR MAIN FACTORS • Latitude is the distance of a location from the equator. The hottest temperatures are found at the equator. As you move further away from the equator towards the polar regions, less and less sun is received during the year and the climates become colder and colder. Altitude is the height above sea level or the height above the earth's surface. The higher the altitude, the lower the temperature will be. On average for every 1,000 metres higher you go the temperature will fall about 6.5 °C. Proximity to the sea affects the temperature of a place because the sea temperature changes slower than land temperature. So the sea will keep coastal areas warmer than inland area during the winter and cooler than inland areas during the summer. • Currents exist in all the oceans. Currents that move water from tropical areas towards the poles (North Atlantic Drift starts in the Gulf of Mexico) are known as warm currents. Those currents moving from northern (or southern) colder seas, nearer the poles towards the equator are known as cool currents, an example is the Canaries current
  4. 4. CLIMATE ELEMENTS • Temperature is how hot or cold the atmosphere is - ie, how many degrees Celsius (centigrade) it is above or below freezing (0°C) • farenheit and celsius scale
  5. 5. • Precipitation is the term given to moisture that falls from the air to the ground • pluviometer
  6. 6. • Atmospheric pressure (or air pressure) is the weight of air resting on the earth's surface. Pressure is shown on a weather map, often called a synoptic map, with lines called isobars. • Low pressure occurs when air becomes warmer. The air molecules expand, become lighter and it rises. • High pressure occurs when air becomes colder. The air molecules contract, become denser, heavier and sink towards the earth.
  7. 7. barometer
  8. 8. • Wind is the movement of air masses from high pressure areas (high) to low pressure areas (low). The effect of this movement of air is to rebalance the pressure in the atmosphere.

  13. 13. EQUATORIAL CLIMATE • Characteristics • Constant high temperatures. • Lowest annual temperature range of any climate. • Evenly distributed, heavy precipitation. • Lots of cloud cover and high humidity
  14. 14. Rainforest Biome • Biome: A biome is a large geographical area of distinctive plant and animal groups, which are adapted to that particular environment
  15. 15. Tropical dry-wet • Characteristics • wet season in summer,dry periods in winter. • Rainfall less than equatorial and monsoon. • Highest temperature ranges of low latitude wet climates

  23. 23. Chaparral biome
  24. 24. Humid continental • Characteristics • Warm Summer Subtype: • Hot humid summers; occasional winter cold waves. • Large annual temperature ranges. Ie. Chicago • Cool Summer Subtype: • Moderate summers; long cold winters. • Large annual temperature ranges. • Less precipitation than warm summer subtype • Ie. Winnipeg, Manitoba, Canada

  26. 26. Marine west coast • Characteristics • Mild winters, mild summers. • Low annual temperature range. • Heavy cloud cover; high humidity.
  27. 27. Biome: deciduous forest
  28. 28. Dry midlatitude climate • These dry climates are limited to the interiors of North America and Eurasia. • Cold winters and warm or hot summers. A small amount of rain falls during this season. • Annual temperatures range widely.
