Weather and Climate

what is climate
What is climate?
  • Climate is:
  • Climate is
  • Examples of weather vs climate:

the average of day to day weather over a long duration

  • Today the temperature is 68F (weather).
  • Los Angeles has warm summers (climate).

Weather and Climate

controls on climate
Controls on Climate
  • Seasonal temperature and precipitation patters are generally attributable to:
  • Latitude
  • Mountains and highlands
  • Pressure and wind systems
  • Land and water location
  • Ocean currents
  • Prevailing wind direction

Weather and Climate

climate controls latitude mountains
Climate controls: Latitude/Mountains
  • Latitude
  • Mountains
  • Higher latitude climates are generally colder
  • Lower latitudes warmer and more moist
  • Higher altitudes: cooler temperatures
  • Windward side of mountains, cooler and wetter than leeward side

Weather and Climate

controls on climate oceans
Controls on Climate: Oceans
  • Ocean Temperatures
    • Coasts of continents are affected by ocean temperatures: Generally less temperature extremes compared to interior of continents
    • Cold oceans:
    • Warm oceans:
  • generally produce cooler/drier conditions
  • generally produce more warm/humid conditions

Weather and Climate

controls on climate pressure systems
Controls on Climate: Pressure systems
  • Rising and sinking motion associated with low and high pressure affects climate
  • Areas where pressure seasonally low, (rising motion)
  • Areas where pressure seasonally high, (sinking motion)
  • Deep Tropics: rainy
  • Subtropical high: warm and dry
