  • Understanding Weather, Climate, & the Seasons Tara Wasserstein
  • What is Weather?
    • The state of the atmosphere at a particular time and place.
    • Temperature, humidity, wind velocity, precipitation, and barometric pressure.
    • Occurs in the troposphere, or lower atmosphere; driven by energy from the Sun and rotation of the Earth.
    • Average weather conditions of a region over time are used to define a region's climate.
  • What is Climate?
    • General weather conditions of a certain region, including temperature, air pressure, humidity, precipitation, sunshine, cloudiness, and winds.
    • Climate is most affected by latitude, tilt of the Earth's axis, movements of the Earth's wind belts, difference in temperatures of land and sea, and topography.
  • What are Seasons?
    • One of four natural divisions of the year—spring, summer, autumn, and winter—in temperate zones.
    • Each has its own characteristic weather and lasts approximately three months.
    • Change in seasons is brought about by the shift in the angle at which the Sun's rays strike the Earth as the Earth orbits the sun.
  • Measuring Temperature
    • Temperature can be measured with the use of a thermometer.
    • Readings can be in Kelvin and Celsius, but are done most commonly in Fahrenheit.
    • Temperature determines how hot or cold gases and liquids are.
  • Interrelationships
    • Climate is determined by the weather patterns in a specific area.
    • Certain climates only exhibit some of the seasons based on their location on the Earth.
  • Types of Climates
    • There are 5 general types of climates:
      • Tropical - high temperatures, year-round rain
      • Dry - little rain, vast daily temperature range
      • Temperate - warm dry summers, cool wet winters
      • Cold - low precipitation, seasonal temps vary
      • Polar - permanent ice, temperatures below freezing
    • There exist several subgroups of climates, including:
      • Tropical moist, wet-dry tropical, dry tropical
      • Dry midlatitude, Mediterranean, moist continental
      • Boreal forest, tundra, highland
  • Patterns of Seasons
    • Reversed in Northern and Southern hemispheres

  • The 4 Seasons
    • Summer - Hot and dry
    • Autumn - Cool and dry
    • Winter - Cold and wet
    • Spring - Cool, wet and humid
