    • 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
