    Study Notes

    Chapter 13: Earth Science - Weather vs. Climate

    • Brainstorming activity prompts thinking about the similarities and differences between weather and climate.
    • Weather refers to short-term atmospheric conditions (daily high and low temperature, rainfall, wind speed/direction, humidity, air pressure), while climate refers to long-term weather patterns.

    Annual Averages and Variations

    • Climatology is the study of Earth's climate and factors that affect past, present, and future.
    • Climate describes long-term weather patterns in a region.
    • Climate is determined by seasonal variations in temperature and precipitation.
    • Climate influences plant and animal life, and human activities.
    • Climate data is based on a 30-year average or "normal" to accurately reflect typical weather and conditions in a location.

    Factors Affecting Climate

    • Latitude: Higher latitudes receive less solar radiation, resulting in cooler climates.
    • Large bodies of water: Water heats up and cools down slower than land, resulting in more stable temperatures near coasts.
    • Mountains: Orographic lifting can cause rain on the windward side of a mountain, leaving the leeward side dry & warm.
    • Cities: Urban areas are warmer than surrounding rural areas due to absorption of heat by buildings and asphalt, and heat trapping effects of air pollution.
    • Air Masses: Regional climates are affected by air masses transporting temperature and humidity from their source regions.

    Causes of Climate

    • Latitude: The amount of solar radiation received determines temperature differences.
    • Large bodies of water: Water moderates temperature fluctuations. Coastal areas experience smaller temperature changes compared to inland areas.
    • Mountains: Topography influences rainfall; windward sides are wetter, leeward sides drier.
    • Air masses: Air masses transport temperature and humidity, influencing regional climates.

    Climate Zones Classification

    • Köppen System: A climate classification system developed by Wladimir Köppen, based on vegetation patterns reflecting different climates.
    • The Köppen system is used to categorize and classify different climates around the globe.

    Graphing Climate Data

    • A climatograph is a visual representation of climate data.
    • X-axis shows months of the year.
    • Y-axis shows temperature and precipitation.

    Long-Term Climatic Changes

    • Ice Ages: Periods of significantly lower global temperatures. The most recent ice age ended about 10,000 years ago.

    Short-Term Climatic Changes

    • Seasons: Regular variations in daylight, temperature, and weather patterns.
    • El Niño: A climate pattern causing changes in ocean currents & weather patterns over the Pacific.

    Natural Causes of Climatic Changes

    • Solar Activity: Variation in solar activity (sunspots) can influence global temperatures.
    • Earth's Orbit: Changes in Earth's orbital shape can affect the amount of solar radiation reaching Earth, influencing climate.
    • Earth's Tilt: Changes in the tilt of Earth's axis can affect the intensity and distribution of solar radiation, impacting climates on different parts of Earth.
    • Volcanic Activity: Large volcanic eruptions can release aerosols into the atmosphere, affecting solar radiation and global temperatures.

    Influence on the Atmosphere

    • Greenhouse Effect: Natural warming of Earth's surface due to atmospheric gases trapping heat.
    • Global Warming: Human activities (burning fossil fuels) are increasing greenhouse gas concentrations, leading to a warmer planet.

    Global Warming - Contributing Factors

    • Deforestation: Removal of trees reduces carbon dioxide absorption and increases it in the atmosphere.
    • Burning fossil fuels: Release of greenhouse gases into the atmosphere.
