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.
