Study Notes
Fronts in Climate Change
- Fronts are boundaries where different air masses meet, leading to shifts in weather.
- These air masses have varying temperatures and moisture levels.
- Collisions between air masses can trigger storms and temperature changes.
- Understanding fronts is crucial in predicting climate change's impact on weather patterns.
Earth Energy Balance
- The Sun sends light and heat to Earth.
- Approximately 30% of this energy is reflected back into space.
- The remaining energy is absorbed by the atmosphere, oceans, and land, warming them.
- Heat (long-wave radiation) is released back into the atmosphere.
- Gases in the atmosphere trap and redistribute this heat, keeping Earth warmer.
Greenhouse Effect
- Gases like CO2 trap heat in the atmosphere, acting like a blanket.
- This process, the greenhouse effect, warms the planet beyond what it would be without these gases.
- This phenomenon was first recognized by Jean-Baptiste Fourier in 1827.
- Greenhouse gases allow sunlight to pass through but prevent some heat from escaping, maintaining Earth's temperature.
- Without greenhouse gases, Earth would be significantly colder.
Radiative Forcing
- Radiative forcing measures the impact of various factors on Earth's energy balance.
- Factors influencing energy balance include greenhouse gases, clouds, and aerosols.
- Positive forcing leads to warming by trapping more energy.
- Negative forcing leads to cooling by allowing more energy to escape.
- Radiative forcing is measured in watts per square meter (W/m²).
- On average, 340 W/m² of solar radiation enters Earth's atmosphere interacting with various factors.
