Study Notes
Layers of the Atmosphere
- The atmosphere has a thickness comparable to an onion's skin, crucial for life on Earth.
- Protects from harmful solar radiation and maintains warmth via the Greenhouse Effect.
- Divided into four main layers based on temperature:
- Troposphere: Contains most of the atmosphere's water and where weather occurs; temperature decreases with altitude.
- Stratosphere: Contains the ozone layer which absorbs UV light, increasing temperatures with altitude.
- Mesosphere: Coldest layer, reaching -100°C; most meteors burn up here.
- Thermosphere: Temperatures can exceed 2000°C, but air is too thin to breathe.
Latitudinal Distribution of Incoming Radiation
- Maximum solar radiation is observed at the equator and minimum at the poles.
- Radiation spreads over greater areas at higher latitudes due to beam depletion by the atmosphere.
Latent Heating and Convective Cloud Distribution
- Latent heat transfer is essential for energy transport and atmospheric circulation.
- Condensation and precipitation release latent heat, while evaporation removes it.
- Tropical oceans are key moisture sources for convection, influenced by surface heat fluxes.
Mean Outgoing Longwave Radiation (OLR)
- OLR from 1979 to 1995 indicates patterns of energy emitted by deep convective clouds.
- Areas with blue and red show the lowest OLR.
Annual Cycle of Cloud Tops
- Significant spatial and temporal changes in convective areas affect global climate dynamics.
Surface-Atmosphere Interactions
- Integral for energy transport within the tropics.
- Evaporation driven by wind momentum enhances water movement and energy exchange.
Atmospheric Structure and Heating
- Troposphere is primarily heated from below via latent heat and longwave radiation.
- Tropical regions experience a vertical expansion, with the tropopause at 18 km, higher than at the poles (averaging 11 km).
Seasonal and Geographic Temperature Distribution
- Tropics maintain a low temperature range (<1.5°C), with more significant variances found in midcontinental areas.
- Australia exhibits the highest temperature range (21-32°C) among tropical continental regions.
Diurnal Temperature Variability
- Factors affecting mean diurnal temperature range:
- Humidity moderates temperature variation; higher moisture leads to cooler daytime high temperatures.
- Cloudiness cools days and warms nights, reducing the diurnal range.
- Wind speed enhances mixing of air, moderating temperature extremes.
- Albedo: High reflectivity surfaces remain cooler than low reflectivity ones.
- Elevation impacts heating, causing distinct temperature patterns between mountain and valley areas.
Extreme Temperatures in the Tropics
- Tropical regions can experience extreme temperature variations due to local environmental factors.
