Topics in Temperature
1
Solar Radiation and Insolation
- Sun is the primary source of heat energy for Earth, located approximately 15 crore km away
- Nuclear fusion of hydrogen nuclei in Sun's core releases tremendous energy
- Sun's surface temperature: 6000°C, Central temperature: 1.5 crore°C
2
Factors Affecting Distribution of Insolation
- Angular length of Sun's rays: Vertical rays in tropics receive more heat, slanting rays in polar regions receive less
- Length of day: Longer days receive more insolation (summer > winter)
- Density of atmosphere and height: 40-50% insolation absorbed in atmosphere, thin atmosphere absorbs less
3
Heat Budget of Earth
- 18% insolation directly absorbed by atmosphere
- 47% insolation reaches and absorbed by Earth's surface
- 35% insolation reflected back as Albedo
4
Factors Affecting Temperature
- Latitude: Temperature decreases from equator to poles due to angular difference of Sun's rays
- Height above sea level: Temperature decreases with altitude (lapse rate 6.5°C/1000m)
- Distance from sea: Coastal areas moderate, continental areas extreme temperatures
