Study Notes
Solar Radiation and Insolation
- The term for the energy received by the earth from the sun is insolation.
- The earth is farthest from the sun on July 4th, and nearest on January 3rd.
- The tilt of the earth's axis (23.5°) masks the variation in solar output due to the earth's distance from the sun.
Factors Influencing Insolation
- Latitude causes variation in insolation, with the equator receiving the most insolation.
- Angle of inclination of the sun's rays influences the variability of insolation at the surface of the earth.
- Aspect influences the variability of insolation at the surface of the earth.
- Distance from the sea influences temperature, with places near the sea generally having a higher temperature.
- Altitude influences temperature, with places at higher altitudes having lower temperatures.
Atmospheric Heating and Cooling
- Long wave radiations heat up the atmosphere from below.
- Clear sky allows radiation to escape, leading to a lower temperature at low levels.
- Advection is relatively more important than convection in middle latitude regions.
- Convection heats up the atmosphere from below.
Temperature and Climate
- Temperature inversion occurs when warm air lies over cold air, leading to an increase in temperature with altitude.
- Advection and convection influence the temperature of a place.
- Distance from the sea and altitude influence temperature.
- Latitude influences temperature, with the equator having the highest temperatures.
Other Phenomena
- Dense fogs occur in the mornings, especially during winter, due to radiation cooling.
- Air drainage in hills and mountains during winter nights leads to a temperature decrease.
- Isotherms are more or less parallel to the latitudes in January in the northern hemisphere.
- The thermal equator lies to the south of the geographical equator in January due to the apparent movement of the sun.
