The temperature of our atmosphere is controlled by a complex set of interactions between the biosphere, lithosphere, hydrosphere, and atmosphere. Energy is constantly exchanged between the surface and the air above, as well as circulating around the globe. Here we'll look at what controls the air temperature at a particular place by examining radiation and energy exchanges between the earth and air above. Then we'll examine how the global circulation of air and water affects air temperature.
By the end of the chapter you should be able to:
- Define temperature and describe how air temperature is measured.
- Explain what controls daily and seasonal temperature variations.
- Determine the temperature gradient using isotherms.
- Calculate average daily and annual temperature, daily and annual temperature range, determine seasonal temperature lag.
- Explain the global pattern of air temperature.
- Summarize the effects of global warming on temperature patterns.
