This chapter introduces learners to tropical meteorology including various methods of defining the tropics. An overview of energy balance and the global climate system is presented. The role of the tropics in the global energy and momentum balance is presented. Atmospheric structure of temperature and humidity are discussed in terms of latitudinal variability. Pressure ranges and scales of atmospheric motion in the tropics are reviewed. Seasonal and geographic distribution and the diurnal cycle of surface temperature and the influencing factors are examined in detail. Finally, we review tropical air masses and tropical climates.
At the end of this chapter, you should be able to:
Understand the concept of radiation balance between intake and loss of energy by the earth and atmosphere
Describe the role of the tropics in the global climate system
List the mechanisms that allow for exchange of energy between the surface and the atmosphere
Recall at least three methods of defining the tropics
List the components of the surface energy budget
Understand the atmosphere and ocean transport in the global energy balance
Describe how latent heat and tropical deep convection fit into the global energy budget
