Chapter 3 Air Temperature This chapter focuses on the temperature of the air above the Earth’s surface. It examines air temperature, its measurement, and the factors that cause it to vary both temporally and spatially. This chapter also introduces the topic of global warming. Five important factors influencing air temperature are: insolation latitude surface type coastal versus interior location elevation Temperature is a measure of the sensible heat of a substance which changes as energy flows across its surface. When the net radiation (the balance between incoming shortwave and outgoing longwave radiation) of a surface is positive, the surface temperature rises, and when net radiation is negative, the surface temperature falls. Heat energy can be transferred by conduction , by latent heat transfer, and by convection . The daily cycles of insolation and net radiation peak at solar noon, while the daily cycle of air temperature peaks in the mid-afternoon. Air temperature measured above an
