Surface type (urban or rural), elevation, latitude, daily and annual insolation cycles, and location (maritime or continental) all can influence air temperatures. Now let’s put all these factors together and see how they affect world air temperature patterns. First, we need a quick explanation of air temperature maps. Figure shows …

Temperature Structure of the Atmosphere
In general, the air is cooler at higher altitudes. Most incoming solar radiation passes through the atmosphere and is absorbed by the Earth’s surface. The atmosphere is then warmed at the surface by latent and sensible heat flows. So it makes sense that, in general, air farther from the Earth’s …

On a hot day, rural environments will feel cooler than urban environments. In rural areas, water is taken up by plant roots; it then moves to the leaves and evaporates from leaf pores in a process called transpiration. This process cools leaf surfaces, which in turn cool nearby air. Evaporation …

This chapter focuses on air temperature —that is, the temperature of the air as observed at 1.2 m (4 ft) above the ground surface. Air temperature conditions many aspects of human life, from the clothing we wear to the fuel costs we pay. Air tem-perature and air tempera-ture cycles also …
