The chapter begins with a limited description of the vertical temperature structure of the atmosphere and devotes most of its space to a consideration of forcing mechanisms that affect the local temperature structure. This chapter provides an excellent opportunity to explain the implications of differences in temperature trends between the troposphere and the surface.

In the tropics, the temperature is hardly linear with height, given that the lapse rate associated with the moist adiabat goes from about 5 K/km near the surface to almost 9.8 K/km at the tropopause near 16 km. It should also be noted that the tropopause descends sharply to 12 km near 30 degrees latitude and to around 8 km near the poles.

Further, there are limitations associated with usmg numerical models to examme the importance of mternal variability because such models poorly characterize such things as El Niilo/Southern Oscillation (ENSO) , the 1976 regime shift, and the quasi-biennial oscillation (QBO)

carefully note that water vapor and especially clouds are areas of major uncertainty m models, and even m nature.
