Chapter 8.1 Atmospheric Lifting Mechanisms I.a. Lifting air masses cool adiabatically (by expansion) to reach dew-point temperature--> this moisture in saturated air can condense to form clouds or precipitation I.a. Four Principal Lifting Mechanisms I.a.i. Convergent Lifting : air flows toward an area of low pressure and displaces air upward I.a.i.1. Along equatorial regions, SE and NE trade winds converge, forming intertropical convergence zone (ITCZ) and areas of extensive uplift I.a.i.1. Cumulonimbus cloud development and high average annual precipitation I.a.i. Convectional Lifting : air is stimulated by local surface heating I.a.i.1. When air mass passes from maritime source region to warmer, continental region, heating from warmer land causes lifting and convection in air mass I.a.i.1. Unstable, continues to rise and clouds form I.a.i. Orographic Lifting : air is forced upward over a barrier such as a mountain range I.a.i.1. Stable air forced upward on a slope of a mountain--> stratiform clouds
