After reading Chapter 6, you should be able to:
- Describe the heat properties of water, and identify the traits of its three phases: solid, liquid, and gas.
- Define humidity and the expressions of the relative humidity concept; explain dew-point temperature and saturated conditions in the atmosphere.
- Identify the various types of clouds.
- Define atmospheric stability and relate it to a parcel of air that is ascending or descending.
- Illustrate three atmospheric conditions—unstable, conditionally unstable, and stable—with a simple graph that relates the environmental lapse rate to the dry adiabatic lapse rate (DALR) and the saturated adiabatic lapse rate (SALR).
- Describe the two processes by which precipitation forms and identify the different types of precipitation.
