Learning Objectives

Each statement represents an important learning objective that relates to one or more sections of this lab. After you complete this exercise you should be able to:

List and describe the processes involved when water changes state.

Express the relationship between temperature and saturation mixing ratio.

Define relative humidity and explain how changes in mixing ratio and temperature affect relative humidity.

Relate dew point temperature to relative humidity and saturation mixing ratio.

Use a psychrometer and appropriate tables to determine the relative humidity and dew-point temperature of air.

Describe the typical daily pattern of variations in air temperature and relative humidity.

Explain the process of adiabatic cooling and warming. Calculate the temperature and relative humidity changes that take place in air as a result of adiabatic temperature changes.

Explain how air pressure is measured and how pressure tendency is related to cloudy or clearing weather.

Describe the relationship between air pressure and wind.

Briefly explain how the Coriolis effect influences wind.

Relate the global distribution of precipitation to global pressure zones. List other factors that influence the distribution of precipitation.
