Rain Drops Keep Falling on my Head BJ Thompson 1969 INTRODUCTION How much rain do you get in your area How about snow This amount varies around the world For example people living in Spokane Washington get much more rain than those in Phoenix Arizona. .

Process of Precipitation:. Precipitation is caused by condensation of water . vapours. of the air mass. . The ascending air mass with sufficient amount of water . vapours. becomes saturated due to adiabatic cooling. Condensation of water . Precipitation can be divided into three categories. . based on whether it falls as liquid water, liquid water that freezes on contact with the surface, or . ice. Mixtures of different types of precipitation, including types in different categories, can fall simultaneously. . Mountains Experiment (OLYMPEX). Lynn McMurdie . University of Washington.
