Meteorology: Understanding the Atmosphere Ackerman and Knox
Use this applet to explore how the temperature and moisture (represented by the wet-bulb temperature) below the cloud base determine the type of precipitation that reaches the ground. You might want to review concepts of wet bulb temperature before exploring this applet.
Some questions to consider:
Set the temperatures and wet bulb temperatures by dragging the points and learn what type of precipitation will fall to the ground. Each time you release the mouse button, the simulation starts. (And try to see what influence an updraft in the cloud has on precipitation.)
