What Causes Precipitation
|Will you have precipitation today?|
When clouds develop or precipitation occurs, something is making the air
rise. When air rises it expands and gets colder and since colder air cannot hold
as much moisture as warm air, the water condenses to form clouds and sometimes
rain or ice or snow!
Several things can make the air rise...Mountains for one! Most blobs of air
do not carry shovels with them so they have to go over mountains instead of
through them! Cold fronts can cause air to rise as well. Even the jet stream can
cause air to rise.
Most precipitation is caused by a combination of different processes causing
the air to rise.
hail, rain, freezing rain, sleet, snow
