1. How Air Temperature Affects Precipitation

2. RAIN
We can get rain at the surface in several ways. Here are two
common ways this happens: 2) The air temperature where the precipitation
1) The air temperature from the starts is below freezing so snow is formed. As
clouds to the surface is above the snow falls, the air temperature rises above
freezing (32° F or 0°C). freezing and the snow melts into rain.

3. SNOW
The only way we can get
snow as precipitation on the
Earth’s surface is if the air
temperature from clouds to
surface stays below freezing
(32° F or 0° C).

4. SLEET
Sleet is frozen rain drops.
Sleet happens when rain falls
through an area of air that is
below freezing (32° F or 0°
C) before it hits the surface.
This ‘cold layer’ freezes the
rain, forming sleet.

5. FREEZING RAIN
Freezing rain is rain that
freezes as it hits the surface.
When the air temperature
in the atmosphere is above
freezing (32° F or 0°C), but
the surface temperature is
below freezing, freezing rain
can occur.
