Precipitation Types
Snow
Snow forms when there’s moisture in the air in the form of Ice crystals. These crystals collide forming
Snow flakes. If enough collide they will become heavy enough to fall to earth. The size of the flake
depends on the air temperature so generally below zero the flakes will small while above zero they
will be larger. The heaviest Snowfalls in this Country tends to between 0C and 2C.
Snowflakes start melting above zero this also causes the air around them to cool. If the precipitation
is heavy enough the cooling effect can cause the Snow to reach ever lower levels in a process called
evaporative cooling.
Snowflakes are a collection of ice crystals that occur in a infinite number of forms. Indeed every
Snowflake is unique although they form hexagonal structures.

Snow Pellets
Also known as Graupel or formerly Soft hail. This forms when Snow crystals encounter super cooled
water droplets which collect and freeze on falling Snow flake eventually hiding the original Snow
crystal. Snow pellets are totally different from hail which is formed from hard ice and only falls in
thundery conditions. Snow pellets tend to be fragile and easily fall apart when touched.
