A snowfall consists of myriads of minute ice crystals that fall to the ground in the

form of frozen precipitation. The formation of snow begins with these ice crystals in

the subfreezing strata of the middle and upper atmosphere when there is an adequate

supply of moisture present. At the core of every ice crystal is a minuscule nucleus, a

(5)  solid particle of matter around which moisture condenses and freezes. Liquid water

droplets flouting in the supermodel atmosphere and free ice crystals cannot coexist

within the same cloud, since the vapor pressure of ice is less than that of water. This

enables the ice crystals to rob the liquid droplets of their moisture and grow continuously.

 

The process can be very rapid, quickly creating sizable ice crystals, some of which

(10)  adhere to each other to create a cluster of ice crystals or a snowflake. Simple flakes

possess a variety of beautiful forms, usually hexagonal, though the symmetrical shapes

reproduced in most microscope photography of snowflakes are not usually found in

actual snowfall. Typically, snowflakes in actual snowfalls consist of broken fragments

and clusters of adhering ice crystals.

 

(15)  For a snowfall to continue once it starts, there must be a constant inflow of moisture

to supply the nuclei. This moisture is supplied by the passage of an airstream over a

water surface and its subsequent lifting to higher regions of the atmosphere. The Pacific

Ocean is the source of moisture for most snowfalls west of the Rocky Mountains, while

the Gulf of Mexico and the Atlantic Ocean feed water vapor into the air currents over

(20)  the central and eastern sections of the United States. Other geographical features also

can be the source of moisture for some snowstorms. For example, areas adjacent to the

Great Lakes experience their own unique lake-effect storms, employing a variation of

the process on a local scale. In addition, mountainous sections or rising terrain can

initiate snowfalls by the geographical lifting of a moist airstream.
