### A FRACTAL DERIVATIVE MODEL FOR SNOW'S THERMAL INSULATION PROPERTY

**ABSTRACT**

Snow is of porous structure and good thermal insulation property. A fractal derivative model is established to reveal its thermal property, it is extremely high thermal-stable, the whole snow will not be affected much by the sudden environmental temperature change. A simple experiment is carried out to verify the theoretical finding, and the result is helpful to design advanced materials mimicking the snow structure.
