Hoarfrost. Crystals of hoarfrost frozen on a wire fence. Hoarfrost forms when condensation falls below zero degrees Celsius. If the air is still,water droplets crystallise around "condensation nuclei" such as dust particles on surfaces. For hoarfrost crystals to form,the surface temperature must also be below freezing point | |
