Without Solar Power they wouldn’t be there. The Sun (Solar Power) causes water to evaporate (forming water vapor in the air). It causes air to rise to a level where it cools and condenses forming clouds (made of water droplets and ice crystals). If/when the weight of combined cloud crystals/droplets becomes heavy enough, they may become precipitation – which may be snow if it is cold enough. [Also involved is the unequal heating of the rotating earth by the sun producing air pressure systems and winds.]
But of course solar power from the sun can also melt the snow – hence the conflict.
