Winter has come and the beautiful Swiss mountains are even more sugar coated than before. In the Bernese highlands it has been snowing nonstop for the past couple days. Just imagine being in a giant flurry of fluffy white flakes. If you look closely at falling snow, you can see a great many different crystal shapes. In 1951 the International Commission on Snow and Ice produced a fairly simple and widely used classification system for solid precipitation. This system defines the seven principal snow crystal types as plates, stellar crystals, columns, needles, spatial dendrites, capped columns, and irregular forms. To these are added three additional types of frozen precipitation: graupel, ice pellets, and hail.
But maybe instead of classifying the snow flakes just enjoy them. because we just love data. and snow.
