It was named by the UK Antarctic Place-Names Committee in 1958 for Erasmus Bartholin, of Copenhagen, whose " De Figura Nivis Dissertatio ", 1661, includes the earliest known scientific description of snow crystals.

One those comparatively rare occasions when it snows near 0 F, you can expect individual snow crystals, but not very many of them because such cold air can't " hold " as much water vapor.

A recording from this period is Slobodan Kova evi's first instrumental composition " Snje ~ ni kristali " ( Snow Crystals ), which was recorded in the studio of Radio Sarajevo on April 16, 1965.

Consequently, despite the shape of snowflakes is very diverse with no two flakes similar to each other, most snow crystals are symmetric with each of the six branches almost identical to other five branches.

One hundred and fifty-one of her schematic drawings were used to illustrate her husband's paper, " On the Severe Weather at the beginning of the year 1855 : and on Snow and Snow Crystals, " published by the Meteorological Society.

Four types of crystal size are provided based on its usage : large crystals ( 10 40 mm ), small crystals ( 2 10 mm ), snow crystals ( less than 2 mm ), and windswept powder ( less than 0.15 mm ).

Bentley poetically described snowflakes as " tiny miracles of beauty " and snow crystals as " ice flowers . " Despite these poetic descriptions, Bentley brought a highly objective eye to his work, similar to the German photographer Karl Blossfeldt ( 1865 1932 ), who photographed seeds, seed pods, and foliage.

Among the agents inserted in selected clouds were " condensation nuclei " which temporarily increased the number of water droplets in the cloud, and pulverized dry ice, which turns a portion of the cloud to fine snow crystals that remain aloft . The utilization of these agents facilitated study of a storm's characteristics.

From 1936 to 1949, Ukichiro Nakaya created artificial snow crystals and charted the relationship between temperature and water vapor saturation, later called the " Nakaya Diagram " and other works of research in snow, which were published in 1954 by Harvard University Press publishes as " Snow Crystals : Natural and Artificial ".
