These droplets, which have a diameter of about 10 <a href="/wiki/Micrometre" title="Micrometre">μm</a> (0.00039 in) on average, can exist in the liquid <a href="/wiki/State_of_matter" title="State of matter">state</a> at temperatures as low as −40 °C (−40 °F), far below the normal <a href="/wiki/Freezing" title="Freezing">freezing</a> point as long as above the homogeneous <a href="/wiki/Nucleation" title="Nucleation">nucleation</a> point of water. Contact between a snow crystal and the supercooled droplets results in freezing of the liquid droplets onto the surface of the crystal. This process of crystal growth is known as <a href="/wiki/Accretion_(atmosphere)" class="mw-redirect" title="Accretion (atmosphere)">accretion</a>. Crystals that exhibit frozen droplets on their surfaces are often referred to as <a href="/wiki/Hard_rime" class="mw-redirect" title="Hard rime">rimed</a>. When this process continues so that the shape of the original snow crystal is no longer identifiable and has become ball-like, the resulting crystal is referred to as graupel.<sup id="cite_ref-emu_4-0" class="reference"><a href="#cite_note-emu-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> </p><p>As graupel falls, it often deforms into a conical shape. This conical shape, in turn, determines which direction it falls and how far it travels as it falls. Small graupel particles with a base diameter less than 1mm generally fall with the conical base down, but if the particle is between 1mm and 3mm persistent oscillations around the center of the conical base appear, and if larger than 3mm the graupel particle will start to tumble. As the base diameter increases, conical graupel particles generally further horizontally from where it initially fell.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> </p><p>Graupel was formerly referred to by meteorologists as "soft hail." Graupel is distinguishable from true hail in both the shape and strength of the pellet and, in some cases, the circumstances in which it falls. Ice from <a href="/wiki/Hail" title="Hail">hail</a> is formed in hard, relatively uniform layers and usually falls only during <a href="/wiki/Thunderstorm" title="Thunderstorm">thunderstorms</a>.
