Ice a density about one quarter of that of pure ice. Hard rime is comparatively dense. Ice pellets are a form of precipitation consisting of small, translucent balls of ice. This form of precipitation is also referred to as "sleet" by the United States National Weather Service. (In British English "sleet" refers to a mixture of rain and snow). Ice pellets are usually smaller than hailstones. They often bounce when they hit the ground, and generally do not freeze into a solid mass unless mixed with freezing rain. The METAR code for ice pellets is "PL". Ice pellets form when a
Reindeer hunting in Greenland there can be cornices, crevasses, and avalanches, although snow can make it easier to spot and track reindeer. The weather during the beginning of the autumn hunting season is often pleasant, relatively warm, and mild, but it can change very quickly. Hunters may encounter fog, rain, wind, and winter conditions. Occasionally the situation can quickly approach a worst-case scenario with events such as katabatic winds, storms, snow, hail, sleet, freezing rain, blizzards, and polar cyclones, even in the late summer. Lack of preparation can have fatal consequences. Using a compass in Greenland involves accounting for a very extreme magnetic declination.
